The Second Industrial Revolution, also known as the Technological Revolution, was a phase of rapid scientific discovery, standardization, mass production, and industrialization from the late 19th century into the early 20th century. The First Industrial Revolution, which ended in the middle of the 19th century, was punctuated by a slowdown in important inventions before the Second Industrial Revolution in 1870. Though a number of its events can be traced to earlier innovations in manufacturing, such as the establishment of a machine tool industry, the development of methods for manufacturing interchangeable parts, and the invention of the Bessemer process to produce steel, the Second Industrial Revolution is generally dated between 1870 and 1914 (the beginning of World War I).

The colonists during the American revolution remain divided because of political and economic purposes. Those who supported American Revolution were the Patriots. Those settlers who were against the war were called the Loyalists. The Loyalists wanted a nonviolent agreement with the British Government. Loyalists were numerous in Pennsylvania among the elite as they got benefits from the British through conducting trade.
