Since the Shī'ī response to constitutionalist notionsof government is potentially a very large subject,for the purposes of this discussion Shī'ī will betaken to mean the members of the orthodox'ulamā, those most committed tothe sharī'a and learned in itsprecepts. Whilst even within this group there is awide diversity of opinion, it is hoped that, bylooking at works written over a longer period, thediscussion will show that the response by aparticular ‘ālim toconstitutionalism is to some extent influenced bythe political conditions prevailing at the time ofwriting. These form a factor together with therestrictions imposed by the sharī'ain shaping the views of particular writers. Theideology under consideration is constitutionalism,but it will be observed that for a large part thesubject matter treated consists of ideas such asrepresentation, consultation, legislation, freedomand equality, which are allied to theconstitutionalist theory of government, rather thanthe complete theory itself.
