History of justice is not only the history of state justice. Rather, we often deal with a coexistence of state, parastatal and non-state courts. Interesting research questions emerge out of this constellation: Where are notions of just conflict resolution most likely to be enforceable? To what extent is non-state jurisdiction a mode of self-regulation of social groups who define themselves by means of ethnic, religious or functional criteria? How do state and non-state ambitions interact? This collective volume contains contributions exploring non-state and parastatal justice between the 17th century and the present in Europe, Asia, North America as well as from a global perspective.
