'Mamai' or 'Mamay' was a powerful military commander of the
Blue Horde in the
1370s, who resided in the western part of this nomadic state, which is now the Southern
Ukrainian Steppes and the
Crimean Peninsula. He split apart from Khans of the Golden Horde, trying to establish his own state.
Mamai, holding military rank of ''tumenbashy'' (''tyomnik'', ''тёмник'' in
Russian — commander of 10,000 troops, loosely equivalent to a modern
general) was a descendant
Genghis Khan through
Nogai but ineligible for the
Saray throne because he was not of
Batu's line. In
1378–
1380 he tried to force
Russians to pay annual tribute to him instead of the Golden Horde.
After being badly defeated by Russians under
Dmitri Donskoi at the
Battle of Kulikovo (
1380), Mamai was assassinated in
Caffa (
Crimea) by the
Genoese, who could not forgive the total waste of a military unit of Genoese
crossbowmen who were slaughtered by the Russians. The memory of Mamai has endured for centuries. Contemporary
Russian has an expression ''like Mamai passed'' (как Мамай прошел) to describe an utter mess.
Purported descendants
One of his sons, Manzur Kiyat, purportedly escaped to
Lithuania, and, serving Grand Prince
Vytautas the Great, received the title of Prince of
Hlinsk with multiple estates around the modern city of
Poltava (
Ukraine). These legendary events could have taken place in the
1400s, although the first documented mention of the
Hlinski princes is made in
1437.
Mikhail Hlinski was the most illustrious member of the family: he studied at the German university, took part as a knight in the
Italian Wars, was the most powerful man in Lithuania in the
1500s, but later rebelled and run away with his brothers to
Muscovy and helped the Russians to retake the city of
Smolensk. His niece
Elena Glinskaya was married to
Vasily III, Grand Prince of
Moscow, and
Ivan the Terrible was her son.
