Swami Vivekananda visited the USA twice. His first visit (1893-1896) included his famous speech at the World's Parliament of Religions in Chicago (1893) and the founding of the Vedanta Society of New York (1894). His second visit was from 1899 to 1900. During this second visit, he spent significant time on the West Coast and was instrumental in starting activities that led to the establishment of Vedanta Centres in San Francisco and Southern California (Los Angeles area). While the formal incorporation dates for some centres might be 1900, the activities leading to their establishment were initiated by Vivekananda during his 1899-1900 visit. Therefore, San Francisco and Los Angeles are the places among the options where Vedanta Centres were set up or initiated during his 1899 visit period.
