Briefly summarize how christianity split into catholic and protestant

Protestantism is one of the main branches of Christianity. Approximately 801 million Christians, or 36.7% of the 2,184 million Christians, are Protestants. The Protestants were originally from Christian groups who claim that the Catholic Church was incurring numerous theological errors, they separated from it in the sixteenth century, in a process called the Protestant Reformation. Since then, Protestants have denied papal supremacy and the efficacy of the sacraments. Most Protestants believe in the priesthood of all believers, salvation only by faith and not good deeds and the supreme authority of the Bible over the sacred tradition.

It is known as the Protestant Reformation, or simply the Reformation, the Christian religious movement, initiated in Germany in the sixteenth century by Martin Luther, which led to a schism of the Catholic Church to give rise to numerous churches grouped under the denomination of Protestantism.

The Reformation had its origin in the criticisms and proposals with which various religious, thinkers and European politicians sought to cause a profound and widespread change in the customs and customs of the Catholic Church, in addition to denying the jurisdiction of the pope over all Christendom. The movement will later receive the name of Protestant Reformation, for its initial intention to reform Catholicism in order to return to a primitive Christianity, and the importance of the Speyer Protest, presented by some German princes and cities in 1529 against an edict of the Emperor Charles V tending to repeal the religious tolerance that had previously been granted to the German principalities.
