Mexican American history encompasses the experiences and contributions of people of Mexican descent in the United States. This history began long before the U.S. was established, as many Mexican communities existed in territories that later became part of the U.S. after the Mexican-American War in 1846-1848. Throughout the years, Mexican Americans have played significant roles in various aspects of American life, including culture, politics, and labor. Key events, such as the Chicano Movement in the 1960s, sought to address civil rights and social justice issues, highlighting the ongoing struggle for equality and recognition within American society.
