It's wrong to make assumptions, but it's safe to assume that you, the reader of this article, owns at least one pair of pants. You probably think that the reason you wear pants is because they are comfortable and trendy, but do you know WHY they have become to trendy? As it turns out, it dates back to the Ancient Romans.
The Romans had a laughable cavalry unit, and this lead them to keep getting whooped by a man by the name of Hannibal. The problem was that the Romans were trying to ride horses while wearing their little skirts, which made for an unpleasant experience and often distracted the rider. The Romans decided to wear long pants, that covered their legs, which made the riding experience more enjoyable!
It wasn't just the Romans that were wearing pants because of horses. In fact, if you look all around the world, the initial reason for the creation of pants, was to make horseback riding more tolerable. The Japanese started wearing pants to ride horses, and the Native Americans didn't wear pants...until they were introduced to horses by the Europeans! Since men with horses were seen wearing pants, pants themselves became a sign of honor and royalty!
