In 1846, William B. Ide, a California settler, established the California Bear Republic. After a revolt called the Bear Flag Revolt, Ide and other settlers seized Sonoma pueblo, captured Mariano Guadalupe Vallejo, and proclaimed the land to be the California Republic. The repbulic, however, only last just over 20 days because the United States took possession of California from Mexico. Today, visitors can see the park, an old adobe home, and a visitors center to learn about the lives of early settlers in California.

William B. Ide (1796-1852) was a pioneer who established the California Bear Republic in 1846, which lasted for just over 20 days. Ide and his family moved westward through the 1840s until he arrived in Alta California, which was then a providence of Mexico. In 1846, however, the Mexican government wanted to expel all non-Mexican settlers. Ide and other settlers seized the Sonoma pueblo in June 1846. Ide and his group also captured Mariano Guadalupe Vallejo, the Mexican Commandante of Northern California. This became known as the Bear Flag Revolt. The day after the revolt on June 15, Ide released his his proclamation, which, on June 17, raised the California Bear Flag. This proclaimed the land to be the California Republic. The Bear Flag Republic lasted until July 9, 1846, when the United States took possession of California from Mexico.

Visitors at the park today can learn about the California pioneers. The park has an old adobe home, as well as a blacksmith shop. There, visitors can learn about the activities of the early California pioneers.
