Philip II (1527-1598) was the only son of Charles V and Isabella of Portugal. In 1551, following the imperial Diet of Augsburg, he became the regent of Spain. After his father's abdication, he was crowned the king of Spain. Titian portrays the prince, aged about twenty-four dressed in a magnificent, lavishly decorated set of armour. The whiteness of his skin corresponds to his white stockings and the greenish golden sheen on his armour. In this way, the prince's pale complexion appears more distinguished.
