Which wast Christianity's most important victory over the aggressive invading armies of Islam in defence of Christendom?

Please feel free to mention any I missed.
Personally I think the Battle of Tours was the most important as that is the first time rampaging Muslim armies had been stopped and beaten in western Europe. Christian Spain, Northern Africa and eastern parts of the eastern Roman empire already had already been conquered.









Battle of Tours (Franks)
Battle of Azurth (Norman English 3rd crusade)
The Liberation of Jerusalem (First crusaders Franks)
Battle of Montgisard (Kingdom of Jerusalem& Templars)
Battle of Lepanto ( Holy League)
The Battle of Vienna (Holy Roman Empire, kingdom of Poland, Italian cities)
Siege of Granada (Spainish reconquista)
