Sagala, Śākala, or Sangala was a city in Punjab, which is generally identified as the predecessor of the modern city of Sialkot that is located in what is now Pakistan's northern Punjab province. The city was the capital of the Madra kingdom and it was razed in 326 BC during the Indian campaign of Alexander the Great. In the 2nd century BC, Sagala was made capital of the Indo-Greek kingdom by Menander I. Menander embraced Buddhism after extensive debating with a Buddhist monk, as recorded in the Buddhist text Milinda Panha. Sagala became a major centre for Buddhism under his reign, and prospered as a major trading centre.
