Top 10 Fiercest Warriors in History
1. Mongol Warriors: The Unstoppable Horse Archers (1206–1687 AD)

The heart of the army was the horse archers who employed hit-and-run tactics with ruthless efficiency. For a medieval knight bound by the code of chivalry, this was an act of cowardice. However, it was an efficient method to mow down enemies weighed down by armor.
The Mongol horse archers used a short composite bow made of animal horn, wood, and sinew for the bow drawstring. Their small size was ideal for use on horseback. It was also more powerful than the English longbow (despite its small size). Mongol horsemen were trained to shoot even while retreating. Their exceptional skill was what helped them expand their empire in every direction.
It is a common misconception that the Mongol 'hordes' outnumbered their foes. As it turns out, the Mongols were outnumbered in most of their famous victories. Enveloping maneuvers on the battlefield created the false impression of a larger army. They also placed dummies mounted atop horses to form a notion of innumerable soldiers.

They were also known for their war dance (called the 'Haka'), which was done to intimidate enemies. The most common weapon for Maori warriors was the club, which was used to crack open skulls.
The Maori warriors also practiced cannibalism in order to humiliate their enemies. It was also a common practice for the Maori to keep the heads of their fallen enemies as trophies. The brain and eyes would be removed and steamed in an oven. One missionary is said to have watched a chieftain say the following words to the head of an enemy chieftain:
You wanted to run away, didn’t you? But my greenstone club overtook you! And after you were cooked you were made food for me!
And where is your father? He is cooked.
And where is your brother? He is eaten.
And where is your wife? There she sits; a wife for me.
And where are your children? There they are, loads on their backs carrying food as my slaves.
