What effect did the dispute between the orthodox and the roman catholic churches in the 11th century have?

The two churches split apart permanently.

Explanation:

The splitting of the churches in Europe in the 11th century happened when Pope Leo IX came to Constantinople to meet the Eastern patriarch to solve the conflict of religion. Both did not agree on matters and excommunicated each other, which led to the Great Schism (split) of 1054. The Great Schism divided Christianity into two-part known as the  Eastern Orthodox and Roman Catholic.

pepin the short[a] (german: pippin der kurze, french: pépin le bref, c. 714 – 24 september 768) was the king of the franks from 751 until his death. he was the first of the carolingians to become king.[b][2]

the younger son of the frankish prince charles martel and his wife rotrude, pepin's upbringing was distinguished by the ecclesiastical education he had received from the monks of st. denis. succeeding his father as the mayor of the palace in 741, pepin reigned over francia jointly with his elder brother carloman. pepin ruled in neustria, burgundy, and provence, while his brother carloman established himself in austrasia, alemannia and thuringia. the brothers were active in suppressing revolts led by the bavarians, aquitanians, saxons, and the alemanni in the early years of their reign. in 743, they ended the frankish interregnum by choosing childeric iii, who was to be the last merovingian monarch, as figurehead king of the franks.
