The document discusses immigration to the United States in the late 19th/early 20th century. During this period, most immigrants came from southern and eastern Europe as well as the eastern Mediterranean rather than previous sources of northern Europe. People left these areas due to overpopulation, lack of jobs, and mistreatment by governments. America offered jobs, opportunity, and freedom. Many immigrants passed through Ellis Island where they underwent health screenings and processing before settling across the United States, often where family or jobs were located.
