Placing the clubs in the context of twentieth-century middle-class culture, Charles maintains that they represented the response of locally oriented, traditional middle-class men to societal changes. The groups emerged at a time when service was becoming both a middle-class and a business ideal. As voluntary associations, they represented a shift in organizing rationale, from fraternalism to service. The clubs and their ideology of service were welcome as a unifying force at a time when small cities and towns were beset by economic and population pressures.
