To please the French King, Henry II had his son and Margaret crowned together in Winchester Cathedral on 27 August 1172.

Henry may have started the process to have their marriage annulled ostensibly due to her adultery, but in reality, because she could not have children.

[citation needed] Margaret was sent back to France, according to E. Hallam (The Plantagenets) and Amy Kelly (Eleonore of Aquitaine and the Four Kings), to ensure her safety during the civil war with Young Henry's brother Richard the Lionheart.

After receiving a substantial pension in exchange for surrendering her dowry of Gisors and the Vexin, Margaret became the second wife of Béla III of Hungary in 1186.

[3] She was widowed for a second time in 1196 and died on pilgrimage to the Holy Land at St John of Acre in 1197, having only arrived eight days prior to her death.
