Sidon was the site of an ancient Christian community, dating to its earliest days.
With the conquest of the last Crusader bastion in Acre by the Mamelukes in 1291, the Christian community in Sidon largely vanished.
They united ecclesiastically with the Roman Church under the administration of Euthymius II Karmah, Melkite Patriarch of Antioch.
Initially it was united with the archeparchy of Tyre; the two locations were separated in the mid-eighteenth century (approximately 1752).
On 18 November 1964 the eparchy was elevated to the rank of archeparchy by Pope Paul VI.
