There are many theories as to how this holiday developed.
This article traces the possibility that Purim celebration is rooted in one or more ancient cultures. There is a major difference between the ancient holidays and Purim. The Purim celebration goes beyond the merriment of these ancient festivals, transforming the celebration to rejoicing in redemption and God's covenant. Excerpted with permission from Every Person's Guide to Purim (Jason Aronson, Inc.).
According to many modern Bible scholars, the festival of Purim did not have its source in the story told in the Book of Esther. According to Hayyim Schauss, Purim originally appeared among the Persian Jews and was adopted by them from their non-Jewish neighbors. The Jews of Persia observed, along with their neighbors, an annual festival that was celebrated in the middle of the last of the winter months. From the beginning, it had the characteristics of a spring masquerade and was a festival of merriment, play, and pranks. A very popular festival with both Persian and the Babylonian Jewry, it eventually spread to Palestine.
Theodore Gaster presents several theories for the origin of Purim in his volume Festivals of the Jewish Year. In one theory, Purim is asserted to date back to the Babylonian New Year Festival. On this day, the gods were believed to determine the fate of men by lot, and the Babylonian word for lot was puru. It was also postulated that the festival was characterized by a ritual pantomime that portrayed the conquest of Babylonian gods over those of its neighbors. The problem with this theory is that the Babylonian New Year Festival fell in Nisan (April), not in Adar (March), and it lasted a full 10 or 11 days.
Another theory starts from the fact that both the ancient Greek version of the Bible (the Septuagint) and the historian Josephus call the festival not Purim but "Furdaia," which is contended to be a distortion of the Old Persian "Farwadigan," a feast held toward the end of the month of March. The fact is, however, that the Feast of Farwadigan lasted at least five days and was primarily a commemoration of the dead.

A third theory connects the name Purim with the Hebrew word purah--"wine press"--and assumes that the festival arose in the Greek period as an adaptation of the Greek festival of Pithoigia, or "Opening the Wine Casks." Again, this theory has its problems. The opening of wine casks occurs in the fall rather than in the spring, and the plural of the word purah is purot, not purim.
