Agalassoi
The Agalassoi were a dignified, illustrious and powerful tribe that lived in modern Pakistan in the lower Indus Valley at the time of Alexander the Great. During Alexander's invasion of India, the Agalassoi fought bravely in battle with the Macedonian army. The citizen infantry, numbering about 40,000 and 2,000 cavalry after a brave resistance to Alexander, cast themselves with their wives and children into flames, the first known Jauhar and Sākā in Indian history. They have been identified as Agarwals of today.
