My bible study's a little rusty but isn't that supposedly why they crucified him, for calling himself King of the Jews?
People should avoid using the new testament of the bible without outside supporting evidence when looking for the historical basis of the events. Everything that was included in there was agreed upon by leading Bishops and Emperor Constantine purely for political expedience. They wished to ensure that the christian religion was as homogeneous as possible so that the Roman Empire would not fracture apart into factions of religious infighting. That's the reason there is such a thing as the Roman Catholic Church in the first place.
