Subutai (Mongolian: Сүбээдэй, Sübeedei; Classic Mongolian: Sübügätäi or Sübü'ätäi; Tsubodai 1175–1248) was the primary military strategist and general of Genghis Khan and Ögedei Khan. He directed more than twenty campaigns in which he conquered thirty-two nations and won sixty-five pitched battles, during which he conquered or overran more territory than any other commander in history. He gained victory by means of imaginative and sophisticated strategies and routinely coordinated movements of armies that were hundreds of kilometers away from each other. He is also remembered for devising the campaign that destroyed the armies of Hungary and Poland within two days of each other, by forces over five hundred kilometers apart.
Subutai is regarded in history as one of Genghis Khan's and the Mongol Empire's most prominent generals in terms of ability and tactics helping with the military campaigns in Asia and Eastern Europe. He commanded many successful attacks and invasions during his time and was rarely defeated.
