California was the name given to the Mexican possessions on the Pacific coast north of Mexico itself. There were now many American settlers there, especially at Monterey. Hearing of the outbreak of the Mexican War, they Set up a republic of their own. Their flag had a figure of a grizzly bear painted on it, and hence their republic is often spoken of as the Bear Republic. Commodore Stockton with a small fleet was on the Pacific coast. He and John C. Frémont assisted the Bear Republicans until soldiers under Colonel Kearney reached them from the United States by way of Santa Fé. THE BEAR FLAG.

The direct cause of the Mexican War was Mexico's unwillingness to give up Texas without a struggle. But the Mexicans had treated many Americans very unjustly and owed them large sums of money. A treaty of peace was made in 1848. Mexico agreed to abandon her claims to Texas, California, New Mexico, Nevada, Utah, and Colorado. The United States agreed to withdraw its armies from Mexico, to pay Mexico fifteen million dollars, and to pay the claims of American citizens on Mexico. These claims proved to amount to three and one-half million dollars, In the end, therefore, the United States paid eighteen and one-half million dollars for this enormous and exceedingly valuable addition to its territory.
