Did Mongols and knights ever fight?

Yes. Unlike most warrior matchups, this one really happened: in 1241 Mongol armies met European knights in central Europe, above all at the Battle of Legnica, as well as at Mohi in Hungary.

Who won when Mongols fought knights?

The Mongols, decisively. At Legnica in 1241 they destroyed a combined army of Polish and German knights, using mobility, discipline and horse archery to undo the heavy cavalry charge.

Why did the Mongols stop their advance into Europe?

Traditionally because the Great Khan Ogedei died in December 1241 and the princes turned east to the succession, but historians debate it: Batu never went to the election, and the withdrawal may also reflect limited aims, losses and poor pasture in Hungary. Europe was spared less by its knights than by the Mongols' own decisions.

Why were Mongols so effective against knights?

Their horse archers could strike from a distance and refuse close combat, their feigned retreats drew knights out of formation, and their discipline and coordination let them encircle a heavier but slower enemy.

Were the Mongols ever defeated?

Yes. Their westward expansion in the Middle East was checked by the Mamluks of Egypt at the Battle of Ain Jalut in 1260, one of the first major defeats of a Mongol army in the field.

Mongol vs Knight: when the steppe met the knights

Most warrior matchups are fantasies, but this one really happened. In 1241 the Mongols swept into central Europe¹ and met its armoured knights in battle, above all at Legnica. One side trusted in the armoured charge; the other in the bow, the horse and the feigned retreat. The result stunned Europe. Here they are, side by side.

The Mongol

The Mongol warrior was a horse archer of the steppe, raised in the saddle and able to shoot at the gallop. Mongol armies under Genghis Khan and his heirs, led by generals such as Subutai, relied on speed, discipline and the feigned retreat³ to draw an enemy out and then encircle him. At Legnica in 1241 they shattered a combined army of Polish and German knights¹. No European victory halted their great western advance: the Mongols withdrew in 1242, traditionally because of the death of the Great Khan Ogedei, though historians also point to losses, logistics and the limited aims of the campaign.

The knight

The European knight was a heavily armoured noble horseman whose decisive weapon was the couched lance and whose decisive tactic was the massed charge. Against other European armies it was devastating, from Hastings to the Crusades of Richard the Lionheart. But against the Mongols at Legnica the charge met an enemy who simply would not stand to receive it, and who answered armour with mobility and massed arrows.

So who won?

Unusually for these matchups, there is a real answer: when Mongol and knight met at Legnica in 1241, the Mongols won, and decisively. Their mobility, discipline and horse archery undid the heavy charge, and the Mongol withdrawal of 1242, traditionally linked to the death of the Great Khan Ogedei, spared central Europe from more. It is a reminder that the armoured knight, so dominant at home, was not the measure of every battlefield. The Mongols themselves were finally checked far away, by the Mamluks at Ain Jalut in 1260.
