What is "subutai"

Subutai ( Classical Mongolian: Sübügätäi or Sübü'ätäi; ; Modern Mongolian: Сүбээдэй, Sübedei; 1175–1248) was an Uriankhai general, and the primary military strategist 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.
