What about commissariat?  {pmcgraw at LINFIELD.EDU,Net}

I immediately thought of prole-tariat.
There's also secretariat                      {prez234 at JUNO.COM,Net}

My point was founded on the general acceptance of the above terms being
loans from French.  Also these terms can be identified as having -iat as a
suffix.  In the case of mullahtariat the the second element is -tariat.
In commentariat I wonder if the form is from commentar(y) + -iat, in which
case I cannot think of a parallel of English origin, or from commen(t) +
-tariat, as in mullahtariat.
