The origin of birthdays has not yet been determined by scientists or researchers, according to the Huffington Post, but the development of birthdays follows these events: Egyptians were the first to throw parties, Greeks started using candles on top of cakes at celebrations, ancient Romans started to celebrate birthdays for men and the industrial revolution brought cakes to all people. Without these events, the modern birthday would not be what it is today.
The Egyptians began celebrations by throwing the world's first parties. These parties were held to celebrate the new pharaohs who, once crowned, were thought to be gods. A celebration was needed for the divine transformation, and the partying began.
The Greeks were the first to use candles on top of the cake. The reason for the candles was that the cakes were offered to Artemis, the lunar goddess. The candles were supposed to be a reminder of Artemis' beauty and a symbol of the illumination of the moon.
Ancient Romans are thought to have been the first peoples to celebrate the birthdays of common people, rather than just celebrating the birthdays of religious or famous figures. However, women's birthdays were not yet celebrated.
The industrial revolution made it possible for all people to have access to delicious cakes instead of just the wealthy. This would have made it possible for people to celebrate birthdays with the traditional birthday cake now that cakes were affordable.
