About California Admission Day

In 1849, leaders from around the future state of California drafted California’s first constitution, which was approved on November 13 that year by a vote of 12,064 to 811. In January, 1850, the State Legislature began its first two-year session. On September 9, 1850, California became the 31st entry into the Union.

On September 9, 1924, California’s “Bear Flag” flew over the White House to honor the date of California’s admission. In 1984, however, Governor George Deukmejian signed legislation changing its observance to a “personal” option. In recent times, Californian governors have made public proclamations, inviting the public to observe the day.
