Tudor Successions
During the short-lived attempt to place Lady Jane Grey on the throne after the death of Edward VI in 1553, Throckmorton tried to keep contact with both supporters of both her and Queen Mary Tudor. Eventually he began to support the latter.
However, in January 1554 he was suspected of complicity in Wyatt's Rebellion and arrested. Later historians have suspected he was at least involved, either because of his Protestantism or due to his dismay at the growing Spanish influence in the court.
Throckmorton was brought to trial at the Guildhall on 17 April 1554. He managed to convince the jury of his innocence although the court was openly hostile to him. The judges included Sir Roger Cholmeley, who was trying to impress the Catholic Mary. As a result of the verdict, the court fined and imprisoned the jury and sent Throckmorton to the Tower. When he was released the next year, he fled to exile in France. Though there were people who wanted to put him on trial again, he was pardoned in 1557, and was employed by Queen Mary.
