The first Buddhists to arrive in North America were Chinese immigrants to the West Coast in the 1848 Gold Rush. By 1875 there were 8 temples in San Francisco and many more smaller ones along the West Coast. They practiced a mixture of "Confucian ancestor veneration, popular Taoism, and Pure Land Buddhism." At about the same time, immigrants from Japan began to arrive as laborers on Hawaiian plantations and central-California farms. In 1893 the first Jōdo Shinshū priests arrived in San Francisco, and they formally established the Buddhist Missions of North America, later renamed the Buddhist Churches of America in 1899. The BCA is the oldest major institutional form of Buddhism in the United States. This organization acted as way for immigrants to preserve their Japanese culture and language as well as their religion.
