Anna was the eldest daughter of Maximilian II, Holy Roman Emperor, and Maria of Spain, who were first cousins. She was born in Spain during the reign of her maternal grandfather, Emperor Charles V, but lived in Vienna from the age of four. Anna was considered her father's favorite child. The story goes that he enjoyed playing and gambling with her and once a meeting of the Estates of Hungary was postponed because Anna was sick. She received a Catholic education even though her father was sympathetic to Lutheranism.
