History and Map
Beginning in the eighteenth century, Spain established missions to colonize California and convert the American Indians to Christianity. Comandante Pedro Fages, while hunting for deserters in the Central Valley in 1772, discovered a great lake surrounded by marshes and filled with rushes; he named it Los Tules (the tules).
After Mexico achieved independence, it continued to rule California. After the Mexican Cession and the Treaty of Guadalupe Hidalgo in 1848, the area became part of the United States. Tulare County was soon formed from parts of Mariposa County only 4 years later in 1852.
