I want to know the answer to the following question:
Until when did Henry III continue his attempts to reclaim Normandy?
All the background I'm provided with is that "Henry III continued his attempts to reclaim Normandy and Anjou until 1259, but John's continental losses and the consequent growth of Capetian power in the 13th century proved to mark a "turning point in European history".". Is that enough to answer the question?
Answer: yes
