Battle of Santa Rosa

About

In the 19th century, Nicaragua was beset by political issues among liberals and conservatives, allowing William Walker, an American Southerner seeking to establish English-speaking slavery states in Latin America, to ascend to the Nicaraguan presidency.

Walker believed in the doctrine of manifest destiny, and established himself in Nicaragua in the guise of offering help to liberals , but his real intentions were to conquer the five provinces of Central America, a manifesto he titled "Five or None." This territory claimed by Nicaragua was part of Costa Rica, creating a territorial issue that, together with the fear of an all-out invasion of the region, led to the Filibuster War or Campaña Nacional between both countries from 1855 to 1857.
