The Donation of Constantine was a medieval document that described how Emperor Constantine gave Pope Sylvester I (314-35) primacy over all other churches, including Constantinople. The papacy employed this document to support its claims of jurisdiction over the entire church. The Eastern church never quite bought it, and for good reason: in the fifteenth century, the document was proved a forgery.
