Gregory Pakourianos (, Grigol Bakurianis-dze; , Gregorios Pakourianos; , Grigor Bakurian; ) (died 1086) was a Byzantine politician and military commander. He was the founder of the Monastery of the Mother of God Petritzonitissa in Bachkovo and author of its typikon. The monks of this Orthodox monastery were Iberians. Life Background Gregory's origins are a matter for scholarly dispute. He is believed to have hailed from the region of Tao or Tayk, which had been ruled by Georgian Bagratids of kouropalatate of Iberia, later annexed by the Byzantines to the theme of Iberia in 1001. According to Anna Comnena Gregory was "descended from a noble Armenian family." According to N. Aleksidze, the only source that indicates his Armenian origin is Anna Comnena who was only three years old when Gregory died.<ref>Nikoloz Aleksidze.

Gregory himself proclaimed that he belonged to "the glorious people of the Iberians" and insisted his monks to know the Georgian language. Under Byzantine suzerainty, the population of Upper Tao identified itself as 'Georgian'. The élite of Tao (Basil Bagratisdze, P'eris Jojikisdze, Abas and Grigol Bakurianisdze) regarded Georgia as 'our country' and strove for its spiritual, cultural and political prosperity. Thus, he, like other representatives of the elite from the Tao region, considered Georgia his homeland and strove for its spiritual, cultural and political prosperity. Taking into account all the evidence available on Pakourianos, the scholar Nina G. Garsoïan proposed that "the most likely explanation is that [the Pakourian family] belonged to the mixed Armeno-Iberian Chalcedonian aristocracy, which dwelt in the border district of Tayk/Tao." Anna Comnena described Pakourianos as having a tiny frame but being a mighty warrior. Byzantine service Since 1060 Gregory served in Byzantine army. In 1064 he had achieved a significant position among the Byzantine military aristocracy, but failed at defending Ani against the Seljuk leader Alp Arslan, King Bagrat IV of Georgia and Albanian King Goridzhan in the same year. Since 1071 he was appointed as a Strategos (governor) of the theme of Iberia. As the Seljuk advance forced the Byzantines to evacuate the
