Yerba Buena, California is renamed San Francisco, California.

Yerba Buena, a name evocative of the wild mint (specifically Clinopodium douglasii or Satureja douglasii) that grew abundantly in the area, served as the initial designation for the nascent settlement which ultimately evolved into the vibrant metropolis of San Francisco, California. Established in 1835 by Captain William Richardson, a naturalized Mexican citizen and successful entrepreneur, Yerba Buena was strategically founded as a key port and commercial hub on the eastern shore of the San Francisco Peninsula. This early establishment laid the foundational groundwork for what would become one of the world's most iconic cities, a pivotal gateway to the Pacific.

Positioned strategically near the northeastern extremity of the San Francisco Peninsula, Yerba Buena’s location was crucial for its intended purpose. It lay nestled between two significant existing Spanish colonial establishments: the Presidio of San Francisco, a military fort founded in 1776 to guard the entrance to the bay, and the Mission San Francisco de Asís (commonly known as Mission Dolores), a Franciscan mission also established in 1776, serving as a center for evangelization and agriculture. The primary intention behind founding Yerba Buena was to develop a bustling trading post and commercial entrepôt. Its superb natural deep-water harbor on San Francisco Bay made it an ideal destination for ships engaged in trans-Pacific and coastal trade, facilitating the exchange of valuable goods such as Californian hides and tallow for various manufactured imported commodities, thereby serving as a vital nexus for regional commerce during the Mexican Alta California period.

The urban design of Yerba Buena adhered to the traditional Spanish colonial town planning principles, centered around a main plaza or Plaza de Armas. This central public space, intended for civic gatherings, markets, and military parades, is remarkably preserved today as Portsmouth Square. This historic square, often referred to as the "heart" of old San Francisco, has witnessed numerous pivotal moments in the city's history. These include the first raising of the American flag in San Francisco on July 9, 1846, during the Mexican-American War, signaling the transition of California from Mexican to U.S. control, and key announcements during the transformative California Gold Rush era, such as news of major gold discoveries, forever cementing its status as a cornerstone of San Francisco’s identity and a public forum for its populace.

The transformation from Yerba Buena to San Francisco officially occurred on January 30, 1847. This renaming, orchestrated by Lieutenant Washington A. Bartlett, the first American Alcalde (magistrate and mayor) under U.S. military rule following the American conquest of California, was a strategic decision. It aimed to consolidate the identity of the rapidly growing settlement with the internationally renowned San Francisco Bay and to distinguish it more clearly from the nearby Mission San Francisco de Asís. This change effectively rebranded the burgeoning port city, aligning its name with the vast and famous bay that provided its economic lifeline and global recognition, particularly as the imminent California Gold Rush prepared to dramatically accelerate its growth and prominence.
