The National Association of Manufacturers (NAM) played an important role in the emerging conservative movement in the United States, both before and after World War II, but its contribution to the increasing militarism of that movement has received little scrutiny. Between 1958 and 1975, a combination of organizational changes peculiar to NAM and political pressures from both the right and the left led NAM to adopt and maintain a militaristic posture. In the late 1950s, a decline in the organization's membership resulted in a take over by larger corporations, which purged the board of its ultraconservative leadership. The reorganized board established a National Defense Committee (NDC) in order to promote defense industry membership and, by 1962, had selected a new permanent president, Werner Gullander. Under Gullander, the NDC moved NAM in the direction of support for defense expansion during the early 1960s.
