Following its victory against the British in the Revolutionary War, the United States was plagued by a variety of internal problems. The weak central government could not raise taxes to cover war debts and was largely unable to pass legislation. Many early American politicians and thinkers believed that these issues were the result of the Articles of Confederation, the first governing document of the United States. In 1787 a convention gathered in Philadelphia to attempt to amend it. Soon, however, the gathering shifted its focus to constructing a newer and more powerful Constitution for the fledgling country. Two main competing factions emerged, the Federalists and the anti-Federalists. The former supported a more powerful central government while the latter opposed it.
