How America Became the USA?

In the Name of Allah---the Most Beneficent, the Most Merciful.

American history began with the arrival of European explorers, notably Christopher Columbus in 1492, followed by Spanish, French, and English colonization. The British established 13 colonies along the Atlantic coast during the 17th and 18th centuries. Tensions over taxation and governance led to the American Revolution (1775–1783), during which the colonies declared independence in 1776 through the Declaration of Independence. After defeating Britain in the war, the colonies united under the U.S. Constitution in 1789, forming the United States of America — a new republic committed to democratic ideals, territorial expansion, and self-governance. Let’s discover how America became the USA.
