The culture of the United States began as the culture of its first English colonists. The culture quickly evolved as an independent frontier culture supplemented by indigenous and Spanish–Mexican cowboy culture and by the cultures of subsequent waves of immigrants, first from Europe and Africa and later from Asia. Overall, significant cultural influences came from Europe, especially from the German, English and Irish cultures and later from Italian, Greek and Ashkenazi cultures. Descendants of enslaved West Africans preserved some cultural traditions from West Africa in the early United States. Geographical place names largely reflect the combined English, Dutch, French, Spanish, and Native American components of U.S. American history.[67]

There are two dominant sociological models of cultural assimilation. The traditional melting pot model describes a form of homogenization. Immigrants from other cultures bring unique cultural aspects which are incorporated into the larger American culture, but then the immigrant populations gradually adopt the unified culture, forming a single "alloy". A more recently articulated model is that of the salad bowl, in which immigrant cultures retain some of the unique characteristics. Instead of merging with a unified American culture, they intermingle, forming a heterogeneous mixture, not unlike a salad composed of different vegetables.[95][67] There is considerable contemporary political debate over the merits of cultural assimilation versus pluralism or multiculturalism.

An important component of American culture is the American Dream: the idea that, through hard work, courage, and self-determination, regardless of social class, a person can gain a better life.[96]
