Before 1877, several significant eras occurred, including the Colonial Era (early 1600s to 1776), characterized by European settlement and the establishment of colonies in North America. This was followed by the Revolutionary Era (1775-1783), marked by the American Revolution and the fight for independence from British rule. The Early Republic Era (1783-1820) saw the formation of the United States government and the drafting of foundational documents like the Constitution. Lastly, the Antebellum Era (1820-1861) was defined by regional tensions over slavery, leading up to the Civil War (1861-1865) and the Reconstruction Era that followed.
