in mainland Japan. The Ryu-Kyu court in Naha complained in early 1847 about the presence of the French missionaries, who had to be removed in 1848. France would have no further contacts with Okinawa for the next 7 years, until news came that Commodore Perry had obtained an agreement with the islands on July 11, 1854, following his treaty with Japan. France sent an embassy under Rear-Admiral Cécille onboard La Virginie in order to obtain similar advantages. A convention was signed on November 24, 1855. As contacts between France and Japan developed during the Bakumatsu period (on the military side this is the period of the first French military mission to Japan), Japan was formed into a unique Vicariate Apostolic from 1866 until 1876.
