Henry II was born in 1133 in Le Mans, France to Geoffrey Plantagenet and Matilda. He was well educated as a child. In 1152, he married Eleanor of Aquitaine, greatly increasing his wealth and lands. Henry became embroiled in a civil war with his mother Matilda against King Stephen. He was crowned king of England in 1154 after the death of Stephen. As king, Henry established common law and improved the financial system. However, tensions grew with Thomas Becket and his sons, leading to rebellions against Henry before his death in 1189.
