Were the musketeers the supporters of the king or parliament?

The Musketeers, particularly in the context of Alexandre Dumas' novel "The Three Musketeers," were primarily supporters of King Louis XIII of France. They served as part of the king's royal guard and were loyal to the monarchy, often engaging in adventures that involved defending the king's interests. While they occasionally intersected with political intrigues involving the nobility and the queen, their allegiance remained with the crown rather than the parliament.
