Parliaments began in Europe as institutions for aristocrats?

Parliaments began in Europe as institutions for common people, not for aristocrats. The first parliaments were established in the 12th and 13th centuries in England, France, and Spain, and they were composed of representatives from the lower social classes, such as merchants, artisans, and peasants. Aristocrats were not typically included in these early parliaments because they were seen as a threat to the power of the king.
