Even to the present day, Boston still commands the largest percentage of Irish-descended people of any city in the United States. With an expanding population, group loyalty, and block by block political organization, the Irish took political control of the city, leaving the Yankees in charge of finance, business and higher education. The Irish left their mark on the region in a number of ways: in still heavily Irish neighborhoods such as Charlestown and South Boston; in the name of the local basketball team, the Boston Celtics; in the dominant Irish-American political family, the Kennedys; in a large number of prominent local politicians, such as James Michael Curley; in the establishment of Catholic Boston College as a rival to Harvard; and in underworld figures such as James "Whitey" Bulger.
