Great Seljuk State
Who Were the Seljuks?
The Great Seljuk State was a major Turkish state established during the Middle Ages that significantly shaped history. It derived its name from Selçuk Bey, a chieftain of the Oghuz Turks. The Seljuks made great advances in science, art, and governance. They were not only warriors but also placed great importance on culture and education by building madrasas, mosques, and libraries.
Where and When Were They Established?
The Great Seljuk State was established in 1040 after the Battle of Dandanakan. They established dominance over regions corresponding to modern-day Iran, Iraq, Syria, Azerbaijan, and parts of Central Asia. The founder of the state was Tuğrul Bey. Tuğrul Bey, together with his brother Çağrı Bey, founded the state and gradually extended their rule as far as Anatolia.
How Did They Live?
Initially nomadic, the Seljuks adopted a settled lifestyle after establishing their state. Palaces, madrasas (schools), mosques, and bazaars were constructed in major cities. The population engaged in crafts, agriculture, animal husbandry, and trade. In addition to Turkish, Arabic and Persian were also used.
The Importance They Placed on Science and Art
The Seljuks made significant progress not only in warfare but also in science. By establishing madrasas, they expanded the educational system. The famous vizier Nizam al-Mulk founded the Nizamiye Madrasa in Baghdad, which became one of the largest educational institutions of its time. They also placed great emphasis on architecture, constructing large and ornate buildings.
What Was the Great Seljuk Army Like?
The Seljuk army consisted of powerful cavalry units. Mounted troops could move swiftly against enemies. The sultan commanded the army and directed military campaigns. One of the most important commanders, Alp Arslan, defeated the Byzantine army at the Battle of Manzikert in 1071, opening the gates of Anatolia to the Turks. This victory is one of the turning points in Turkish history.
