context_page_description: Nicaea or Nicea was an ancient Greek city in northwestern Anatolia and is primarily known as the site of the First and Second Councils of Nicaea, the Nicene Creed, and as the capital city of the Empire of Nicaea following the Fourth Crusade in 1204, until the recapture of Constantinople by the Byzantines in 1261.
  The ancient city is located within the modern Turkish city of İznik, and is situated in a fertile basin at the eastern end of Lake Ascanius, bounded by ranges of hills to the north and south. It is situated with its west wall rising from the lake itself, providing both protection from siege from that direction, as well as a source of supplies which would be difficult to cut off. The lake is large enough that it could not be blockaded from the land easily, and the city was large enough to make any attempt to reach the harbour from shore-based siege weapons very difficult.
  The ancient city is surrounded on all sides by 5 kilometres of walls about 10 metres high. These are in turn surrounded by a double ditch on the land portions, and also included over 100 towers in various locations.
context_section_description: The place is said to have been colonized by Bottiaeans, and to have originally borne the name of Ancore (Ἀγκόρη) or Helicore (Ἑλικόρη), or by soldiers of Alexander the Great's army who hailed from Nicaea in Locris, near Thermopylae. The later version however was not widespread even in Antiquity. Whatever the truth, the first Greek colony on the site was probably destroyed by the Mysians, and it fell to Antigonus I Monophthalmus, one of Alexander's successors (Diadochi) to refound the city ca. 315 BC as Antigoneia (Ἀντιγονεία) after himself. Antigonus is also known to have established Bottiaean soldiers in the vicinity, lending credence to the tradition about the city's founding by Bottiaeans. Following Antigonus' defeat and death at the Battle of Ipsus in 301 BC, the city was captured by Lysimachus, who renamed it Nicaea (Νίκαια, also transliterated as Nikaia or Nicæa; see also List of traditional Greek place names), in tribute to his wife Nicaea, who had recently died.
  Sometime before 280 BC, the city came under the control of the local dynasty of the kings of Bithynia. This marks the beginning of its rise to prominence as a seat of the royal court, as well as of its rivalry with Nicomedia. The two cities' dispute over which one was the pre-eminent city (signified by the appellation metropolis) of Bithynia continued for centuries, and the 38th oration of Dio Chrysostom was expressly composed to settle the dispute.
  Plutarch, mentioned that Menecrates (Μενεκράτης) wrote about the history of the city.
