There's a very good reason why you can find spears in the history of every civilization and tribe on Earth. It's not just because they're simple, be it a common pointy stick or an elaborately engineered and weighted one. And it's not only because they were relatively cheap, compared to other weapons that could be mass-produced at the time.
No, spears were everywhere because spears work.
The men and women who practice HEMA, or Historical European Martial Arts, are extremely adept at swordplay, but Nikolas Lloyd (known online as Lindybeige) wanted to see if they could hold their own with history's most ubiquitous weapon. He equipped sword experts with spears and some with swords, and pitted them against each other to determine which is better, once and for all.
None of the people fighting in the video above are experts with spears and shields, but all are familiar with swordplay. They would be fighting against their favorite weapons.
For the swordsman to have a chance at the spearman, he must be extremely fast, but even speed may not be enough. As Lloyd points out, the head of the spear can move very, very fast itself. There is very little chance of a swordsman closing against an eight-foot spear from any kind of distance – and keep in mind; this is not an expert spearman. In the hands of an expert, there is even less likelihood that the sword will hit its target.
When up close, the spear's length becomes a drawback, so using a shield to get closer might be the obvious solution. Shields did raise the effectiveness of the sword against the spear, but not by much. When adding to the length of swords, the spear still came out on top. Check out the video to see the which weapon ends up being the most effective in medieval combat.
