The True Cross is the name for physical remnants traditionally believed to be from the cross upon which Jesus was crucified. According to a number of early writers, the Empress Helena, (250–330 AD) mother of Constantine, the first Christian Emperor of Rome, at a date after 312 AD when Christianity was legalized throughout the Empire, travelled to the Holy Land, founding churches and establishing relief agencies for the poor. It was at this time that she discovered the hiding place of three crosses used at the crucifixion of Jesus and the two thieves that were executed with him. By a miracle it was revealed which of the three was the True Cross. Many churches (including Ethiopian Orthodox Church) possess fragmentary remains which are by tradition alleged to be those of the True Cross.
