Thessaloniki

The city was founded in 315 BC by Cassander of Macedon, who named it after his wife Thessalonike, daughter of Philip II of Macedon and sister of Alexander the Great. It was built 40 km southeast of Pella, the capital of the Kingdom of Macedonia. An important metropolis by the Roman period, Thessaloniki was the second largest and wealthiest city of the Byzantine Empire. It was conquered by the Ottomans in 1430 and remained an important seaport and multi-ethnic metropolis during the nearly five centuries of Turkish rule, with churches, mosques, and synagogues co-existing side by side. From the 16th to the 20th century it was the only Jewish-majority city in Europe. It passed from the Ottoman Empire to the Kingdom of Greece on 8 November 1912. Thessaloniki exhibits Byzantine architecture, including numerous Paleochristian and Byzantine monuments, a World Heritage Site, and several Roman, Ottoman and Sephardic Jewish structures.

In 1423, Despot Andronikos Palaiologos ceded it to the Republic of Venice with the hope that it could be protected from the Ottomans who were besieging the city. The Venetians held Thessaloniki until it was captured by the Ottoman Sultan Murad II on 29 March 1430. Thus began 500 years of Ottoman Turkish rule in Thessaloniki/Selânik, which would profoundly shape the city's unique multicultural character and urban architecture.

Thessaloniki was also a Janissary stronghold where novice Janissaries were trained. In June 1826, regular Ottoman soldiers attacked and destroyed the Janissary base in Thessaloniki while also killing over 10,000 Janissaries, an event known as The Auspicious Incident in Ottoman history. In 1870–1917, driven by economic growth, the city's population expanded by 70%, reaching 135,000 in 1917.

The name Σαλονίκη Saloníki is first attested in Greek in the Chronicle of the Morea (14th century), and is common in folk songs, but it must have originated earlier, as al-Idrisi called it Salunik already in the 12th century. It is the basis for the city's name in other languages: Солѹнъ (Solunŭ) in Old Church Slavonic, סאלוניקו (Saloniko) in Judeo-Spanish (שאלוניקי prior to the 19th century) סלוניקי (Saloniki) in Hebrew, Selanik in Albanian, سلانیك (Selânik) in Ottoman Turkish and Selanik in modern Turkish, Salonicco in Italian, Solun or Солун in the local and neighboring South Slavic languages, Салоники (Saloníki) in Russian, Sãrunã in Aromanian and Săruna in Megleno-Romanian.

At the time of the Roman Empire, about 50 AD, Thessaloniki was also one of the early centres of Christianity; while on his second missionary journey, Paul the Apostle visited this city's chief synagogue on three Sabbaths and sowed the seeds for Thessaloniki's first Christian church. Later, Paul wrote letters to the new church at Thessaloniki, with two letters to the church under his name appearing in the Biblical canon as First and Second Thessalonians. Some scholars hold that the First Epistle to the Thessalonians is the first written book of the New Testament.

In English, the city can be called Thessaloniki, Salonika, Thessalonica, Salonica, Thessalonika, Saloniki, Thessalonike, or Thessalonice. In printed texts, the most common name and spelling until the early 20th century was Thessalonica (), matching the Latin name; through most of rest of the 20th century, it was Salonika (). By about 1985, the most common single name became Thessaloniki. The forms with the Latin ending -a taken together remain more common than those with the phonetic Greek ending -i and much more common than the ancient transliteration -e.

The city was founded around 315 BC by the King Cassander of Macedon, on or near the site of the ancient town of Therma and 26 other local villages. He named it after his wife Thessalonike, a half-sister of Alexander the Great and princess of Macedonia as daughter of Philip II. Under the kingdom of Macedonia the city retained its own autonomy and parliament and evolved to become the most important city in Macedonia. Nonetheless, Pella remained the capital of Macedon until its fall.
