Catherine Parr (c. July or August 1512 – 5 September 1548) was Queen of England and Ireland as the last of the six wives of King Henry VIII from their marriage on 12 July 1543 until Henry's death on 28 January 1547. Catherine was the final queen consort of the House of Tudor, and outlived Henry by a year and eight months. With four husbands, she is the most-married English queen consort. She was the first woman in England to publish in print an original work under her own name in the English language.
Catherine enjoyed a close relationship with Henry's three children, Mary, Elizabeth and Edward. She was personally involved in the education of Elizabeth and Edward. She was influential in Henry's passing of the Third Succession Act in 1543 that restored his daughters Mary and Elizabeth to the line of succession to the throne. Catherine was appointed regent from July to September 1544 while Henry was on a military campaign in France; in the event that he lost his life, she was to rule as regent until Edward came of age. However, he did not give her any function in government in his will.
