Foundation and Roman Integration

Thessaloniki was founded around 315 BC by King Cassander of Macedon. He named the city after his wife, Thessalonike, who was a half-sister of Alexander the Great. Her name, meaning "victory of Thessalians," marked her birth on the day her father, Philip II, secured a victory with the aid of Thessalian horsemen. The city was established on or near the ancient town of Therma and 26 other local villages. Under the Macedonian kingdom, Thessaloniki maintained its autonomy and parliament, becoming the most important city in Macedonia.

In 168 BC, after the fall of the Kingdom of Macedonia, Thessaloniki came under Roman control. By 146 BC, it was designated the capital of the Roman province of Macedonia. Its location on the Via Egnatia, a major Roman road connecting the Adriatic Sea to Byzantium (Constantinople), and its natural harbor in the Thermaic Gulf, made it a military and commercial hub. The Apostle Paul preached in Thessaloniki around 49 AD, addressing two of his epistles to its inhabitants, establishing it as an early center for Christianity.

Byzantine Era and Ottoman Rule

During the Byzantine Empire, Thessaloniki developed as the second-largest and wealthiest city after Constantinople. The city's walls and numerous Paleochristian and Byzantine monuments, many of which are UNESCO World Heritage sites, reflect this period. Despite attacks by Avars and Slavs in the 6th and 7th centuries, and a sack by Normans in 1185, Thessaloniki continued to grow. In 1204, after the Fourth Crusade captured Constantinople, Thessaloniki became the capital of the Kingdom of Thessalonica, a Latin Empire vassal, before being reclaimed by the Greeks in 1224.

The city fell to the Ottoman Turks in 1430, beginning nearly five centuries of Ottoman rule. During this time, Thessaloniki became an important seaport and a multi-ethnic city where churches, mosques, and synagogues coexisted. A significant influx of Sephardic Jews from Spain in 1492 contributed to the city's diverse character, making it the only Jewish-majority city in Europe from the 16th to the 20th centuries. Thessaloniki remained part of the Ottoman Empire until November 8, 1912, when it was captured by the Greek army during the First Balkan War and ceded to the Kingdom of Greece in 1913.

The best times to visit Thessaloniki are during spring (April to June) and autumn (September to October). During these seasons, the weather is pleasant with temperatures for walking and sightseeing, ranging from 20-25°C (68-77°F). Crowds are also lighter than in the summer months.

Summer (July and August) can be hot, with average daily highs around 33°C (91°F) and high humidity, making midday exploration difficult. Many locals go to the beaches of Halkidiki during this time. Winter (December to February) is mild but can be chilly and rainy, with occasional snow. Some outdoor seating at restaurants may be closed.
