Tatikios or Taticius (, c. 1048 - died after 1110) was an Eastern Roman general of Turkish origin during the reign of Alexius I Comnenus. His name is also rendered as Tetigus, Tatizius, Tatitius, Tatic, or Tetig. Origins and early life The father of Tatikios was a "Saracen", probably meaning a Turk, who was captured by Alexius' father John Comnenus and who served as a slave in the Comnenus household. Tatikios and Alexius grew up together. Tatikios is described as an oikogenes of Alexius (that is, "from the same house"). In 1078, before Alexius became emperor, Tatikios accompanied him in battle against his rival Nicephorus Basilacius. During this campaign Tatikios discovered Basilacius' plans for an ambush. When Alexius became emperor in 1081 Tatikios held the office of megas primikerios in the imperial household. Later that year he commanded the "Turks living around Ochrida", perhaps Hungarians at the Battle of Dyrrhachium against Robert Guiscard. Military and political career In 1086 Tatikios was sent to Nicaea in an attempt to recapture it from the Seljuks. He was forced to retreat when he learned that Seljuk reinforcements were on their way. Alexius sent Tatikios back with naval assistance from Manuel Boutoumites. Although Tatikios was able to defeat Abu'l Qasim, in Bithynia, he could not recapture the city. 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. In 1087 Tatikios commanded the Byzantine right wing in the Battle of Dristra against the Pechenegs, and in 1090 he defeated a small force of 300 Pechenegs while leading the Archontopouloi tagma against them. In early 1094, Tatikios was placed in charge of guarding Alexius' tent at Pentegostis. Here he discovered the plot of Nikephoros Diogenes, son of the former emperor Romanus IV Diogenes, to kill the emperor. Nicephorus was an old friend of Alexius and Tatikios and Alexius was reluctant to punish him, but it was clear that Nicephorus was ambitious for the throne. Nicephorus was exiled and was eventually blinded. Later in 1094, Tatikios attended the synod of Blachernae which condemned Bishop Leo of Chalcedon, presumably performing some function of security. In the records of this synod Tatikios is given the court title of protoproedros. In 1095 Tatikios accompanied Alexius in the campaign against the Cumans. Role during the First Crusade In 1096 Tatikios defended Constantinople from
