Anne Boleyn, the Sister of Henry's Mistress

A mistress is a woman with whom a married man has a relationship, but who is not his wife. Henry was unhappy in his marriage and he soon fell in love with another woman, Anne Boleyn, who was the sister of his mistress. The Catholic Church, which didn't allow divorces, would not let this happen. He wanted to end his marriage to Catherine to be with Anne.
