Citizenship and Migration Developed through Different Histories
The Treaty of Guadalupe Hidalgo ended the U.S.-Mexico War and shifted control over existing Mexican and Indigenous communities. Land law, courts, violence, and settlement shaped property and power. Later Mexican migration expanded during revolution and labor demand. During the Depression, officials pressured or removed people of Mexican descent, including U.S. citizens. Puerto Rico’s history followed colonial war and territorial rule, not immigration. Congress extended statutory U.S. citizenship in 1917, yet island residents lack voting representation in Congress and do not vote for president while residing there. Cuban, Dominican, Central and South American, and Caribbean communities arrived through distinct combinations of work, family, revolution, dictatorship, U.S. policy, asylum, and refugee rules. National origin, race, class, status, language, and generation produced varied experiences
