Well I’ll have to go back and read Zoe Oldenburg’s book on the crusades and maybe a couple of others. As to whether it was justified or not they were perhasp at the time.
Why should we as christians have to defend them.The turks(muslims) were a threat to the Byzantine Empire in their move towards Europe wich is one of the reasons for it. We finally defeated them at the Battle of Lepanto in the 16th or 17th century. To celebrate the Christian victory of the Muslims the pope at the time instituted the feast of Our Lady of Victory.
The Mercedian Order was founded to help christians captured by the muslims hence Our Lady of Ransom. Even before the Crusades Charlemagne and others fought against them when they came up from Spain to try and take over France and that.
Had some cousins of my grandmother,the von Lilienschilds who fought in the Crusades according to german records.Some of the family later went on to Lativa and fought in the crusades in the Baltic countries.It was a move to civilize and convert the pagan baltic tribes.
