The prehistory of the Americas (North, South, and Central America, and the Caribbean) begins with people migrating to these areas from Asia during the height of an Ice Age. These groups are generally believed to have been isolated from peoples of the "Old World" until the coming of Europeans in the 10th century from Norway and with the voyages of Christopher Columbus in 1492.
The ancestors of today's American Indigenous peoples were the Paleo-Indians; they were hunter-gatherers who migrated into North America. The most popular theory asserts that migrants came to the Americas via Beringia, the land mass now covered by the ocean waters of the Bering Strait. Small lithic stage peoples followed megafauna like bison, mammoth (now extinct), and caribou, thus gaining the modern nickname "big-game hunters." Groups of people may also have traveled into North America on shelf or sheet ice along the northern Pacific coast.
Cultural traits brought by the first immigrants later evolved and spawned such cultures as Iroquois on North America and Pirahã of South America. These cultures later developed into civilizations. In many cases, these cultures expanded at a later date than their Old World counterparts. Cultures that may be considered[citation needed]advanced or civilized include Norte Chico, Cahokia, Zapotec, Toltec, Olmec, Maya, Aztec, Chimor, Mixtec, Moche, Mississippian, Puebloan, Totonac, Teotihuacan, Huastec people, Purépecha, Izapa, Mazatec, Muisca, and the Inca.
After the voyages of Christopher Columbus in 1492, Spanish, Portuguese and later English, French and Dutch colonial expeditions arrived in the New World, conquering and settling the discovered lands, which led to a transformation of the cultural and physical landscape in the Americas. Spain colonized most of the American continent from present-day Southwestern United States, Florida and the Caribbean to the southern tip of South America. Portugal settled in what is mostly present-day Brazil while England established colonies on the Eastern coast of the United States, as well as the North Pacific coast and in most of Canada. France settled in Quebec and other parts of Eastern Canada and claimed an area in what is today the central United States. The Netherlands settled New Netherland (administrative centre New Amsterdam - now New York), some Caribbean islands and parts of Northern South America.
European colonization of the Americas led to the rise of new cultures, civilizations and eventually states, which resulted from the fusion of Native American and European traditions, peoples and institutions. The transformation of American cultures through colonization is evident in architecture, religion, gastronomy, the arts and particularly languages, the most widespread being Spanish (376 million speakers), English (348 million) and Portuguese (201 million). The colonial period lasted approximately three centuries, from the early 16th to the early 19th centuries, when Brazil and the larger Hispanic American nations declared independence. The United States obtained independence from England much earlier, in 1776, while Canada formed a federal dominion in 1867. Others remained attached to their European parent state until the end of the 19th century, such as Cuba and Puerto Rico which were linked to Spain until 1898. Smaller territories such as Guyana obtained independence in the mid-20th century, while certain Caribbean islands remain part of a European power to this day.
Harappan civilization forms an important landmark in the prehistory of the Indian subcontinent. The civilization offers an excellent example to the modern world in various ways. Their expertise in town planning, water management and harvesting systems as well as drainage mechanism is unparalleled.
What does it mean to be a Progressive? Simply put, Progressives advocate change or reform. Politically speaking, Progressives believe that the government should be responsive to the needs of its citizens in order to improve conditions in government and society. During the Progressive Era, from around 1900-1917, reformers sought to end abuses of power in politics and government.
Local Political Reforms
Many large cities were controlled by political machines, which were organizations that controlled the activities of a political party. Under city bosses, political machines were able to corrupt the city governments by bribing judges, providing contracts to businessmen in return for favors, and filling city jobs with political supporters, regardless of their qualifications. Special interest groups, such as labor unions and trade associations, lobbied for reform and stood up to the power of the political machines. Sometimes the political machines took on reforms themselves in order to maintain influence and keep their organizations in operation.
