York styles itself the first Capital of the United States, although historians generally consider it to be the fourth capital, after Philadelphia, Baltimore and (for one day) Lancaster.[13] The claim arises from the assertion that the Articles of Confederation was the first legal document to refer to the colonies as "the United States of America".[14] The argument depends on whether the Declaration of Independence, which also uses the term, would be considered a true legal document of the United States, being drafted under and in opposition to British rule.
