The Republic of Baja California was a proposed state from 1853 to 1854, after American private military leaderWilliam Walker failed to invade Sonora from Arizona. Walker wanted to appropriate Sonora, and his claims had both the support of tycoons and government complacency in the United States. In November 1853 he set off with two hundred men to La Paz, where he captured the political head and proclaimed the independence of the Republic of Baja California, a state that never had recognition nor truly existed because Walker had neither full control of the peninsula nor the support of the population. He faced resistance from the Mexican army and from civilians, among them a group led by. In spite of being replicated in Ensenada and suffering the mutiny of his US troops, Walker declared himself president of the Republic of Sonora, which also included Baja California, and, like his successor, was not there in fact or endorsement. In fact, Walker reached Sonora only in 1854 and when pressured by the US Navy had to flee to Ensenada, Mexico. In the face of Melendrez's harassment and the desertion of more troops, Walker and the remnants of his filibuster army surrendered to the US military in San Diego. Brought to trial, the judge said he was guilty of violating the Neutrality Act signed between Mexico and the United States after the US invasion of Mexico in 1847. However, Walker was acquitted by the jury.
History
William Walker was an American physician and adventurer who settled in California during the gold rush. He had tried to take over the state of Sonora before launching the campaign against Baja California, with the support of American moguls. Walker left California with 45 American mercenaries on October 17, 1853, with the intention of arriving at Guaymas, and occupying the Mexican state. However, one year before, the Mexicans had already repelled an expedition of French filibusters, increased their troops and had military preparedness. Perhaps this made Walker refrain. He chose to first attack and take the Baja California peninsula as a first step to seize Sonora. Aboard the schooner Caroline, Walker's expedition arrived at Cabo San Lucas on October 28 of that year. He moved by sea to La Paz, capital of Baja California territory, which he occupied five days after the capture of Rafael Espinosa, political head of the territory. There, the filibusters hauled down the Mexican flag and hoisted in place a flag of three horizontal stripes, two red and a white center, with two stars representing Baja California and Sonora. On November 3, 1853, the mercenaries proclaimed the independence of the peninsula which they called the Republic of Baja California. Later, the expedition captured Colonel Juan Clímaco Rebolledo, who came to replace Espinosa in the office of a political leader without knowing that the capital of Baja California had been seized by the American invaders. Since the expedition of reinforcements from California were slow in coming, Walker decided to move its headquarters to the north of the peninsula, near the border with U.S. and the land passage to Sonora, which was the goal of their ambitions and also the US government, which had already expressed its intention to buy northwestern Mexico. In La Paz, there were some clashes between civilian residents and filibusters, Walker played as military victories over the Mexican government, which he accused of being tyrant and decadent. And in Ensenada, the filibusters established their headquarters in what is now the Third and Gastélum streets of that city From there, Walker issued a proclamation to the American people, requesting their support to defend the independence of Baja California, which had a self-appointed president. Many American volunteers joined the call of Walker, to add a number of 253 climbers who arrived in Ensenada on the boat Anita.
