William Walker, an American journalist and mercenary, departed San Francisco in May 1855 to intervene in Nicaragua's civil war. Leading a force of approximately sixty men, he supported the Democratic Party against the Legitimist government. His expedition marked the beginning of the Filibuster War, a conflict that would escalate into a broader regional struggle involving Central American nations.

Background and detail

Background. In 1854, a civil war erupted in Nicaragua between the Legitimist Party, based in Granada, and the Democratic Party, based in León. The Democratic Party, led by Francisco Castellón, launched a rebellion against President Fruto Chamorro. Walker, motivated by earlier filibustering projects, agreed to lead a mercenary army employed by the Nicaraguan Democratic Party to fight against the Legitimists.

Expedition. Walker sailed from San Francisco on May 3, 1855, with approximately sixty men. His force arrived in Nicaragua in June 1855, landing at El Realejo. This intervention was part of a broader pattern of American adventurer activities, following his failed attempt to conquer Sonora in 1853–54, which had resulted in a trial in San Francisco.

Political Context. The conflict was fueled by political tensions, including a constitutional amendment in April 1854 that increased presidential term lengths. Walker's presence in Nicaragua was initially supported by the Democratic Party. However, the situation escalated when Costa Rica declared war on Walker's government in early 1856, marking the transition from a civil war to a broader regional conflict known as the Filibuster War.
