It is one of the oldest cities and ports of ancient Ionia in the Mediterranean Sea. The original settlement was founded around 3000 BC, and the city has survived through different iterations to this day. It was inhabited by Greek populations from antiquity until the destruction of Smyrna in 1922 and the exchange of populations that followed with the Treaty of Lausanne. In its long history it has changed location twice.
The first location (prehistoric times) was mentioned by Strabo as "Old Smyrna" and the second location was built byAlexander the Great and his descendants (Hellenistic period).Ionians, in about 11th centuryBC, established the League ofIonia. It was later conquered by thePersians and retaken by the Greeks before being subsumed into theRoman Empire. In Roman times it became very prosperous and the Romans honored it three times with the praiseworthy title of "young girl" because of its amazing prosperity.
The term "Catholic Church" was first used in 110 in a letter from St. Ignatius of Antioch to the Church of Smyrna. After the split of the Roman Empire, the area became part of what is now called theByzantine Empire until it was conquered by theOttoman Turks in the 14th century. In 1424, Smyrna was conquered by the Ottomans. However, before and after its occupation, Venetians and Genoese tried several times to include it in their Republics.
As a result of the 1923Treaty of Lausanne, all Greek Orthodox inhabitants of the province weredeported, and İzmir Province was incorporated into the modern republic ofTurkey.
