In 1054, the Great Schism divided eastern and western Christianity, largely over matters of church leadership true or false

Answer 1

True. The Great Schism of 1054 was indeed primarily a division between Eastern Orthodoxy and Western Roman Catholicism, and one of the key issues was disagreements over church leadership, particularly the authority of the Pope. Other theological and cultural differences also contributed to the schism, but the dispute over the primacy of the papacy was a significant factor.
