There used to be only one championship in Italy - Campionato Italiano Rally (C.I.R.). Now Tropheo Rally Asfalto (T.R.A.) was re-branded to championship so they have two. All the rest is trophies and cups (dozens). Czech republic has 6x less citizen and maybe 10x less rally events despite that we (Czechs) have 2 championships as well and in 2007 we had even 3. Basically it's same like here. The intenational championship has better driver quality but the national one has WRC, national or old cars allowed. The Italian IRC is just a cup of minor importance.

I don't count any historic events...
