The term "Pagan Empire" often refers to various ancient civilizations that practiced polytheism and worshipped multiple deities. These empires, such as the Roman Empire and the Mayan Empire, were characterized by rich mythologies, rituals, and cultural practices that revolved around their gods and nature. Paganism was prevalent before the rise of major monotheistic religions like Christianity and Islam. As these religions spread, many pagan practices were either absorbed or suppressed, leading to significant cultural shifts in the regions where these empires existed.
