The story in brief
In 1242, Mongol armies pulled back out of central Europe, and historians still debate why. This Short runs through the empire's rise and fall in under a minute.
In 1206, Temujin was proclaimed Genghis Khan. By 1221 his armies had sacked Bukhara and Samarkand. He died in 1227, but his heirs kept expanding, and in 1241 they crushed Polish and Hungarian forces. They took Baghdad in 1258, and in 1260 the Mamluks stopped them at Ain Jalut.
At its peak, the empire covered more than 23 million square kilometres, making it the largest contiguous land empire. Kublai Khan's invasions of Japan in 1274 and 1281 failed because of storms and stiff Japanese resistance, not storms alone. By then the empire had split into rival khanates, and in 1368 the Yuan dynasty was driven out of China.
