«“Conservative” is no longer a preferred term in Iranian political discourse. Usulgara', which can be clumsily translated as “principlist” is the term now used to refer to an array of forces that previously identified themselves as conservative, fundamentalist, neo-fundamentalist, or traditionalist. It developed to counter the term eslahgara, or reformist, and is applied to a camp of not necessarily congrous groups and individuals.»
