Emperor Heraclius returns the True Cross, one of the holiest Christian relics, to Jerusalem.

Heraclius was Byzantine emperor from 610 to 641. His rise to power began in 608, when he and his father, Heraclius the Elder, the Exarch of Africa, led a revolt against the unpopular emperor Phocas.

According to Christian tradition, the True Cross is the real cross on which Jesus of Nazareth was crucified.

In religion, a relic is an object or article of religious significance from the past. It usually consists of the physical remains or personal effects of a saint or other person preserved for the purpose of veneration as a tangible memorial. Relics are an important aspect of some forms of Buddhism, Christianity, Islam, shamanism, and many other religions. Relic derives from the Latin reliquiae, meaning "remains", and a form of the Latin verb relinquere, to "leave behind, or abandon". A reliquary is a shrine that houses one or more religious relics.

Jerusalem is a city in the Southern Levant, on a plateau in the Judaean Mountains between the Mediterranean and the Dead Sea. It is one of the oldest cities in the world, and is considered holy to the three major Abrahamic religions—Judaism, Christianity and Islam. Both Israel and Palestine claim Jerusalem as their capital city; Israel maintains its primary governmental institutions there, while Palestine ultimately foresees it as its seat of power. Neither claim is widely recognised internationally.
