Druids are a major division of Native religion and are located in the British Isles and Scotland. Druids are most commonly associated with the indigenous Celtic people of Ireland. Druids are known to have existed as early as the 3rd century BCE (History of Britain: Rise and Fall of the Druids). The Druids passed down their rituals and history through stories rather than written texts, so much is still unknown about their way of life. Many people in today's culture still actively practice Druidry. Today, Druidry is divided into two sects, cultural Druidism and religious Druidry. Cultural Druids are classified according to their descendants who are Druids. Usually, these people follow the practices of Druidry lightly, but most practice a second, broader religion such as Christianity. Religious Druids are classified as actively practicing the Druid religion. Most religious Druids also have ancestors who were Druids (BA Robinson). Druids were known to be very intelligent and were often an elite group. These were often priests of the Celtic religion. The Druids have no official sacred text, although there are books on astronomy believed to have been written and used by the Druids. Druids believed that mistletoe and oak trees were very sacred. Pliny, a Roman author, said that "The Druids (that's what they call their wise men) have nothing more reverence than mistletoe and the tree on which it grows, so that it is an oak . » (Pliny, sect. 95). A unique feature of the Druid religion was that it made no distinction between male and female rulers. In chapter 30 of the Annals, a book of Roman history, Tacitus describes the first Roman encounters with the Druids. He describes women as “running down the middle of paper….., John.
