• Mexican–American War (1846–48): Mexico lost half its territory; many displaced Mexicans moved north.
• Gold Rush (1849): Drew thousands, including Mexicans, seeking fortune.
• Cultural Ties: California was Mexican until 1848; existing connections eased migration.
• Political Instability: Mid-century turmoil in Mexico pushed refugees north.
• Land Grants: Mexican rancheros defended Spanish/Mexican land claims in California courts.

Ongoing Economic Factors

• Agricultural Labor: California's farms needed workers; Mexican labor filled demand.
• Industrial Jobs: Railroads, construction, urbanization created more opportunities.
