Muzaffargarh (Saraiki: مظفر ڳڑھ and Urdu: مظفر گڑھ, lit. 'Fort of Muzaffar') is a city in the province of Punjab, Pakistan. Located on the bank of the Chenab River, it is the capital of the eponymous district. It is the 39th most populous city of Pakistan. The Muzaffargarh region was an agricultural and forested area during the Indus Valley civilization. Then came the Vedic period, which was characterized by the introduction of Indo-Aryan culture into the Punjab province. Over time, several other civilizations came to power in the ancient town and surrounding district: the Kambojas, the Daradas, the Kekayas, the Madras, the Pauravas, the Yaudheyas, the Malavas and the Kurus. After the fall of the Achaemenid Empire in 331 BCE, Alexander the Great marched into the present-day Punjab province with an army of 50,000 men. The Muzaffargarh region was, during different time periods, also ruled by the Maurya Empire, the Indo-Greek kingdom, the Kushan Empire, the Gupta Empire, the White Huns, the Kushano-Hephthalites, and the Turk and Hindu Shahi kingdoms.
