Soon, however, young King Edward became sick and died at the age of thirteen. Elizabeth's half-sister Mary became Queen. Mary was a devout Catholic and demanded that all of England convert to the Catholic religion. Those that didn't were thrown in prison or even killed. Mary also married a Spanish prince named Philip.
The people of England didn't like Queen Mary. Queen Mary became worried that Elizabeth would try and take over her throne. She had Elizabeth put in prison for being a Protestant. Elizabeth actually spent two months in a jail cell at the Tower of London. 」
