Antiocheia Orontou

Antiocheia Orontou is a city in Seleukid Syria which originally served as the Antigonid capital, but was conquered by Seleukos I Nikator. During the conquest the city was sacked, leaving lasting tensions between the Seleukids and the citizens of the city. However by the mid 3rd century BC it was growing a diverse and flourishing city under the Seleukids and old animousities slowly faded.
