The Plantagenet Dynasty was a royal family that ruled England from 1154 to 1485. It began with Henry II, who established a powerful monarchy and expanded the kingdom's territories. The dynasty is known for significant events, including the signing of the Magna Carta in 1215 and the conflicts of the Hundred Years' War. The Plantagenets produced several notable monarchs, including Richard the Lionheart and King John. The dynasty ended with the Wars of the Roses, a series of civil wars for control of the throne, leading to the rise of the Tudor Dynasty with Henry VII.
