The Pandyan or Pandian dynasty was an ancient Tamil dynasty, one of the three Tamil dynasties, the other two being the Chola and the Chera). The Pandya King, along with Chera King and Chola King, together were called as Three Crowned Kings of Tamilakam. The dynasty ruled parts of South India from around 600 BCE (Early Pandyan Kingdom) to first half of 17th century CE. They initially ruled their country Pandya Nadu from Korkai, a seaport on the southernmost tip of the Indian Peninsula, and in later times moved to Madurai. Fish being their flag, Pandyas were experts in water management, agriculture(mostly near river banks) and fisheries and they were eminent sailors and sea traders too.
