The Treaty of Hünkâr İskelesi (once commonly spelled Unkiar Skelessi, and translating to The Treaty of "the Royal Pier" or "the Sultan's Pier") was a treaty signed between the Russian Empire and the Ottoman Empire on July 8, 1833, following the military aid of Russia against Mehmed Ali that same year.

 Although Persia had won a clear victory in the last Ottoman–Persian War (1821–23) over their Ottoman arch rivals, it had been considerably weakened by years of ineffective rulers, the defeat against Russia in 1813 and 1828 in which they lost all of the Caucasus, and with the increasing occupation by Great Britain of Egypt, during the years of 1873 to 1881, and on top of that the decaying Ottoman Empire, Imperial Russia stepped up its campaign to wrest full control over Central Asia.

The U.S.—German Peace Treaty is a peace treaty between the U.S. and German governments, signed in Berlin on August 25, 1921, in the aftermath of World War I.

 Ratifications were exchanged in Berlin on November 11, 1921, and the treaty became effective on the same day.

 The treaty was registered by the Secretariat of the League of Nations on 21 October 1919.
