How old did Eleanor of Aquitaine live to be?

Answer 1

Assuming by she, you mean Eleanor of Provence, her marriage to Henry III of England lasted between January 14, 1236 and the King's death on November 16, 1272. She married him when she was around twelve years old.

Answer 2

She was either 81 or 82. We have the date of her death (April 1st 1204), but only the year of her birth (1122). So her exact age would depend on whether she was born before or after April 1st.

Answer 3

Her first marriage was to Louis VII of France, in 1137, when she was only 15. It was annulled in 1152 despite the couple having two daughters.

Her second marriage was promptly to Henry, Duke of Normandy - she was 30 years old and Henry became King Henry II in 1154. They were married until his death in 1189, when her son Richard I became king.

She died at age 82 in 1204 when her youngest son John was king, and just three years before her grandson Henry became King Henry III.
