History of Sagala

The city of Sagala appears in the accounts of Alexander the Great`s conquests of India. It is said that after crossing the Hydraotes( the Ravi River) Alexander joined Porus and 5,000 Indian soldiers and laid seige to Sagala. Alexander laid seige to the city and its inhabitants were killed.
During the Sunga Period, Pusyamitra Sunga is believed to have expanded northwest as far as Sagala. In the Indo- Greek period, the Indo- Greeks repelled the Sungas and Sagala was used as a capital by them.
Though Indo-Greek cities were designed along Greek architectural lines, Sagala was clearly an Indian city. the best description of Sagala comes from the Milinda Panha, a dialogue between king Menander and the Nagasena(a buddhist monk). The rule of King Meander bear testimony to his benevolance. He was considered as a Chakravartin - King of the Wheel or literally Wheel-Turner in Sansrkit. He was very efficient that, as a king, it was he who turned the wheels of Sagala.
