Anne Boleyn's trial.

April-May 1536, Henry VIII had (m2) Anne Bolelyn investigated for high treason: tried and found guilty, she was beheaded on May19th.; historians view the charges against her, which included adultery and incest, as unconvincing. Following the coronation of her daughter, Elizabeth I as queen,(m2) Anne Boleyn was venerated as a martyr and heroine of the English Reformation, particularly through the works of John Foxe. Over the centuries, she has inspired or been mentioned in numerous artistic and cultural works. As a result, she has retained her hold on the popular imagination. Anne has been called "the most influential and important queen consort England has ever had," since she provided the occasion for Henry VIII to divorce (m1) Catherine of Aragon, and declare his independence from Rome.
