Mongol invasions of Japan (元寇, Genkō) in 1274 and in 1281 were major military events in Japanese history.[1]Kublai Khan twice tried to conquer the Japanese islands; and his armies failed both times.
The two failed invasion attempts are important because they were defining events in Japanese history.[2]
The attempts show the limits of Mongol (Yuan Dynasty) ability to expand the Chinese empire.[3]
