It was built by Antigonus, perhaps about 310 B.C., and was called by him Antigonia Troas.
Antigonus fixed his capital at the old Phrygian town of Celaenae, and the famous cities of Nicaea and Alexandria Troas owed to him their first foundation, each as an Antigonia; they were refounded and renamed by Lysimachus (301-281 B.C.).
Alexandretta), Samaria, Pella (the later Apamea), Carrhae, &c. Antigonus founded Antigonia, which was absorbed a few years later by Antioch, and after the fall of Antigonus in 301, the work of planting Syria with Greek cities was pursued effectively north of the Lebanon by the house of Seleucus, and, less energetically, south of the Lebanon by the house of Ptolemy.
But the first western sovereign practically to recognize the importance of the district was Antigonus, who began to build a city, Antigonia, on the Kara Su a few miles north of the situation of Antioch; but, on his defeat, he left it to serve as a quarry for his rival Seleucus.
Antigonus built the city (316 B.C. ?) on an old deserted site, and soon afterwards Lysimachus changed its name from Antigonia to Nicaea, calling it after his wife.
