Anne Boleyn

Anne Boleyn was Queen of England from 1533-1536 as the second wife of King Henry VIII. She was a key figure in the English Reformation. Anne started out as the maid of honor for Catherine of Aragon, Henry VIII's first wife. Henry began to pursue Ann in 1525, and he wanted to annul his marriage to his wife Catherine so that he could marry Anne. The Vatican would not allow Henry to annul his marriage to Catherine; this began the breaking down of the power of the Catholic Church in England. Anne gave Henry documents from the early Church that said that the king had royal supremacy. This is what started the English Reformation, because Henry decided that he would split away from the Catholic Church in order to divorce Catherine and marry Anne, which is what he ended up doing.
