What role does religion play in European immigration to the United States?

In fact, in 1620, the Mayflower, Britain's first ship to the United States, was a group of Puritans who sailed to the United States to avoid religious persecution and established the first colony in North America, and later established the United States through the North American War of Independence. Before the formation of the country and the American nation, religion played a role in uniting people everywhere, so in this sense, religion played a cohesive role in the process of European immigration to the United States.
