Pope Callixtus I, also called Callistus I, was the bishop of Rome from c. 218 to his death c. 222 or 223. He lived during the reigns of the Roman emperors Elagabalus and Alexander Severus. Eusebius and the Liberian catalogue list his episcopate as having lasted five years (217–222). In 217, when Callixtus followed Zephyrinus as Bishop of Rome, he started to admit into the Church converts from sects or schisms. He was martyred for his Christian faith and is venerated as a saint by the Catholic Church.
Pope Urban I, also known as Saint Urban (175?–230), was the bishop of Rome from 222 to 23 May 230. He was born in Rome and succeeded Callixtus I, who had been martyred. It was believed for centuries that Urban I was also martyred. However, recent historical discoveries now lead scholars to believe that he died of natural causes.

The Chapel of Saint Helena is a 12th-century Armenian church in the lower level of the Church of the Holy Sepulchre in Jerusalem, constructed during the Kingdom of Jerusalem. The Armenians call it the Chapel of St. Gregory the Illuminator, after the saint who brought Christianity to the Armenians.
By the 10th century, Christianity had spread throughout much of Europe and Asia. The Church in England was becoming well established, with its scholarly monasteries, and the Roman Church and the Eastern Orthodox Church were continuing their separation, ultimately culminating in the Great Schism.
Christianity in the 12th century was marked by scholastic development and monastic reforms in the western church and a continuation of the Crusades, namely with the Second Crusade in the Holy Land.
