Sultan of the Ottoman Empire (1842-1918). Document with calligraphy of the sultan's tughra. N. p. o. d. Large folio (560 x 800 mm). 1 p.
Probably the Sultan's exequatur for the Italian consul in Galati (now Romania), Stefano Castelli. Since 1856 the port of Galati on the Danube River gained importance as the seat of the European Commission of the Danube that was established in the Paris Treaty after the Crimean War. Representatives of the seven signatory states (Austria, France, Great Britain, Prussia, Russia, Sardinia, and the Ottoman Empire) were entrusted with regulating navigation along the maritime Danube. From 1859 to 1878 the United Principalities of Moldavia and Wallachia, today's Romania and Moldovia, although de facto independent were formally a vessel of the Ottoman Empire.
