On September 335, the Roman Emperor Constantine allowed pilgrims to visit the tomb of Jesus Christ in Jerusalem.
At the beginning of his reign, Constantine, of course, was a pagan, but then he converted to Christianity.
According to legend, before the decisive battle, the Cross of the Lord appeared to him in a dream and the emperor won. Christianity soon became the dominant religion of ancient Rome.
Constantine asked his mother, Empress Elena, to go to Jerusalem and oversee the search for the tomb of Christ, and then the construction of the Church of the Holy Sepulchre over the grave.
Today, Constantine the Great is revered as one of the saints of the Catholic Church.
