Immortals (Byzantine Empire)
The Immortals (Greek: Ἀθάνατοι, Athanatoi) were one of the elite tagmata military units of the Byzantine Empire, first raised during the late 10th century. The name derives from a- ("without") + thanatos ("death").

The Athanatoi were a body of young men of noble status that was originally raised by John I Tzimiskes (r. 969-976) in 970 for his war with the Rus', where they played a decisive role in the battles before Preslav and during the Siege of Dorostolon. The unit was commanded by a domestikos, as with most of the other tagmata (the professional standing regiments), and on campaign camped near the imperial bodyguard, the Hetaireia. The contemporary historian Leo the Deacon describes the Athanatoi as heavily armoured shock cavalry, "sheathed in armour" or as "armed horsemen adorned with gold". Tzimiskes' unit was probably disbanded shortly after his death, since it does not appear again in the sources.
The name of the Athanatoi was revived under the Emperor Michael VII (r. 1071–1078), when his minister Nikephoritzes reorganised the army. This reorganisation was part of an effort to address a major military crisis for the Empire following the disastrous defeat suffered by the Byzantines against the Seljuk Turks at the Battle of Manzikert in 1071. The Seljuks had subsequently overrun most of Asia Minor, which had provided the main recruiting ground for the pre-Manzikert army. As part of the reorganisation process, the remnants of the provincial troops of the Eastern themata (military provinces) were brought together as the Immortals, providing a new tagma. The new Immortals may have been cavalry, like the bulk of the old Byzantine field army, but this is not certain.
The Byzantine historian Nikephoros Bryennios the Younger records that the Immortals numbered 10,000, but this is most likely an allusion to the old Persian Immortal Guard. The new unit fought under the future emperor Alexios I Komnenos in the Battle of Kalavrye (1078) against the rebel general Nikephoros Bryennios the Elder, and are mentioned in the wars against the Pechenegs in the 1090s, but disappear thereafter, along with another contemporary creation, the Archontopouloi.
