Short answers, pulled from the story.
Anne Boleyn was convicted of adultery, incest with her brother George Boleyn, and high treason, specifically plotting the death of King Henry VIII, on the 15th of May 1536. She was beheaded on the 19th of May 1536. Most historians dispute the charges; biographer Eric Ives argues the fall was primarily engineered by Thomas Cromwell, while others hold that Henry VIII himself issued the crucial instructions.
Anne Boleyn and Henry VIII married secretly on the 14th of November 1532, and a second private ceremony took place in London on the 25th of January 1533. Archbishop Thomas Cranmer formally declared the marriage valid on the 28th of May 1533, five days after he had declared Henry's marriage to Catherine of Aragon null and void.
Anne Boleyn provided the occasion for Henry VIII to break with the Catholic Church and declare the independence of the Church of England from the Vatican. She actively promoted evangelicals, protected scholars working on English translations of the scriptures, and is credited with influencing reformist bishops appointed during her time as queen. John Foxe argued in his Actes and Monuments that Anne had helped save England from Roman Catholicism.
Anne Boleyn's daughter was Elizabeth, born slightly prematurely on the 7th of September 1533, who became Queen Elizabeth I of England in 1558. Anne entrusted Elizabeth to the care of Matthew Parker before her death; Parker later became Archbishop of Canterbury and one of the chief architects of Anglican thought during Elizabeth's reign.
Anne Boleyn was buried in an unmarked grave in the Chapel of St Peter ad Vincula at the Tower of London. Her skeleton was identified during renovations of the chapel in 1876, in the reign of Queen Victoria, and reinterred there in 1877. Her grave is now clearly marked on the marble floor of the chapel.
Contemporary accounts describe Anne Boleyn as being of middling stature with a dark complexion, long neck, wide mouth, and black eyes described as beautiful. The Venetian diarist Marino Sanuto the Younger, who saw her at Calais in October 1532, wrote that she was "not one of the handsomest women in the world." All her portraits were destroyed by Henry VIII's order, and many surviving images may be copies of a lost original that existed as late as 1773.
