Quick Summary

Chaghri Beg was a key figure in the establishment of the Seljuq dynasty. Alongside his brother Toghril Beg, he led Turkic tribes from Central Asia into southwestern Asia during the 11th century. After converting to Islam, they gained influence and eventually defeated the Ghaznavids at the Battle of Dandanaqan in 1040. This victory led to Chaghri controlling Khorasan, while Toghril focused on conquering the Iranian plateau. The Seljuqs eventually established a vast empire, asserting political mastery over the Abbasid caliphate in Baghdad and marking the beginning of significant Turkic power in the Middle East.12
