Tatikios or Taticius (Greek: Τατίκιος, c. 1048 – died after 1110) was an Eastern Roman general of Turkish origin during the reign of Alexios I Komnenos.
At the end of the year Tatikios was recalled and sent to fight the Pechenegs, who were assisting the heretical Manichaeans in revolt against Alexius, near Philippopolis.
However, Tatikios was ordered to accompany the Crusaders across Anatolia, both as a guide and also to ensure that any former Byzantine territory re-captured was returned to the Empire.
During the siege of Antioch, Raymond of Aguilers writes that Tatikios advised the Crusaders to disperse and capture the surrounding countryside before attacking the city itself, which would also help them avoid a famine (this advice was ignored).
Bohemund, on the other hand, spread the rumour that Tatikios was a coward and a traitor, and had fled the army never intending to return, despite his promises to bring back reinforcements and provisions from Constantinople.
More conclusively, on 4 March 1098, a few weeks after the departure of Tatikios, a fleet bearing food supplies and siege materials for the crusader army outside Antioch arrived at the port of St Simeon.
[4] The modern historian Peter Frankopan suggests that Alexius was by now confident enough in the established links between Byzantium and the leaders of the crusade to retain his liaison officer in Constantinople for other duties.
Anna also tells the story that Tatikios and Alexius were playing polo when the general was thrown from his horse and landed on the emperor.
Although the office of Grand Primicerius (megas primikerios) was usually held by a eunuch, some records suggest Tatikios had descendants who were members of a powerful noble family in the 12th century, including another general, prominent at the Battle of Sirmium, under Manuel I Comnenus.
