You may have heard that the tradition of bridesmaids comes from a belief that evil spirits would try to curse the bride, so a group of women would dress all the same to confuse the spirits. But today in my bar review class, I learned that the tradition of having a maid of honor and best man comes from a slightly less silly place. In medieval times, marriage was simply a property arrangement between two families. Only one witness is legally required to validate the marriage, but in order to ensure that the property transaction went according to plan and one family didn't get screwed over, each family sent a representative to the wedding to witness the transaction. These representatives became known as the maid of honor and the best man. Hopefully this shows up on the exam!
