ABSTRACT
Secondary sources and illustrative anecdotes put the evolution of diverse security sectors into context. Police and military organisations have co-evolved with states, and with the expansion of states into international markets, sometimes coercing and sometimes serving communities. In this process, the instruments of state have variously dominated, co-opted, or accommodated different cultural traditions and identity groups, which also evolve in the process. Inclusion and accommodation can involve co-option of elites, ethnic units, units of convenience, recognition of individual identity, and less visible physical accommodations. Informal structures like ethnic trust networks influence whether accommodation threatens the integrity of security organisations or the security of the state.
