A short history
Thessaloniki was founded in 315 BC by King Cassander and named after his wife, a half sister of Alexander the Great. It became a major Roman city on the Via Egnatia and later the second city of the Byzantine Empire, leaving many churches now listed by UNESCO. Under Ottoman rule from 1430 it was home to a large Sephardic Jewish community, which was almost entirely destroyed in the Holocaust. A great fire in 1917 burned much of the center, which was rebuilt on a new plan. The city joined Greece in 1912.
