The Tudor monarchs were a royal family that ruled England from 1485 to 1603. This period began with Henry VII, who established the dynasty after winning the Battle of Bosworth Field. The Tudors are known for significant events, including the English Reformation and the establishment of the Church of England under Henry VIII. The most famous Tudor monarch is Elizabeth I, who reigned from 1558 to 1603. Her rule is often referred to as the Elizabethan Era, marked by flourishing arts, exploration, and the defeat of the Spanish Armada in 1588. The Tudor dynasty ended with Elizabeth's death, as she left no heirs.
