Tughril I
Legacy

Sultan Tughril was undoubtedly a military genius. Though his military campaigns inflicted serious damage on the productive forces of many conquered states, they paved the way for the establishment of the first powerful medieval empire of the Turks that linked "the East and the West". The formation of a vast empire objectively led to important changes in socio-economic, political and cultural life. The role of the landowning aristocracy markedly increased. Gradually, a new apparatus of state administration and an imperial system of civil and military administration took shape.

Tughril's conquests had an impact on the lives of not only the people of annexed states, but also the nomads themselves, who participated in the establishment of the new state. Noticeable changes in the life of the Oguz-Turkmen tribes occurred as they settled in Khorasan, Iran, Iraq, Syria, Transcaucasia and Asia Minor. The transition of compact groups of nomads to a semi-settled and sedentary life and agriculture took place. The old tribal ties broke up; feudal relations received a new incentive for further development, although remnants of archaic institutions remained for a long time. The Seljuk nobility began to gradually merge with the feudal aristocracy of the conquered lands.
