"And yet, like her father and grandfather, Mary possessed many traits which should have fit her for a successful reign. Like all Tudors, she was intelligent, courageous, dignified, ad resilient. These qualities had ensured her survival during her father's and brother's reigns. She was well educated: in addition to her native tongue, she spoke Spanish, French, and Latin and could read Greek and Latin. Nor was she entirely serious: she danced and played the lute. Finally, Mary was not without mercy. Apart from Northumberland, few died for the plot to usurp the throne. Even Lady Jane Gray and Guildford Dudley were allowed to live, for the time being, albeit as close prisoners in the Tower. Unfortunately, she was at her accession naive in politics and inexperienced in government, having been repudiated by her father and, thus, never groomed to succeed. Without training or experience, she was forced to rely on her conscience and her faith. In the end, she had too much of the one and was too inflexible in the other for her own or the country's good. More specifically, she was half-Spanish and all Catholic and so saw it as her God-given duty to ally her country with the Spanish Empire and undo the "heresies" of the previous 20 years by restoring the Roman Catholic Church in England at any cost. Both policies would bring misery to her people."
