European people promised to never again go to war against each other on account of religion.
This was the beginning of a more permanent and rational Religious Tolerance in the West.
Think of it as having built on the principles set forth in the Edict of Nantes and the Treaty of London (1604).
These treaties were signed by the Pope, leaders of Catholic countries, leaders of Protestant countries and Protestant leaders.
Here's what is important about these treaties today ~ they were NOT signed by Jews, Moslems, Christian Orthodox, Hindus, Buddhists, Shintoists or Zen Buddhists, nor by Communists.
That is really interesting..thanks
