She was noted for holding Washington social functions in which she invited members of both political parties, essentially spearheading the concept of bipartisan cooperation. Previously, founders such as Thomas Jefferson would only meet with members of one party at a time, and politics could often be a violent affair resulting in physical altercations and even duels. Madison helped to create the idea that members of each party could amicably socialize, network, and negotiate with each other without violence. By innovating political institutions as the wife of James Madison, Dolley Madison did much to define the role of the President's spouse, known only much later by the title first lady—a function she had sometimes performed earlier for the widowed Thomas Jefferson.
