The word "pagan" (without a capital P) is often used to describe anyone who holds religious beliefs that differ from the main world religions. A similar term is "heathen". Today Pagan, with a capital P, often refers to people who follow Neo-Pagan religions that honour the Earth. The best known Neo-Pagan religion is Wicca. Another well-known neo-pagan faith is Druidism, but there are many other Neo-Pagan religions with different beliefs.
