I have read somewhere that the Crimea war was about an attack or it had its start with the attack of the Church of the Birth of Christ or Nativity.
however both the Russians (as defenders of the Orthodox faith) and France under Napoleon III (pretending to be defenders of the Catholic faith) disagreed with the results
Then in France, Napoleon III was looking for imperial adventure
and in England, they actually thought the Moslems were closer to them than Eastern Orthodox
Catholics and Anglicans and Presbyterians shamefully supported Moslems (and I'm Catholic). Yes there was a political angle behind this (Napoleon III wanting a legacy and both England and France looking for concessions in the Ottoman empire)
