Hephthalite Empire
Around 460 CE, the Hephthalites, also known as the White Huns, invaded the region from Central Asia, forcing the ruling family of nearby Taxila to seek refuge in Sialkot. Sialkot itself was soon captured, and the city was made capital of the Hephthalite Empire around 515, during the reign of Toramana. During the reign of his son, Mihirakula Gujjar, the Hephthalite Empire reached its zenith. The Hepthalites were defeated in 528 by a coalition of princes led by Prince Yashodharman
