I have a question about the relative power of the Ottomans vs the combined might of their usual Christian opponents in the 16th and 17th centuries. So whenever the Christian Europeans managed to rally behind a single cause they seemed to beat the Ottomans fairly handily. For example the Battle of Vienna and the Battle of Lepanto. So were these victories very lucky flukes or were the combined European powers more powerful than the Ottomans but unable to bring that power to bear because of politically fighting between them?
