During his lifetime, many Americans believed in Manifest Destiny. This was the doctrine that the United States should expand its territory across the continent. Walker used this idea to justify his actions as a filibuster. Filibustering was the practice of organizing unauthorized military expeditions into foreign lands. His goal was to establish new colonies and expand American influence. These actions often ignored the laws of the countries he entered.

Walker's early life was marked by intense academic and professional achievement. He graduated from the University of Nashville at the age of 14. In 1843, he earned a medical degree from the University of Pennsylvania. He later studied medicine in Edinburgh and Heidelberg. After practicing medicine, he moved to New Orleans to study law. He also worked as an editor for The Daily Crescent, a liberal newspaper. However, his life took a dramatic turn after the death of a woman named Helen Martin. This event led him to develop a reckless disregard for life.

In the early 1850s, Walker moved to San Francisco to work for the San Francisco Herald. This period was defined by the rise of filibustering groups in California. These groups were often supported by the Knights of the Golden Circle. This was a secret society that wanted to expand slavery. Walker himself became involved in these violent activities. He even fought three duels with pistols, wounding him in two of them. One notable duel occurred on January 12, 1851, against a gunman named William Hicks Graham.

Walker first attempted to seize territory in Mexico. In 1853, he traveled to Guaymas to ask for permission to start a colony. He claimed his colony would protect U.S. soil from raids. The Mexican government refused his request. Undeterred, Walker recruited supporters from Tennessee and Kentucky. On October 15, 1853, he led forty-five men to conquer parts of Baja California and Sonora.

He captured La Paz and declared a new Republic of Lower California. He named himself president and applied Louisiana laws to the region. This allowed slavery to become legal in his territory. However, strong resistance from Mexican forces forced him to retreat to California.

Walker's most significant campaign took place in Nicaragua starting in 1855.

At the time, Nicaragua was in a civil war between the Legitimist Party and the Democratic Party. The Democratic Party hired Walker and his mercenaries to help them. Walker arrived with sixty men and eventually took control of the country. By July 1856, he had established himself as the president of Nicaragua.

His regime was even recognized by U.S. President Franklin Pierce. Walker used his power to relegalize slavery in Nicaragua. He wanted to create a society dominated by white people.

Walker's presidency faced intense opposition from several powerful entities. He took control of the Accessory Transit Company, which was owned by tycoon Cornelius Vanderbilt. This move made Vanderbilt a major enemy. Additionally, the British Empire viewed Walker as a threat to its interests in a potential Nicaragua Canal. A military coalition led by Costa Rica eventually fought against him. This coalition defeated Walker's forces and forced his resignation on May 1, 1857.

His actions had caused great instability in the region.

After losing power, Walker tried to start new military projects. He sought support from pro-slavery forces in the Southern United States. In 1860, he published a book called The War in Nicaragua. This book promoted the idea of conquering Central America to expand slavery. Later that year, he returned to Central America to continue his efforts. The British Royal Navy arrested him and handed him over to the government of Honduras. He was executed by the Honduran government in 1860.
