Founded in 1812 on the Northern California coast, Fort Ross was a Russian colonial outpost that served until 1841 as the center of the southernmost Russian settlements in North America. Built within Kashaya Pomo territory at Metini, it became the first multi-ethnic community north of the Spanish missions in what is now the United States. Established to supply Russian Alaskan colonies and support the maritime fur trade, it grew into a regional hub with a port and inland ranches. Fort Ross also introduced early technologies to Alta California and reflects a brief but distinctive period when Russian ambitions overlapped with Spanish, British, American, and Mexican interests.
