An archdiocese is a type of diocese, which is an administrative division within the Roman Catholic Church. The term comes from the Greek words “arkhi” (ruler) and “ekklēsia” (church). An archdiocese is headed by an Archbishop who has jurisdiction over all the parishes in his territory. It typically covers a large urban area or several adjacent rural areas, and may contain multiple dioceses within it. The Archdiocese of New York City, for example, includes not only Manhattan but also other boroughs such as Brooklyn, Queens, Staten Island, and the Bronx.
