Dyuden or Tudan (Russian: Тудан) was a brother of Toqta, the khan of the Golden Horde and a great grandson of Batu Khan.
He was appointed as a general by Toqta and his campaign devastated 14 towns in the territory of modern Russia in 1293,[1] including Moscow,[2] while the grand prince, Dmitry, was forced to flee to Pskov, allowing Andrey to take the title of grand prince.
[3] Dyudan had a son, Shchelkan, who was Özbeg Khan's ambassador in the Principality of Tver in 1327.
