He waged war against Mexico. This conflict is known as the Mexican-American War (1846-1848).
Mexican-American War
The year that California became a territory was around 1848 after the Mexican-American War. It became a state in 1850.
The manifest destiny was the United States should stretch from the Atlantic to the Pacific. This was realized during the Polk administration when the US annexed California and the Mexican territory in between.
The three main points of the Comprise of 1850 were; 1.California as a free state including Southern California 2.Utah Territory and New Mexico Territory with slavery to be decided by popular sovereignty. 3.The slave trade was abolished in Washington, DC (but not slavery itself), and the Fugitive Slave Act was strengthened.

Mexican-American War
After the Mexican-American War, the whole territories of California were split on Alta California (Upper California) which corresponds to the present-day US state of California, and Baja California (Lower California) which corresponds to the peninsula of the same name. It became the territory of Baja California for the following 80 years, until 1930 when the Mexican Congress decided to split up such territory in two: the North Territory of Baja California (Territorio Norte de Baja California) and South Territory of Baja California (Territorio Sur de Baja California), being divided by the 28th parallel.Years later in 1951, Mexican president Miguel Aleman Valdes announced that the North Territory of Baja California satisfied the conditions required by the Constitution to be admitted as a free and sovereign state: population and economic ability to survive without federal support. The new state was named as Estado Libre y Soberano de Baja California (English: Free and Sovereign State of Baja California).Finally, in 1974 Mexican President Luis Echeverria Alvarez pushed a bill for the South Territory of Baja California to be elevated to the category of state.
