The four events significant in the ascent of Christianity were:

1. The Crusades: a squence of religious wars authorized by the Roman Catholic Church in the period of 11th-18th centuries.

2. The Inquisition: a judicial institution that was organized in the 13th century by the papacy and sometimes by governments. Their official goal was to contest heresy.

3. Schism: After a break between Rome (Rome I) and Constantinople, Byzantium (Rome II) the quarrel was so intensive that a great Schism took place in 1054. Christianity was divided between the Roman Catholic Church and the Greek Orthodox Church.

4. Reformation: Scholars began to question the Roman Catholic Church’s teaching and the administration of the church by its leaders.The printing press was one important reason why there was an appeal for more reliance on the Bible. The result of this was the beginning of the Protestant Reformation.
