Step-by-step explanation:
The true effect of the plague in Europe was The Great Schism.
The Great Schism refers to the division within the Catholic Church that occurred in the 14th and 15th centuries. It was partially caused by the devastation and social upheaval caused by the Black Death (plague) in Europe.
