I shall call Ideological State Apparatuses (ISAs) a certain number of realities which present themselves to the immediate observer in the form of distinct and specialized institutions: ...

the religious ISA (the system of the different churches) | the educational ISA (the system of the different public and private ‘schools’) | the family ISA | the legal ISA | the political ISA (the political system, including the different parties) | the trade-union ISA | the communications ISA (press, radio and television, etc.) | the cultural ISA (literature, the arts, sports, etc.).
