In 1821, as a result of the Adams-Onís Treaty negotiated in 1819, the province of East Florida was ceded from Spain to the United States. On November 5, 1821, during the transfer proceedings in St. Augustine, North American representatives certified that they had received a series of documents, a transaction that was affirmed by Spanish royal notary Juan de Entralgo. 1 In doing so, United States commissioners acquired the official archives relating to the Spanish administration in East Florida from 1784 to 1821, a time designated by historians as the Second Spanish Period.2 Collectively, these documents have come to be known as the East Florida Papers.
