The NFC East is a division of the National Football League (NFL)’s National Football Conference (NFC). It currently has four members: the Philadelphia Eagles, the New York Giants, the Dallas Cowboys, and the Washington Redskins.

The division was formed in 1967 as the National Football League Capitol Division, keeping with the theme of having all of the league’s divisions starting with the letter “C.” The division was so named because it was centered on the capital of the United States, Washington, D.C. In 1967 and 1969 the teams in the NFL Capitol Division were Dallas, Philadelphia, Washington and the expansion New Orleans Saints, which had been replaced by the New York Giants for the 1968 season.
