The Catholic University of America is a private Roman Catholic research university in Washington, D.C. It is a pontifical university of the Catholic Church in the United States and the only institution of higher education founded by U.S. Catholic bishops. Established in 1887 as a graduate and research center following approval by Pope Leo XIII, the university began offering undergraduate education in 1904. It is classified among "R2: Doctoral Universities – High research activity". Its campus is adjacent to the Brookland neighborhood, known as "Little Rome", which contains 60 Catholic institutions, including Trinity Washington University, the Dominican House of Studies, and Archbishop Carroll High School, as well as the Basilica of the National Shrine of the Immaculate Conception. CUA's programs emphasize the liberal arts, professional education, and personal development. The school stays closely connected with the Catholic Church and Catholic organizations. The residential U.S. cardinals put on the American Cardinals Dinner each year to raise scholarship funds. The university also has a long history of working with the Knights of Columbus; its law school and basilica have dedications to the involvement and support of the Knights.
