The American adventurer William Walker conquers Nicaragua.
William Walker (May 8, 1824 September 12, 1860) was an American physician, lawyer, journalist and mercenary who organized several private military expeditions into Mexico and Central America with the intention of occupying the local nations and establishing slave-hold colonies, an enterprise then known as "filibustering". Walker usurped the presidency of Nicaragua in July 1856 at the request of Liberal Democratic Party of Nicaragua and ruled until May 1, 1857, when he was forced out of the presidency and the country by a coalition of Central American armies. He returned in an attempt to re-establish his control of the region, but was captured and executed by the government of Honduras in 1860 while escaping the Costa Rican army after being defeated by General Caas in the battles of Rivas and Santa Rosa.
An adventure is an exciting experience or undertaking that is typically bold, sometimes risky. Adventures may be activities with some potential for physical danger such as traveling, exploring, skydiving, mountain climbing, scuba diving, river rafting or participating in extreme sports. Adventures are often undertaken to create psychological arousal or in order to achieve a greater goal such as the pursuit of knowledge that can only be obtained in a risky manner.
