Abgar V, also known as Ukkama, was an Arab monarch who ruled the kingdom of Osroene from his capital at Edessa during the 1st century. He is traditionally celebrated as one of the earliest Christian kings, having reportedly embraced the faith through the work of the disciple Thaddeus. According to long-standing Christian traditions, he sought healing from Jesus through a written correspondence, an event that became a foundational narrative for several Eastern Christian traditions.
