Papal States–United States relations

Relations between the Papal States and the United States date back to the American Revolution when the first official contact between both countries occurred in 1784. Formal relations weren't established until 1848. Diplomatic relations ceased in 1870 when the Papal States were incorporated into the Kingdom of Italy.

History

The Papal States recognized the United States on December 15, 1784, when American representatives in Paris were approached by the papal nuncio and told that the Papal States "opened the ports of Civita Vecchia on the Mediterranean and Ancona on the Adriatic, to the ships of the young republic of America."

In a message to the United States Congress on December 7, 1847, President James K. Polk proposed to recognize the Papal States which resulted in funding by Congress to fund appointing a Chargé d’Affaires to the Papal States. 50 years earlier, Congress established a consulate in Rome in 1797 to facilitate commercial and legal transactions between Americans and the papal states. In 1848, Congress approved President James K. Polk's proposal to raise the consulate to a ministry. This action was designed to affirm the reformist Pope Pius IX, improve commercial prospects in Rome, gain influence in other Catholic states, and please the burgeoning Catholic vote at home.

Relations formally began in 1848 when Jacob L. Martin the first U.S. Chargé d’Affaires presented his credentials on August 19 in Rome. Martin died seven days later on August 26. Lewis Cass, Jr.
