Bilge Qaghan vs Someshvara I

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.

Someshvara I moved the Western Chalukya capital from Manyakheta to Kalyani (modern Basavakalyan). This relocation shifted the political center of the empire and marked a new phase in Chalukya administration.

Someshvara I built a fortified palace and administrative complex at Kalyani. The fort became the center of Western Chalukya power and a symbol of their authority in the Deccan.

Someshvara I engaged in a prolonged conflict with the Chola king Rajendra II. The war included battles in the Tungabhadra region and resulted in territorial exchanges, with neither side achieving decisive victory.
