Thessaloniki was founded in 315 BC by King Cassander of Macedonia. It rapidly became a very important center and one of the major cities of the kingdom during the Hellenistic Era with limited political autonomy. The city was named after the sister of Alexander the Great, Thessalonike.
In 168 BC it became part of the Roman republic and was further developed into an important trade center connecting Europe with Asia through the Roman Via Egnatia. During the first century AD and afterwards, the city became one of the first early Christian centers after Paul the Apostle preached here and laid the foundations for a new religion.
