INDUSTRIAL REVOLUTION

INDUSTRIAL REVOLUTION

Author:   Lewis Hackett  Date: 1992
Industrialization: The First Phase

Most products people in the industrialized nations use today are turned out swiftly by the process of mass production, by people (and sometimes, robots) working on assembly lines using power-driven machines. People of ancient and medieval times had no such products. They had to spend long, tedious hours of hand labor even on simple objects. The energy, or power, they employed in work came almost wholly from their own and animals' muscles. The Industrial Revolution is the name given the movement in which machines changed people's way of life as well as their methods of manufacture.
About the time of the American Revolution, the people of England began to use machines to make cloth and steam engines to run the machines. A little later they invented locomotives. Productivity began a spectacular climb. By 1850 most Englishmen were laboring in industrial towns and Great Britain had become the workshop of the world. From Britain the Industrial Revolution spread gradually throughout Europe and to the United States.

Changes That Led to the Revolution
The most important of the changes that brought about the Industrial Revolution were (1) the invention of machines to do the work of hand tools; (2) the use of steam, and later of other kinds of power, in place of the muscles of human beings and of animals; and (3) the adoption of the factory system.
It is almost impossible to imagine what the world would be like if the effects of the Industrial Revolution were swept away. Electric lights would go out. Automobiles and airplanes would vanish. Telephones, radios, and television would disappear Most of the abundant stocks on the shelves of department stores would be gone. The children of the poor would have little or no schooling and would work from dawn to dark on the farm or in the home. Before machines were invented, work by children as well as by adults was needed in order to provide enough food, clothing, and shelter for all.
The Industrial Revolution came gradually. It happened in a short span of time, however, when measured against the centuries people had worked entirely by hand. Until John Kay invented the flying shuttle in 1733 and James Hargreaves the spinning jenny 31 years later, the making of yarn and the weaving of cloth had been much the same for thousands of years. By 1800 a host of new and faster processes were in use in both manufacture and transportation.
This relatively sudden change in the way people live deserves to be called a revolution. It differs from a political revolution in its greater effects on the lives of people and in not coming to an end, as, for example, did the French Revolution.
Instead, the Industrial Revolution grew more powerful each year as new inventions and manufacturing processes added to the efficiency of machines and increased productivity. Indeed, since World War I the mechanization of industry has increased so enormously that another revolution in production is taking place
Expanding Commerce Affects Industry
Commerce and industry have always been closely related. Sometimes one is ahead and sometimes the other, but the one behind is always trying to catch up. Beginning in about 1400, world commerce grew and changed so greatly that writers sometimes use the term "commercial revolution" to describe the economic progress of the next three and a half centuries.
Many factors helped bring about this revolution in trade. The Crusades opened up the riches of the East to Western Europe. America was discovered, and European nations began to acquire rich colonies there and elsewhere. New trade routes were opened. The strong central governments which replaced the feudal system began to protect and help their merchants. Trading firms, such as the British East India Company, were chartered by governments. Larger ships were built, and flourishing cities grew up.
With the expansion of trade, more money was needed. Large-scale commerce could not be carried on by barter, as much of the earlier trade had been. Gold and silver from the New World helped meet this need. Banks and credit systems developed. By the end of the 17th century Europe had a large accumulation of capital. Money had to be available before machinery and steam engines could come into wide use for they were costly to manufacture and install.
By 1750 large quantities of goods were being exchanged among the European nations, and there was a demand for more goods than were being produced. England was the leading commercial nation, and the manufacture of cloth was its leading industry.

Organizing Production
Several systems of making goods had grown up by the time of the Industrial Revolution. In country districts families produced most of the food, clothing, and other articles they used, as they had done for centuries. In the cities merchandise was made in shops much like those of the medieval craftsmen, and manufacturing was strictly regulated by the guilds and by the government. The goods made in these shops, though of high quality, were limited and costly.
The merchants needed cheaper items, as well as larger quantities, for their growing trade. As early as the 15th century they already had begun to go outside the cities, beyond the reach of the hampering regulations, and to establish another system of producing goods.
From Cottage Industry to Factory
Cloth merchants, for instance, would buy raw wool from the sheep owners, have it spun into yarn by farmers' wives, and take it to country weavers to be made into textiles. These country weavers could manufacture the cloth more cheaply than city craftsmen could because they got part of their living from their gardens or small farms.
The merchants would then collect the cloth and give it out again to finishers and dyers. Thus they controlled clothmaking from start to finish. Similar methods of organizing and controlling the process of manufacture came to prevail in other industries, such as the nail, cutlery, and leather goods.
Some writers call this the putting-out system. Others call it the domestic system because the work was done in the home ("domestic" comes from the Latin word for home). Another term is cottage industry, for most of the workers belonged to the class of farm laborers known as cotters and carried on the work in their cottages.

This system of industry had several advantages over older systems. It gave the merchant a large supply of manufactured articles at a low price. It also enabled him to order the particular kinds of items that he needed for his markets. It provided employment for every member of a craft worker's family and gave jobs to skilled workers who had no capital to start businesses for themselves. A few merchants who had enough capital had gone a step further. They brought workers together under one roof and supplied them with spinning wheels and looms or with the implements of other trades. These establishments were factories, though they bear slight resemblance to the factories of today.
Why the Revolution Began in England
English merchants were leaders in developing a commerce which increased the demand for more goods. The expansion in trade had made it possible to accumulate capital to use in industry. A cheaper system of production had grown up which was largely free from regulation.
There also were new ideas in England which aided the movement. One of these was the growing interest in scientific investigation and invention. Another was the doctrine of laissez-faire, or letting business alone. This doctrine had been growing in favor throughout the 18th century. It was especially popular after the British economist Adam Smith argued powerfully for it in his great work 'The Wealth of Nations' (1776).
For centuries the craft guilds and the government had controlled commerce and industry down to the smallest detail. Now many Englishmen had come to believe that it was better to let business be regulated by the free play of supply and demand rather than by laws. Thus the English government for the most part kept its hands off and left business free to adopt the new inventions and the methods of production which were best suited to them.
The most important of the machines that ushered in the Industrial Revolution were invented in the last third of the 18th century. Earlier in the century, however, three inventions had been made which opened the way for the later machines. One was the crude, slow-moving steam engine built by Thomas Newcomen (1705), which was used to pump water out of mines. The second was John Kay's flying shuttle (1733). It enabled one person to handle a wide loom more rapidly than two persons could operate it before. The third was a frame for spinning cotton thread with rollers, first set up by Lewis Paul and John Wyatt (1741). Their invention was not commercially practical, but it was the first step toward solving the problem of machine spinning.

Inventions in Textile Industry
As the flying shuttle sped up weaving, the demand for cotton yarn increased. Many inventors set to work to improve the spinning wheel. James Hargreaves, a weaver who was also a carpenter, patented his spinning jenny in 1770. It enabled one worker to run eight spindles instead of one.
About the same time Richard Arkwright developed his water frame, a machine for spinning with rollers operated by water power. In 1779 Samuel Crompton, a spinner, combined Hargreaves' jenny and Arkwright's roller frame into a spinning machine, called a mule. It produced thread of greater fineness and strength than the jenny or the roller frame. Since the roller frame and the mule were large and heavy, it became the practice to install them in mills, where they could be run by water power. They were tended by women and children.

These improvements in spinning machinery called for further improvements in weaving. In 1785 Edmund Cartwright patented a power loom. In spite of the need for it, weaving machinery came into use very slowly. First, many improvements had to be made before the loom was satisfactory. Second, the hand weavers violently opposed its adoption because it threw many of them out of work. Those who got jobs in the factories were obliged to take the same pay as unskilled workers. Thus they rioted, smashed the machines, and tried to prevent their use. The power loom was only coming into wide operation in the cotton industry by 1813. It did not completely replace the hand loom in weaving cotton until 1850. It was not well adapted to the making of some woolens. As late as 1880 many hand looms were still in use for weaving woolen cloth.
Many other machines contributed to the progress of the textile industry. In 1785 Thomas Bell of Glasgow invented cylinder printing of cotton goods. This was a great improvement on block printing. It made successive impressions of a design "join up" and did the work more rapidly and more cheaply. In 1793 the available supply of cotton was increased by Eli Whitney's invention of the cotton gin. In 1804 J.M. Jacquard, a Frenchman, perfected a loom on which patterns might be woven in fabrics by mechanical means. This loom was later adapted to the making of lace, which became available to everyone
Watt's Steam Engine
While textile machinery was developing, progress was being made in other directions. In 1763 James Watt, a Scottish mechanic, was asked to repair a model of a Newcomen steam engine. He saw how crude and inefficient it was and by a series of improvements made it a practical device for running machinery.
Wheels turned by running water had been the chief source of power for the early factories. These were necessarily situated on swift-running streams. When the steam engine became efficient, it was possible to locate factories in more convenient places.

Coal and Iron
The first users of steam engines were the coal and iron industries. They were destined to be basic industries in the new age of machinery. As early as 1720 many steam engines were in operation. In coal mines they pumped out the water which usually flooded the deep shafts. In the iron industry they pumped water to create the draft in blast furnaces.
The iron industry benefited also from other early inventions of the 18th century. Iron was scarce and costly, and production was falling off because England's forests could not supply enough charcoal for smelting the ore. Ironmasters had long been experimenting with coal as a fuel for smelting. Finally the Darby family, after three generations of effort, succeeded with coal that had been transformed into coke. This created a new demand for coal and laid the foundation for the British coal industry. The next great steps were taken in the 1780s, when Henry Cort developed the processes of puddling and rolling. Puddling produced nearly pure malleable iron. Hand in hand with the adoption of the new inventions went the rapid development of the factory system of manufacture.

Changing Conditions in England
The new methods increased the amount of goods produced and decreased the cost. The worker at a machine with 100 spindles on it could spin 100 threads of cotton more rapidly than 100 workers could on the old spinning wheels. Southern planters in the United States were able to meet the increased demand for raw cotton because they were using the cotton gin. This machine could do the job of 50 men in cleaning cotton. Similar improvements were being made in other lines of industry. British merchants no longer found it a problem to obtain enough goods to supply their markets. On the contrary, at times the markets were glutted with more goods than could be sold. Then mills were closed and workers were thrown out of employment.
With English factories calling for supplies, such as American cotton, and sending goods to all parts of the world, better transportation was needed. The roads of England were wretchedly poor and often impassable. Packhorses and wagons crawled along them, carrying small loads. Such slow and inadequate transportation kept the cost of goods high. Here again the need produced the invention. Thomas Telford and John MacAdam each developed a method of road construction better than any that had been known since the ancient Romans built their famous roads.
Building Canals and Railways
Many canals were dug. They connected the main rivers and so furnished a network of waterways for transporting coal and other heavy goods. A canalboat held much more than a wagon. It moved smoothly if slowly over the water, with a single horse hitched to the towline. In some places, where it was impossible to dig canals and where heavy loads of coal had to be hauled, mine owners laid down wooden or iron rails. On these early railroads one horse could haul as much coal as 20 horses could on ordinary roads.
Early in the 19th century came George Stephenson's locomotive and Robert Fulton's steamboat, an American invention. They marked the beginning of modern transportation on land and sea. Railroads called for the production of more goods, for they put factory-made products within reach of many more people at prices they could afford to pay.

The Condition of Labor
As conditions in industry changed, social and political conditions changed with them. Farm laborers and artisans flocked to the manufacturing centers and became industrial workers. Cities grew rapidly, and the percentage of farmers in the total population declined.
The population of England as a whole began to increase rapidly after the middle of the 18th century. Because of progress in medical knowledge and sanitation, fewer people died in infancy or childhood and the average length of life increased.
Far-reaching changes were gradually brought about in the life of the industrial workers. For one thing, machines took a great burden of hard work from the muscles of human beings. Some of the other changes, however, were not so welcome.
The change from domestic industry to the factory system meant a loss of independence to the worker. The home laborer could work whenever he pleased. Although the need for money often drove him to toil long hours, he could vary the monotony of his task by digging or planting his garden patch. When he became a factory employee, he not only had to work long hours, but he had to leave his little farm. He lived near the factory, often in a crowded slum district. He was forced to work continuously at the pace set by the machine. The long hours and the monotonous toil were an especially great hardship for the women and children. The vast majority of the jobs were held by them by 1816.
The change was particularly hard on the weavers and the other skilled workers who sank to the position of factory workers. They had been independent masters, capitalists in a small way, and managers of their own businesses. They had pride in their skill. When they saw themselves being forced into factories to do other men's bidding for the same pay as unskilled workers, it is no wonder that they rioted and broke up looms.
Problems of Capital and Labor
A person had to have a lot of capital to buy machines and open a factory. Those who were successful made huge profits with which to buy more machines, put up larger buildings, and purchase supplies in greater quantities at enormous savings. Thus capital increased far more rapidly than it ever had before. Much of it was invested in building canals, railroads, and steamships and in developing foreign trade. The men who controlled these enterprises formed a powerful new class in England--the industrial capitalists.
The capitalists had a struggle to obtain a voice in the government. They needed a better system of banking, currency, and credit. They had to find and hold markets for their products. They had many difficulties in organizing their factories to run efficiently. They also had to make a profit on their investments in the face of intense competition.
Laissez-faire was the rule in England. This meant that the government had accepted the doctrine that it should keep hands off business. Factory owners could therefore arrange working conditions in whatever way they pleased. Grave problems arose for the workers--problems of working hours, wages, unemployment, accidents, employment of women and children, and housing conditions.
Children could tend most of the machines as well as older persons could, and they could be hired for less pay. Great numbers of them were worked form 12 to 14 hours a day under terrible conditions. Many were apprenticed to the factory owners and housed in miserable dormitories. Ill-fed and ill-clothed, they were sometimes driven under the lash of the overseer. The high death rate of these child slaves eventually roused Parliament to pass laws limiting the daily toil for apprentices.
Rise of Labor Unions
Workers sought to win improved conditions and wages through labor unions. These unions often started as "friendly societies" that collected dues from workers and extended aid during illness or unemployment. Soon, however, they became organizations for winning improvements by collective bargaining and strikes.
Industrial workers also sought to benefit themselves by political action. They fought such legislation as the English laws of 1799 and 1800 forbidding labor organizations. They campaigned to secure laws which would help them. The struggle by workers to win the right to vote and to extend their political power was one of the major factors in the spread of democracy during the 19th century.

Revolution Spreads to the United States
Until 1815 France was busy with the Napoleonic wars. It had little opportunity to introduce machinery. When peace came France began to follow England. It followed slowly, however, and has never devoted itself as exclusively to manufacturing as England has. Belgium was ahead of France in adopting the new methods. The other European countries made little progress until the second half of the 19th century.
The United States too was slow in adopting machine methods of manufacture. Farming and trading were its chief interests until the Civil War. The new nation had little capital with which to buy the machinery and put up the buildings required. Such capital as existed was largely invested in shipping and commerce. Labor was scarce because men continued to push westward, clearing the forests and establishing themselves on the land.

A start in manufacturing, however, was made in New England in 1790 by Samuel Slater. An employee of Arkwright's spinning mills, Slater came to the United States in 1789. He was hired by Moses Brown of Providence, R. I., to build a mill on the Pawtucket, or Seekonk, River. English laws forbade export of either the new machinery or plans for making it. Slater designed the machine from memory and built a mill which started operation in 1790. When the Napoleonic wars and the War of 1812 upset commerce and made English products difficult to obtain, more American investors began to build factories.

Pioneer Industries and Inventions
New England soon developed an important textile industry. It had swift streams for power and a humid climate, which kept cotton and wool fibers in condition for spinning and weaving. In Pennsylvania iron for machines, tools, and guns was smelted in stone furnaces. They burned charcoal, plentiful in this forested land. Spinning machines driven by steam were operating in New York by 1810. The first practical power loom was installed at Waltham, Mass., by Francis Cabot Lowell in 1814. Shoemaking was organized into a factory system of production in Massachusetts in the early 19th century. New England was the first area in the United States to industrialize.
American inventors produced many new machines that could be applied to industry as well as to agriculture. Oliver Evans designed a steam engine more powerful than that of James Watt. Engineers quickly adopted the new engine and used it to power locomotives and steamboats.
Cyrus McCormick invented several machines used to mechanize farming. His mechanical reaper, patented in 1834, revolutionized harvesting, making it quicker and easier. Elias Howe's sewing machine eased the life of the housewife and made the manufacture of clothing less expensive.
Techniques of factory production were refined in American workshops. Eli Whitney led the movement to standardize parts used in manufacture. They became interchangeable, enabling unskilled workers to assemble products from boxes of parts quickly. American factories used machine tools to make parts. These machines were arranged in lines for more efficient production. This was called the "American system of manufacturing," and it was admired by all other industrial nations. It was first applied to the manufacture of firearms and later spread to other industries like clock and lock making.

Second Industrial Revolution
The machines of the Industrial Revolution in the 18th and early 19th centuries were simple, mechanical devices compared with the industrial technology that followed. Many new products were devised, and important advances were made in the system of mass production. Changes in industry were so great that the period after 1860 has been called the Second Industrial Revolution. New scientific knowledge was applied to industry as scientists and engineers unlocked the secrets of physics and chemistry. Great new industries were founded on this scientific advance: steel, chemicals, and petroleum benefited from new understandings of chemistry; breakthroughs in the study of electricity and magnetism provided the basis for a large electrical industry. These new industries were larger and more productive than any industries existing before. Germany and the United States became the leaders, and by the end of the 19th century they were challenging Great Britain in the world market for industrial goods.
The age of electricity began in 1882 when Thomas A. Edison introduced a system of electric lighting in New York City. Electricity was later applied to driving all kinds of machinery as well as powering locomotives and streetcars. Electric lighting quickly spread across the United States and was soon adopted in Europe. The electrical industry was dominated by large companies that developed new products and then manufactured and marketed them. These companies were based in Germany and the United States but sold their goods all over the world. They were the first multinational companies. Companies like Westinghouse and General Electric helped to electrify cities in Europe, Africa, and South America.

The steel and chemical industries used new technology that greatly increased production. The size of factories increased rapidly, employing more workers and using more machinery. These industries integrated all stages of production under a single corporate structure. They bought out competitors and acquired sources of raw materials and retail outlets. Corporations such as U.S. Steel and Standard Oil controlled all stages of manufacturing the product, from mining and drilling to delivering it to the customer. This gave them great economic power, and the United States government took measures to limit their monopolies in steel and petroleum.
The larger size of business presented great challenges to managers who administered enormous organizations with many branches and subsidiaries. Advances in communications and transportation helped decision makers to maintain control. The electric telegraph was invented by Samuel Morse in 1844 and was used to relay commercial information about prices and markets. It was used in the stock exchanges and on the railway systems. Alexander Graham Bell patented his telephone in 1876, and networks of telephone lines were built quickly across the United States.
The telephone became a useful tool for managers to keep in contact with the widely dispersed parts of their businesses. New methods of management were devised that stressed central control, planning, and efficient production methods. One of the leading advocates of "scientific management" was Frederick Winslow Taylor.

The Second Industrial Revolution marked great progress in the methods of mass production. More and more industries used interchangeable parts and machine tools. Electric power replaced steam power in factories; it was cheaper, faster, and more flexible. It allowed machine tools to be arranged more efficiently. Human power was replaced by machine power. In 1913 Henry Ford introduced the assembly line in the manufacture of his Model T Ford. Parts were assembled on a moving conveyor belt, and the Model T took shape as it moved from one work station to the next. The assembly line greatly increased the speed of manufacture and soon was used in many industries.
By the outbreak of World War I in 1914, only a small number of industries in the most industrialized nations of the world had adopted advanced production methods and organization. Much of the world had not yet begun a first industrial revolution. Russia, Canada, Italy, and Japan were just beginning to industrialize.

Only Great Britain, the United States, Germany, France, and some parts of the Scandinavian countries had successfully completed an industrial revolution. Most of the world's population still worked in primitive agricultural economies. China, India, and Spain did not begin to industrialize until well into the 20th century.
