This was a series of economic and technological changes in the Western World 18th - 20th centuries, which brought about the extensive mechanization of production systems. This was an innovation made by James Watt in the late 18th century that greatly increased the demand for coal. This process for producing steel revolutionized the entire industry, because it allowed for cheap and fast production of large quantities. Patented in 1855, it is named for its discoverer. This name is given to the system of land ownership during the early years of the Industrial Revolution in which British landowners divided their fields into smaller units and charged rent to farmers or business owners. This device was created in the mid-1700s and was used in textile mills to greatly reduce the time it took to produce yarn. This Scottish inventor is responsible for making vast improvements to Thomas Newcomen's steam engine, the most important factor in the Industrial Revolution. He was a wealthy, 19th century English industrialist and imperialist who founded De Beers diamonds and later established a colony in Africa (that eventually became known as Zimbabwe)
