After a broken ankle stopped him from being a soldier he became a diplomat. He then spent eleven years in the court of Urbino.

Castiglione liked many things such as singing, dancing, playing games, and listening to music. He became friends with Duke Guidobaldo whom he had served as a soldier. The two spent most of their time with the duke's wife and other members of the court The three became close friends and spent most of their time together.
During his stay at the court of Urbino he wrote a book called The Book Of The Courtier. This book changed the Renaissance greatly in many ways such as the behaviour expectations of the courtier and what his wife should do to help her husband. He also said that the courtier should be of noble birth. He should be good at certain sports like tennis, throwing rocks, jumping, running, and swimming. He should also have a broad education in many different areas and also be witty, pleasant and an aristocrat. Castiglione also wrote a drama called Tirsi in 1506.
