A. Established new church denominations

established new church denominations.

Explanation:

The Reformation lead by Protestants turned into the formation of new doctrines that eventually organized in new denominations.

The Calvinists, Presbyterian, Anabaptist, and Reformed movements formed a wide array of denominations among north Europe.

Perhaps the ideas behind Lutheranism were so strong, that other thinkers emerged to support or adapt them with some minor differences.

These thinkers are Ulrich Zwingli,  John Calvin, and John Knox , that taking Martin Luther ideals they promoted "Five Solas", the points of doctrine that deviated from the Catholic Church. Most of them were sentenced to death and prosecuted, however, their ideas spread in many nations and contributed to the emergence of a new social and economic class.

The areas under Protestant influence became much more active economically and shared different social values that still remains today.

If one is to visit North and South Europe, it will turn evident that the social and economical differences are still strong.
