Sary-Aka's embassy

Sary-Aka's embassy (Russian: Посольство Сарайки) was a mission from the commander of the Blue Horde Mamai sent to Russian Eastern border province of Nizhny Novgorod in 1374 to undermine the influence of the Prince of Moscow in his struggle for supremacy among the Russian provinces and due to his open opposition to Mongol authority in Russia. The embassy was ambushed and the survivors were imprisoned in the wooden fort of Nizhny Novgorod until the 31st of March 1375 when Sary-Aka with the rest of Tatars were massacred by Russians.

Sary-Aka's embassy was dispatched by Mamai, a military commander of the Blue Horde, which ruled over lands in what is now the Southern Ukrainian Steppes and the Crimean Peninsula, to Nizhny Novgorod in 1374. The ambassador was accompanied by a military troop that constituted one thousand of men-at-arms. The same year the detachment was assaulted by the Russian troops to the south of Nizhny Novgorod with most of its members killed. The survivors were captured and imprisoned in Nizhny Novgorod Kremlin along with the ambassador himself, although they were allowed to stay together and keep the weapon with them. In March 1375 a congress of Russian princes took place in Pereslavl-Zalessky town in Yaroslavl Oblast. It was moderated by the Prince of Moscow and Grand Prince of Vladimir Dmitry Ivanovich Donskoy. Among the others the congress was attended by warlords of the Principality of Ryazan, Oleg Ivanovich, and of Nizhny Novgorod and Suzdal, Dmitri Konstantinovich of Suzdal. The Grand Prince of Tver Mikhail II did not attend although.
