The Monastery of Great Lavra is the first monastery built on Mount Athos, on the Athos peninsula in northeastern Greece. It is located on the southeastern foot of the Mount at an elevation of 160 metres (170 yd). The founding of the monastery in AD 963 by Athanasius the Athonite marks the beginning of the organized monastic life at Mount Athos. At the location of the monastery, there was one of the ancient cities of the Athos peninsula, perhaps Akrothooi, from which the sarcophagi of the monastery that are in the oil storage house come. The history of the monastery is the most complete compared to the history of the other monasteries, because its historical archives were preserved almost intact. It is possible that the study of these archives may contribute to the completion of the knowledge of the history of other monasteries, whose archives were partially or completely lost.

Nikephoros II Phokas, Latinized Nicephorus II Phocas, was Byzantine emperor from 963 to 969. His career, not uniformly successful in matters of statecraft or of war, nonetheless greatly contributed to the resurgence of the Byzantine Empire during the 10th century. In the east, Nikephoros completed the conquest of Cilicia and retook the islands of Crete and Cyprus, opening the path for subsequent Byzantine incursions reaching as far as Upper Mesopotamia and the Levant; these campaigns earned him the sobriquet "pale death of the Saracens".
