Taj ad-Din Yildiz

Taj al-Din Yildiz (also spelled Yaldiz, Yildoz, and Yalduz, Persian: تاج‌الدین ییلدز‎‎) was a Turkic slave commander of the Ghurids, who, after the death of Sultan Mu'izz al-Din Muhammad, became the ruler of Ghazni, while, however, still recognizing Ghurid authority.

After the death of Sultan Mu'izz al-Din Muhammad, two factions arose in the Ghurid Empire; a faction of Turkic ghulams, who supported Mu'izz's nephew Ghiyath al-Din Mahmud, while the other faction consisted of native Iranian soldiers, who supported the Ghurid ruler of Bamiyan, Baha al-Din Sam II.

In 1208, the semi-independent Ghurid governor of India, Qutb-ud-din Aibak, attacked and occupied Ghazni, but was defeated by Yildiz forty days later.

In 1214, Yildiz killed Ala al-Din Atsiz, and put the latter's cousin Ala al-Din Ali on the Ghurid throne as his puppet.
