Why is a boxing ring called a ring and not a square as ring is round and actually the ring is square?

Because boxers used to fight in a circle drawn on the floor, called the ring. This name stuck On even after the boxing ring became a square in the old days the fighters were surrounded by the crowd in a circle. They call the fighters to the ring. Because a long long time ago, before "rings" when two men brawled in the dirt people use to watch by standing round them, in a ring shape, then when a stage was added the name just stayed the same, the squared circle.
