History

Indigenous Peoples and Pre-Colonial Era

Long before European explorers arrived, the land now known as the United States was inhabited by numerous indigenous tribes. These Native American groups had rich cultures and societies, with complex systems of governance, trade, and spirituality. Notable tribes included the Cherokee, Navajo, Sioux, and Iroquois, among many others.

European Exploration and Colonization

In the late 15th and early 16th centuries, European explorers such as Christopher Columbus and John Cabot began to arrive in the Americas. The Spanish, French, and British established colonies throughout North America. The British colonies on the eastern seaboard eventually became the most populous and economically significant.

Independence and Nation-Building

In 1776, the Thirteen Colonies declared their independence from Britain, leading to the Revolutionary War. The war concluded with the Treaty of Paris in 1783, which recognized the sovereignty of the United States. The Constitution, adopted in 1787, established the framework for the federal government and remains the supreme law of the land.

Expansion and Civil War

Throughout the 19th century, the United States expanded westward through a combination of treaties, purchases, and conflicts, including the Louisiana Purchase, the annexation of Texas, and the acquisition of territories following the Mexican-American War. The expansion exacerbated tensions over slavery, culminating in the Civil War (1861-1865). The Union’s victory preserved the nation and led to the abolition of slavery.
