the influential position of comes excubitorum, commander of the palace guard. During this period he married Lupicina; no surviving children are recorded from this marriage. According to contemporary historian Procopius, Lupicina was a barbarian slave who had been Justin's concubine before their marriage. Succession During the night of 8–9 July 518, Anastasius died and his silentarii, a senior servant, summoned Justin and Celer to his deathbed. Celer was the magister officiorum (master of offices) and commander of the palace regiments of the Scholae Palatinae, a force of parade-ground display troops. By morning the event had been announced throughout the capital, Constantinople. The high officials, including John of Cappadocia, the recently appointed Patriarch of Constantinople, were summoned to the Great Palace for the election of a new emperor. Meanwhile, the people gathered in the Hippodrome of Constantinople and awaited the proclamation of the name of the new emperor. Anastasius had died childless but had a host of known relatives.

The name was probably chosen for reasons of respectability. The original Euphemia was a Christian martyr during the Diocletianic Persecution. She was a local saint of Chalcedon and the Council of Chalcedon (451) had taken place in a cathedral consecrated in her name. The selection of this name was an early indication that Justin and Lupicina were fervent Chalcedonian Christians. The population of the capital was supportive because of his strong Chalcedonian position on the fierce Christological debate of the time, in opposition to his predecessor's Monophysite leanings. Emperor Justin cemented his position by assassinating potential opponents, especially anti-Chalcedonian supporters of Anastasius. Both Amantius and Theocritus were
