During Spanish colonial rule in Mexico, large estates called haciendas emerged on land seized from indigenous peoples. The Spanish landowners, or conquistadors, forced Native Americans to work on the haciendas for low wages and stripped them of most of their land. This system established social castes based on race that determined one's status. After independence, conservative elites who wanted to maintain the colonial system clashed with liberals seeking land reform and greater rights for indigenous Mexicans and mestizos. The legacy of colonial land seizures and inequality continued to shape conflicts over land and political power in independent Mexico.
