Bilge Qaghan vs Toghrul Beg

After the Eastern Turkic Khaganate was destroyed by the Tang dynasty in 630, Bilge Qaghan, with the help of his brother Kul Tigin and vizier Tonyukuk, revived the khaganate. He defeated the Tang and their allies, re-establishing Turkic independence.

Bilge Qaghan led a campaign against the Tang and their Turkic allies, defeating them at the Irtysh River. This victory secured the khaganate's western borders and demonstrated the military prowess of the revived Turkic state.

Bilge Qaghan negotiated a peace treaty with the Tang dynasty, ending decades of conflict. The treaty established the borders between the two empires and allowed for trade and diplomatic exchanges, bringing stability to the region.

Bilge Qaghan commissioned the Orkhon inscriptions, monumental stelae inscribed with runic Turkic script. These inscriptions, written by Tonyukuk and later by Bilge's son, recorded the history and achievements of the Turkic Khaganate, providing a key source for Turkic history.

Bilge Qaghan was poisoned by a minister, possibly on the orders of the Tang court. His death led to a period of instability and decline for the Eastern Turkic Khaganate, which eventually fell to the Uyghurs in 744.

Toghrul Beg led the Seljuk Turks to victory over the Ghaznavid Empire at Dandanaqan in Khorasan. This defeat forced the Ghaznavids to retreat eastward, granting the Seljuks control of Khorasan and establishing their power base in Persia.

Toghrul Beg launched a major raid into Byzantine Anatolia, reaching as far as the city of Manzikert. Although he did not capture the city, the campaign demonstrated Seljuk military strength and foreshadowed future conflicts that would lead to the Battle of Manzikert in 1071.

Toghrul Beg entered Baghdad at the invitation of the Abbasid Caliph al-Qa'im, who sought protection from the Buyid dynasty. Toghrul deposed the Buyid ruler, married the caliph's daughter, and was granted the title 'Sultan', becoming the de facto ruler of the Islamic world.

Toghrul's half-brother Ibrahim Inal rebelled against his authority, allying with the Fatimid Caliphate. Toghrul defeated and executed Ibrahim Inal, consolidating his power and eliminating a major internal threat to Seljuk unity.
