The North Campus residence community was built in 1950 to accommodate the surge in undergraduate student enrollment in the post-World War II years. Because of the large number of spirited World War II veterans it housed, students living there and their counterparts across campus called it "The Jungle." Eight of the halls in North Campus are named for the counties of Connecticut, and the other three are named for men who served as Connecticut governors in the 1940s. The Northwest Quadrangle was also built in 1950, and these units are named for 19th-century Connecticut businessmen. In their early years, the residences were also known as "the Frats," as they housed the members of nearly two dozen campus fraternities.
