a pretender to the English throne. By claiming to be Richard of Shrewsbury, Duke of York, Warbeck was a significant threat to the newly established Tudor dynasty, and gained support outside England. Henry VII declared Warbeck an impostor, and after his capture, Warbeck wrote a confession in which he said he was a Fleming born in Tournai around 1474. Due to uncertainty as to whether Richard of Shrewsbury had died in the Tower of London or had survived, Warbeck's claim gathered some followers, either due to real belief in his identity or because of desire to overthrow Henry and reclaim the throne. Dealing with Warbeck cost Henry VII over £13,000, putting a strain on Henry's weak state finances.
