Birth of the Republican Party in California

The Territory of California, ceded to the United States by the Treaty of Guadalupe Hidalgo in 1848, adopted a Constitution which was ratified on November 1849. It outlawed slavery and, as a result, Federal recognition of California’s status was blocked for over a year by Southern congressmen. Finally, in September 1850, President Fillmore signed the Bill which made California a free state, as called for by the Compromise of 1850. The paramount issue of slavery is reflected in the document, which formally established the California State Anti-Slavery party, called “The Republican Party”.
