In 1529, Charles V, Holy Roman Emperor at the Diet of Speyer revised this policy again and declared that until there was clarification of the Catholic Church's position from another Ecumenical council all further new religious developments in the empire would remain forbidden:
<blockquote>''"Those that until now have followed the Edict of Worms should continue to do so [ i.e., where Lutheranism has been forbidden, it remains forbidden]. In the areas where this has been deviated from, there shall be no further new developments and no-one shall be refused Mass [i.e., where Lutheranism has been permitted, Catholicism must be at least permitted]. Finally, the sects which contradict the sacrament of the true body and blood, shall absolutely not be tolerated, no more than the [[Anabaptists ]] [i.e., anything beyond Lutheranism or Catholicism is outlawed everywhere]."</blockquote>
The term '''Protestant''' was initially applied to a group of princes and imperial cities within the Holy Roman Empire who "protested" against this decision, and therefore originally referred only to those who wished to forbid Catholicism and enforce Lutheranism within their territories.

Only general '''families''' are listed here (due to the above-stated mulititude of List of Christian denominations); some of these groups do not consider themselves as part of the Protestant movement, but are generally viewed as such by scholars and the public at large:
