not a "one-way process of political management" but, rather, that the activities of civil organizations conditioned the activities of political parties and state institutions, and were conditioned by them in turn. Louis Althusser argued that civil organizations such as church, schools, and the family are part of an "ideological state apparatus" which complements the "repressive state apparatus" (such as police and military) in reproducing social relations. Jürgen Habermas spoke of a public sphere that was distinct from both the economic and political sphere. Given the role that many social groups have in the development of public policy and the extensive connections between state bureaucracies and other institutions, it has become increasingly difficult to identify the boundaries of the state. Privatization, nationalization, and the creation of new regulatory bodies also change the boundaries of the state in relation to society. Often the nature of quasi-autonomous organizations is unclear, generating debate among political scientists on whether they are part of the state or civil society. Some political scientists thus prefer to speak of policy networks and decentralized governance in modern societies rather than of state bureaucracies and direct state control over policy.

Agriculture and a settled population have been attributed as necessary conditions to form states. Certain types of agriculture are more conducive to state formation, such as grain (wheat, barley, millet), because they are suited to concentrated production, taxation, and storage. Agriculture and writing are almost everywhere associated with this process: agriculture because it allowed for the emergence of a social class of people who did not have to spend most of their time providing for their own subsistence, and writing (or an equivalent of writing, like Inca quipus) because it made possible the centralization of vital information. Bureaucratization made expansion over large territories possible. The first known states were created in the Egypt, Mesopotamia, India, China, Mesoamerica, and the Andes. It is only in relatively modern times that states have almost completely displaced alternative "stateless" forms of political organization of societies all over the planet. Roving bands of hunter-gatherers and even fairly sizable and complex tribal societies based on herding or agriculture have existed without any full-time specialized state organization, and these "stateless"
