The American Revolutionary War (1775-1783) saw the emergence of a national identity for America against British rule. Americans began to unite under the shared goal of independence, leading to a distinct sense of nationality and self-governance. The struggle was characterized by widespread opposition to British taxation and governance, encapsulated in slogans like "no taxation without representation." The Declaration of Independence in 1776 further solidified this identity by articulating the principles of liberty and democracy. This conflict fostered a sense of unity among the colonies and laid the foundation for the development of American civic values and national identity.
