Alexios I Komnenos, Emperor of the Byzantine Empire, called upon Western European Christians to help him defeat the Seljuk Turks in what eventually became the First Crusade.
Hardly, it was the Byzantine Church who appealed to the pope for help.
Yes, the migration of the Seljuk Turks significantly contributed to the conditions that led to the First Crusade. Their expansion into the Byzantine Empire and the subsequent defeat of Byzantine forces at the Battle of Manzikert in 1071 weakened Byzantine control over Anatolia, prompting a call for help from the Byzantine Emperor Alexios I. This appeal for aid ultimately led to Pope Urban II's call for the First Crusade in 1095, as Western Christians sought to reclaim Jerusalem and aid their Eastern Christian counterparts. The Seljuk Turks' presence thus played a crucial role in the geopolitical landscape that catalyzed the Crusade.
The Seljuk Turks' expansion into Byzantine territory and their capture of Jerusalem in the late 11th century heightened tensions between Christians and Muslims. Their military victories, particularly the defeat of the Byzantine Empire at the Battle of Manzikert in 1071, prompted Byzantine Emperor Alexios I to seek help from the West. This request for assistance ultimately led Pope Urban II to call for the First Crusade in 1095, with the objective of reclaiming Jerusalem and aiding the Byzantines against the Seljuks.
At the request of the Byzantine Emperor Alexius Comnenus, Pope Urban II called for knights from western Europe to come and help the Byzantines drive the Seljuk Turks out of Palestine.
Pope Urban II granted the Byzantine emperor help against the Seljuk Turks in order to liberate churches of God in eastern regions. Pope Urban II passed away before receiving news of the fall of Jerusalem.
Pope Urban II (1088-1099) called for the Christians to defeat the Turks. This is known as the first crusade and the war for the liberation of the Holy Land.
the Crusades originally had the goal of recapturing Jerusalem and the Holy Land from Muslim rule and their campaigns were launched in response to a call from the Christian Byzantine Empire for help against the expansion of the Muslim Seljuk Turks into Anatolia.
The Seljuks were not actually that important to Palestine. They conquered the territory and administered it until the Crusader States removed their control. The Seljuks did not build any impressive structures in Palestine, move any important populations into or out of Palestine, or help to define any Palestinian national identity.
The Byzantine Emperor sought help from the European Christian kingdoms when the Turks took over.
Dermot McMurrough invited them, to help him regain his throne in Ireland. They came in the year 1169.
The eastern part of the Roman empire fell in 1453 to the Ottoman Turks who took Constantinople. Prior to this the Eastern Roman Empire had gradually been loosing territory to successive invaders: the Arabs had taken the Middle East south of Turkey and Egypt, the Bulgars, Serbs and Croats had taken the Balkans and the Seljuk Turks had taken a big chunk of Turkey. The Ottoman Turks took over form the Seljuk Turks, completed the conquest of Turkey and dealt the final blow.
