In 1173, Ghiyath invaded Ghazni and defeated the Oghuz Turks, who had taken the city from the Ghaznavids. He then installed his brother Mu'izz al-Din as the ruler of Ghazni. Two years later, he seized Herat and Pushang from its Seljuq governor, Baha al-Din Toghril. Shortly thereafter, the ruler of Sistan, Taj al-Din Harb ibn Muhammad, acknowledged the sovereignty of Ghiyath, and so did the Oghuz Turks controlling Kirman.
