Cabrillo Reaches San Diego Bay
Portuguese explorer Juan RodrÃguez Cabrillo, sailing under the Spanish flag from Navidad in Mexico, sought the mythical Strait of Anian while charting the Pacific coast. Departing in June 1542 with three ships, his expedition navigated northward along uncharted waters for over three months. On September 28, 1542, Cabrillo's fleet entered what he named San Miguel Bay, now known as San Diego Bay, becoming the first documented Europeans to reach the California coast. He claimed the territory for Spain and noted its excellent harbor qualities before continuing north. The voyage provided the earliest European descriptions of Alta California's coastline and indigenous populations.
Why it matters: Cabrillo's landing initiated sustained Spanish interest in the region, paving the way for later colonization, missions, and the integration of California into the Spanish Empire and eventually the United States. It represents a key milestone in the European exploration and mapping of the North American Pacific coast.
