How was Liberia started?

Liberia was established by the citizens of United States as a colony for former African-American slaves. It is one of the two sovereign states in the world that were started by a citizen of a political power as a colony for former slaves of the same political power. Historians believe that many of the indigenous peoples of Liberia migrated there from the north and the east between 12th and 16th centuries AD. Portuguese explorers established contact with the people of the land later known as "LIBERIA" as early as 1461. They named the area Costa da Pimenta ( Pepper Coast ) because of the abundance of melegueta pepper. In 1602 the Dutch established a trading post at Grand Cape Mount but destroyed it in a year later. 1663, the British installed trading posts on the Pepper Coast. No further known settlements by non- African colonists occurred along the Grain Coast (an alternative name ) until the arrival 1821 of free blacks from the United States.
