Answer:
it was based on a power struggle.
Step-by-step explanation:
The great schism of 1054 was largely responsible for dividing Catholic churches into western and eastern. This event had different motives from the Great Schism of 1378, which was established as a power struggle that lasted for three decades.
The great schism of 1378 occurred after the death of Pope Gregory XI. This schism is also known as the papal schism. This is because after the death of Gregory XI there was a disagreement with the choice of the new pope. This led different groups to elect their own pope, resulting in the creation of three different popes who fought among themselves for the power of the Catholic church in the region.
The popes stormed each other and fought a conflict for three decades, until a council called the "Ecumenical Council of Constance" was established, putting an end to the schism and electing Martin V, as the only pope.
