Progressive EraThe Progressive Era (1896–1917) was a period of widespread social activism and political reform across the United States focused on defeating corruption, monopoly, waste, and inefficiency. The main themes ended during American involvement in World War I (1917–1918) while the waste and efficiency elements continued into the 1920s. Progressives sought to address the problems caused by rapid industrialization, urbanization, immigration, and political corruption; and by the enormous concentration of industrial ownership in monopolies.
American frontierThe American frontier, also known as the Old West, popularly known as the Wild West, encompasses the geography, history, folklore, and culture associated with the forward wave of American expansion in mainland North America that began with European colonial settlements in the early 17th century and ended with the admission of the last few contiguous western territories as states in 1912. This era of massive migration and settlement was particularly encouraged by President Thomas Jefferson following the Louisiana Purchase, giving rise to the expansionist attitude known as "Manifest Destiny" and the historians' "Frontier Thesis".
Aaron BurrAaron Burr Jr. (February 6, 1756 – September 14, 1836) was an American politician and lawyer who served as the third vice president of the United States from 1801 to 1805 during Thomas Jefferson's first presidential term. His legacy is defined by his famous personal and political conflict with Alexander Hamilton, which culminated in the Burr–Hamilton duel in Weehawken, New Jersey on July 11, 1804, during which Burr mortally wounded Hamilton, who died from his wounds the following day.
Territorial evolution of the United StatesThe United States of America was formed after thirteen British colonies in North America declared independence from the British Empire on July 4, 1776. In the Lee Resolution, passed by the Second Continental Congress two days prior, the colonies resolved that they were free and independent states. The union was formalized in the Articles of Confederation, which came into force on March 1, 1781, after being ratified by all 13 states. Their independence was recognized by Great Britain in the Treaty of Paris of 1783, which concluded the American Revolutionary War.
PhysiocracyPhysiocracy ( physiocratie; from the Greek for "government of nature") is an economic theory developed by a group of 18th-century Age of Enlightenment French economists who believed that the wealth of nations derived solely from the value of "land agriculture" or "land development" and that agricultural products should be highly priced. Their theories originated in France and were most popular during the second half of the 18th century. Physiocracy became one of the first well-developed theories of economics.
Political realignmentA political realignment, often called a critical election, critical realignment, or realigning election, in the academic fields of political science and political history, is a set of sharp changes in party ideology, issues, party leaders, regional and demographic bases of power of political parties, and the structure or rules of the political system, such as voter eligibility or financing. The changes result in a new political power structure that lasts for decades, replacing an older dominant coalition.
