Ghiyāṣ ad-Dīn Muḥammad ibn Sām (Persian: غیاثالدین محمد بن سام), commonly referred to as Ghiyāṣ ad-Dīn Ghōrī, was a ruler of the 12th century Ghorid dynasty whose realm encompassed Khorāsān and extended into northern and central India all the way to Bengal.
He fought with the Khwarezmid Empire over the lordship of the region. He occupied Herat in 1176 and went on to establish control over most of what is now Afghanistan and surrounding areas by 1200, in the West as far as Bastam. Shahab-ud-din Muhammad Ghori, his brother helped manage and expand the eastern part of the empire, as far as Bengal, and served Ghiyāṣ ad-Dīn Muḥammad Ghori with utmost loyalty and deference. Ghiyāṣ ad-Dīn Muḥammad Ghori died in 1202–03 and was succeeded by his brother Shahab-ud-din Muhammad Ghori.
