There are 43 African American Members serving in the 112th Congress, all in the House of Representatives. There have been 133 African American Members of Congress: 127 have been elected to the House; 5 have been elected to the Senate; and 1 has been appointed to the Senate. There have been 104 Democrats, 101 in the House and 3 in the Senate; and 29 Republicans, 26 in the House and 3 in the Senate. The number of African American Members has steadily increased since the first African Americans entered Congress in 1870. There were fewer than 10 Members until the 91st Congress (1969-1971). In the 98th Congress (1983-1985), the number surpassed 20 for the first time and then jumped to 40 in the 103rd Congress (1993-1995). Since the 106th Congress (1999-2001), the number has remained between 39 and 44 serving at any one time. The first African American Member of Congress was Hiram Rhodes Revels (R-MS), who served in the Senate in the 41st Congress (served 1870-1871). The first African American Member of the House was Joseph H. Rainey (R-SC), who also served in the 41st Congress. Shirley Chisholm (D-NY), elected to the 91st through 97th Congresses (1969-1983), was the first African American woman in Congress. Since that time, 30 other African American women have been elected, including Senator Carol Moseley-Braun (D-IL, 1993-1999), who is the only African American woman, as well as the first African American Democrat, elected to the Senate. Representative John Conyers, Jr. (D-MI, 1965-present), the current chair of the House Judiciary Committee, holds the record for length of service by an African American Member (46 years). He was first elected to the 89th Congress (1965-1967) and has served since January 3, 1965. Representative James E. Clyburn (D-SC, 1993-present) and former Representatives William H. Gray III (D-PA, 1979-1991) and J.C. Watts (R-OK, 1995-2003) have been elected to the highest leadership positions held by African American Members of Congress. Representative Clyburn, the House Assistant Democratic leader in the 112th Congress, served as the House majority whip in the 110th and 111th Congresses and as vice chair of the House Democratic Caucus in the 108th and 109th Congresses. Representative Gray was chair of the House Democratic Caucus in 1989 (101st Congress). Later in that Congress, when a vacancy occurred, he was elected House majority whip, a position he held until his resignation from Congress in September 1991 (102nd Congress). Representative Watts served as chair of the House Republican Conference in the 106th-107th Congresses (1997-2001). Twenty African Americans have served as committee chairs, 19 in the House and 1 in the Senate. The Congressional Black Caucus (CBC), whose origins date back to 1969, currently has 43 members. Over its 40-year history, the CBC has been one of the most influential caucuses in Congress.
