Most of our modern holidays, like Christmas and Easter, are a combination of Pagan and Christian traditions. Thanksgiving, on the other hand, doesn’t have as much of a Christian influence. While Thanksgiving is not tied to any one specific religion, it’s traditions are quite similar to a number of ancient Pagan harvest celebrations. For example, in ancient Rome they celebrated the holiday of Cerelia, which honored the harvest goddess of grain called Ceres. There are around a 100 different harvest Gods and Goddesses from Greek & Roman culture so it’s clear that celebrating the harvest season was a key feature of their spiritual beliefs.
