I never realized how large the California territory was when Spain and then Mexico claimed the land. The region called Californias stretched past the Sierra Nevada Mountains and across the current states of Utah, Nevada, New Mexico, as well as some of Arizona. Baja California was also part of this area. The Republic of Mexico governed Nuevo Mexico and Tejas (or Texas) as well. This land fit like puzzle pieces next to what is now known as the Louisiana Purchase, which the United States purchased from France. The United States annexed the Mexican territories of Alta California and Nuevo Mexico after the Mexican-American War in the 1840s. Texas had become a republic but then joined the States as well. The United States actually compensated Mexico for these territories — a highly unusual action at the time for a victor in a war.
Who built the first white man’s residence in San Francisco and where was it?
In earlier years, there was much debate about who built the first dwelling in San Francisco, but the City of San Francisco finally decided the honor belonged to Captain William A. Richardson. In the 1800s, the city of San Francisco was known as Yerba Buena. The Republic of Mexico governed Alta California, and its governor José Figueroa asked Richardson to establish a pueblo at Yerba Buena. In 1835 he built a tent-shanty in which he and his family lived for four months. Richardson then built a wood plank house on a lot that he purchased from the Mexican government for $25. The California Historical Society confirmed that the lot was on the corner of the San Francisco streets of Grant and Clay. The pictured plaque that hangs on the current house says: “The Birthplace of a Great City — Here, June 25, 1835, William A. Richardson, founder of Yerba Buena (later San Francisco) erected its first habitation, a tent dwelling, replacing it in October, 1835, by the first wooden house, and on this ground in 1836, he erected the large adobe building, known as ‘Casa Grande.’ This tablet was placed under the auspices of the Northern Federation of Civic Organizations of San Francisco.” I want to thank my friend Stephanie Sigue for photographing this plaque for me. For a marker of such a momentous event, it is hard to find and obscured from casual viewing, but look carefully and you will find it.
