What feature of his personal life prevented Carroll from being able to legally participate in politics in the colonies?

Charles Carroll of Carrollton was a Roman Catholic, and during the colonial period, many colonies, particularly Maryland, had laws that restricted the political rights of Catholics. These laws often prevented them from holding public office or participating fully in the political process. As a result, his religion significantly limited his legal political participation in the colonies. Despite these restrictions, Carroll became an active supporter of the American Revolution and ultimately played a prominent role in the founding of the United States.
