The Mexican-American War ended in 1848 when Mexico ceded much of its northern territory to the United States. The Treaty of Guadalupe Hidalgo granted citizenship to Mexicans who remained in the ceded territories, but this led to significant social and cultural changes that affected the life of Mexicanos.
One of the most significant social changes was the loss of land and property. Mexicans who lived in the areas ceded to the United States saw their land, homes, and other properties confiscated or taken by force. Many were forced to leave their homes and become refugees or laborers on their former lands.
Mexicanos also faced discrimination and social marginalization in the newly created territories. They were often treated as second-class citizens and faced discrimination in employment, education, and other aspects of life. Racist attitudes towards Mexicans were widespread, and many were subjected to violence and mistreatment.
Culturally, Mexicanos retained many of their traditions and customs, despite living in a new country. They continued to speak Spanish, practice Catholicism, and celebrate traditional Mexican holidays and festivals. However, their culture was impacted by the dominant American culture, and many began to integrate more into American society.
Overall, the Mexican-American War had a significant impact on the lives of Mexicanos, including the loss of land and property, social and cultural marginalization, and assimilation into American culture. Despite these challenges, Mexicanos remained resilient and maintained many of their traditions and cultural values, contributing to the rich diversity of American society.
