A cooperative ("coop"), co-operative ("co-op"), or coöperative ("coöp") is an autonomous association of persons who voluntarily cooperate for their mutual social, economic, and cultural benefit. Cooperatives include non-profit community organizations and businesses that are owned and managed by the people who use its services (a consumer cooperative) and/or by the people who work there (a worker cooperative).

Various aspects regarding cooperative enterprise are the focus of study in the field of cooperative economics.

Cooperation dates back as far as human beings have been organizing for mutual benefit. Tribes were organized as cooperative structures, allocating jobs and resources among each other, only trading with the external communities. In alpine environments, trade could only be maintained in organized cooperatives to achieve a useful condition of artificial roads such as Viamala in 1473. Pre-industrial Europe is home to the first cooperatives from an industrial context.^{[citation needed]}

The Crisis is the official magazine of the National Association for the Advancement of Colored People (NAACP), and was founded in 1910 by W. E. B. Du Bois (editor), Oswald Garrison Villard, J. Max Barber, Charles Edward Russell, Kelly Miller, W.S. Braithwaite, M. D. Maclean.

The original title of the journal was The Crisis: A Record of The Darker Races. From 1997 to 2003, it appeared as The New Crisis: The Magazine of Opportunities and Ideas, but the title has since reverted to The Crisis. The title derives from the poem "The Present Crisis" by James Russell Lowell. Published monthly, by 1920 its circulation had reached 100,000 copies. Du Bois proclaimed his intentions in his first editorial:

Predominantly a current-affairs journal, The Crisis also included poems, reviews, and essays on culture and history. Du Bois' initial position as editor was in line with the NAACP's liberal programme of social reform and racial equality, but by the 1930s Du Bois was advocating a form of black separatism. This led to disputes between Du Bois and the NAACP resulting in his resignation as editor in 1934. He was replaced by Roy Wilkins.
