Mary Tudor was the only child of Henry VIII and Catherine of Aragon to survive infancy. Her mother suffered many miscarriages before Mary's birth and her four previous pregnancies led to a still-born daughter and three short lived or still-born sons. Mary was very precious to both her parents and the royal court during her childhood. Henry VIII doted on his daughter and was heard boasting that "This girl never cries." The majority of her education came from her devout Catholic mother, and by the age of nine Mary could read and write in Latin. She studied French, Spanish, music, and dance, and by the time she was four, Mary was particularly skilled in the virginals (a type of harpsichord). Throughout her childhood, her father negotiated future marriages for her. When Mary was only two years old, she was promised to the infant son of King Francis I of France, an agreement that was broken off after three years. At the age of six, she was contracted to marry her 22-year-old first cousin, the Holy Roman Emperor, Charles V. Despite his affection for Mary, her father was disappointed that he had still produced no male heirs, or rather, that his wife had produced no male heirs, for in his mind it must be his wife that was the problem. When it became apparent that her parent's marriage was over when Mary was nine, she was sent to the border of Wales, and was called Princess of Wales, although she was never technically bestowed with the title. After Henry's divorce was finalized, Catherine of Aragon was given the title of the Princess Dowager of Wales, a name which she refused to acknowledge to the day she died. She was moved around England and separated from her daughter, who had at this point been declared illegitimate. Because of Catherine's refusal to accept the annulment of her marriage, Mary was not allowed to see her mother. In 1533, Henry VIII had a daughter by his second wife Anne Boleyn. This child, Elizabeth, replaced Mary in the line of succession. Mary was known to hate her new stepmother and continued to support her mother and the Catholic religion.
