History 

Thessaloniki was established by King Cassander of Macedon, friend of Alexander the Great in the fourth century B.C. He named the city after the sister of Alexander the Great, princess Thessalonike, which in Greek means victory over Thessaly. 

From late antiquity to the late Middle Ages (330AD-1430AD) it was the second most important city of Byzantine Empire. Then Thessaloniki faced many invasions from enemies such as the Avaroi, Bulgars and others. In the year 1204, the crusaders conquered Thessaloniki and created the Kingdom of Thessalonica. Later it was liberated by Byzantines and then sold to the Republic of Venice but the year 1430, it was conquered by the Ottoman Empire. 

Thessaloniki was a part of Ottoman Empire for approximately 500 years and in 1912 it became part of Greece when Greece acquired Macedonia following the Balkan Wars. Many famous people have lived or were born here, such as the Roman statesman and philosopher Cicero, many saints like Cyril and Methodius, who invented the Cyrillic alphabet, and Saint Demetrius, who is the patron saint of the city, and many politicians, such as the founder of modern-day Turkey, Mustafa Kemal Atatürk. Most of the city was completely destroyed in a large fire in 1917 and was rebuilt in the 1920s. Thessaloniki was place to both the Salonica and Macedonian fronts during World War 1, this fronts were made of French, Serbian, English, Italian, and a Russian division. This fronts were key in 1918 to the Entente victory over both Bulgaria and Austria. It was later occupied by Nazi Germany during the Second World War, during the Greek Invasion.
