People such as John Locke, (who the colonists looked up into his writing), believed that people were born with natural rights, such as life, liberty, and property. The colonists in America believed similar, and got inspiration from what John Locke wrote in a book.
Western Europe valued imperialism. For example, Great Britain was known for the numerous colonies that they had. There is a quote that states, "The Sun never sets on Great Britain" meaning that they had so many colonies around the world that the Sun never set on them.
