History
The history of the United States began with the arrival of indigenous peoples from Asia thousands of years ago. In the 16th century, European explorers, including Christopher Columbus and Henry Hudson, arrived on the continent, leading to the establishment of colonies by various European powers. The American Revolution (1775-1783) saw the Thirteen Colonies gain independence from Great Britain, forming the United States of America. The country expanded westward through the Louisiana Purchase of 1803 and the Mexican-American War (1846-1848), becoming a continental power. The Civil War (1861-1865) was a pivotal moment in American history, resulting in the abolition of slavery and a more unified federal government.
20th and 21st Centuries
The United States emerged as a global superpower in the 20th century, playing a significant role in both World War I and World War II. The Cold War with the Soviet Union dominated international relations from the 1940s to the 1990s. In the 21st century, the United States has continued to face global challenges, including terrorism, economic crises, and environmental issues. The 9⁄11 attacks in 2001 led to the War on Terror, while the Great Recession of 2008 had profound economic implications. Today, the United States remains a leading world power, with ongoing debates about its role in international affairs, economic policy, and social justice.
