For hundreds of years, Portuguese explorers have swept across the globe, many of them landing in California in the 1840s as whalers, ship jumpers, and Gold Rush immigrants. Gold was the lure, but land was the anchor. San Jose became home to Portuguese immigrants who overcame prejudice to contribute to the area politically, socially, and economically. They worked hard, transplanting farming, family, and festa traditions while working in orchards and dairies. Many came from the Azores Islands, 800 miles out to sea from mainland Portugal. For over 160 years, the Portuguese have enriched San Jose with colorful figures, including radio star Joaquim Esteves; jeweler and filmmaker Antonio Furtado; the charismatic and controversial Fr. Lionel Noia; educator Goretti Silveira; and community leaders Vicki and Joe Machado.

In a centurys time, Portuguese explorers had discovered two-thirds of the world. In 1542, Joao Rodrigues Cabrilho uncovered the west coast of America when he sailed into a large bay sheltered by a beautiful peninsula that would someday be known as Point Loma. By the 20th century, a small group of Portuguese immigrants had settled in the La Playa area in pursuit of a life on the sea. They brought their unique traditions and folklore customs, built churches and halls, and celebrated with Holy Spirit Festas in the streets of their new homeland. Today 19,717 make up San Diegos Portuguese community, where many of them still live in Point Loma.

Since the founding of California's El Pueblo de San JosAA(c) de Guadalupe in 1777, people of Mexican ancestry have contributed to make San JosAA(c) a rich cultural, political, and economic epicenter. Mexican miners who worked in the local mines helped San JosAA(c) become one of the top mercury producers in the world. In the 20th century, Mexicans labored in the "Valley of Heart's Delight," as the Santa Clara Valley region was called, picking, canning, drying, and packaging fruits and vegetables for America's dinner table. They paid homage to their cultural heritage as they formed ballet folklAA3rico groups, established mariachi bands, painted murals, and wrote literature. Through grassroots organizing and collective action, countless heroines and heroes, such as labor leader Cesar Chavez, dedicated their lives to improving conditions in their neighborhoods and communities. In 1999, the City of San JosAA(c) acknowledged the contributions of Mexicans with the grand opening of the Mexican Heritage Plaza, a cultural center for the performing arts.
