c. A decline in the power of the Catholic Church and rise of anti-Semitism
One significant impact of the Bubonic Plague on medieval Europe was a decline in the power of the Catholic Church and an increase in anti-Semitism. The Church's inability to provide answers or relief during the pandemic led to a loss of faith for some people. Additionally, Jews were often scapegoated and blamed for the plague, leading to increased persecution and violence against them.
