BRIEF HISTORY OF SAN BERNARDINO
In 1850, when the first California legislature met to divide the new State of
California into its original 27 counties, the area that would become San
Bernardino County was then in the huge San Diego County. A year later, it
became part of the expanding Los Angeles County. But in April, 1853, a bill
was introduced to divide off the eastern portion of Los Angeles County - and San Bernardino County was born.
