What was the french flag during the 1600?

During the 1600s, the French flag was primarily a solid blue banner, often associated with the royal standard of King Louis XIII and his successors. The flag evolved over time, with the introduction of the white fleur-de-lis symbol representing the monarchy. By the end of the century, the flag began to take on its more recognizable tricolor form, which would be officially adopted during the French Revolution in the late 18th century.
