History of courtship in the United States
Courtship practices in the United States changed gradually throughout its history. The transition from primarily rural colonies to cities and the expansion across the continent with major waves of immigration, accompanied by developments in transportation, communication, education, industrialization, and the economy, contributed to changes over time in the national culture that influenced how young people met, interacted, and married.
