Nicaea, Punjab
Nicaea or Nikaia () was a city in what is now the Punjab, one of the two cities founded by Alexander the Great on opposite sides of the Hydaspes river. The second city founded by Alexander on the Hydaspes was Bucephala. It was at Nicaea or Bucephalia, which appears to have been on the opposite bank, that Alexander (according to Strabo) built the fleet which Nearchus subsequently commanded, the country in the immediate neighbourhood having abundance of wood fit for shipbuilding. Following the Battle of the Hydaspes, Alexander founded two cities. One of the sites of the battle he  named Alexandria "Niceae" meaning "Victory". The site of that city is still undetermined. Any attempt to find the ancient battle site is doomed, because the landscape has changed considerably. A reference to Nicaea may appear in the Mūlasarvāstivāda Vinaya, a Buddhist text of the early centuries CE. This text refers to two cities called Ādirājya ("Place of the First Kingship") and Bhadrāśva ("Place of the Good Horse") located on the Vitastā (i.e., Hydaspes) River along the road from Gandhāra to Mathurā. The Buddhists attributed these two cities to the mythical king Mahāsammata, but some modern scholars propose to identify them  as the two cities founded by Alexander the Great, Nicaea and Bucephala. A number of candidates have been put forward for the location:
