  Mary was soon the focus for rebellion. In 1569 there was a major Catholic rising in the North; the goal was to free Mary, marry her to Thomas Howard, Duke of Norfolk, and put her on the English throne. After the rebels' defeat, over 750 of them were executed on Elizabeth's orders. In the belief that the revolt had been successful, Pope Pius V issued a bull in 1570, titled Regnans in Excelsis, which declared "Elizabeth, the pretended Queen of England and the servant of crime" to be excommunicated and a heretic, releasing all her subjects from any allegiance to her. Catholics who obeyed her orders were threatened with excommunication. The papal bull provoked legislative initiatives against Catholics by Parliament, which were, however, mitigated by Elizabeth's intervention. In 1581, to convert English subjects to Catholicism with "the intent" to withdraw them from their allegiance to Elizabeth was made a treasonable offence, carrying the death penalty. From the 1570s missionary priests from continental seminaries went to England secretly in the cause of the "reconversion of England". Some were executed for treasonable conduct, engendering a cult of martyrdom.
  
  Regnans in Excelsis gave English Catholics a strong incentive to look to Mary as the legitimate sovereign of England. Mary may not have been told of every Catholic plot to put her on the English throne, but from the Ridolfi Plot of 1571 (which caused Mary's suitor, the Duke of Norfolk, to lose his head) to the Babington Plot of 1586, Elizabeth's spymaster Francis Walsingham and the royal council keenly assembled a case against her. At first, Elizabeth resisted calls for Mary's death. By late 1586, she had been persuaded to sanction Mary's trial and execution on the evidence of letters written during the Babington Plot. Elizabeth's proclamation of the sentence announced that "the said Mary, pretending title to the same Crown, had compassed and imagined within the same realm diverse things tending to the hurt, death and destruction of our royal person." On 8 February 1587, Mary was beheaded at Fotheringhay Castle, Northamptonshire. After the execution, Elizabeth claimed that she had not intended for the signed execution warrant to be dispatched, and blamed her secretary, William Davison, for implementing it without her knowledge. The sincerity of Elizabeth's remorse and whether or not she wanted to delay the warrant have been called into question both by her contemporaries and later historians.
