Contemporary period

Following the defeat of the Ottoman Empire in World War I, the victors had, for a time, intended to carve up large parts of Anatolia into respective zones of influence and offered the western regions of Turkey to Greece under the Treaty of Sèvres. On 15 May 1919, the Greek Army landed in Smyrna, but the Greek expedition towards central Anatolia was disastrous for both that country and for the local Greeks of Anatolia. By September 1922 the Greek army had been defeated and the last Greek soldiers left Smyrna on 8 September 1922.

The Turkish Army retook possession of the city on 9 September 1922, effectively ending the Greco-Turkish War (1919–1922). Four days later, on 13 September 1922, a great fire broke out in the city, lasting until 22 September. The fire completely destroyed the Greek and Armenian quarters, while the Muslim and Jewish quarters escaped damage. Estimated Greek and Armenians deaths resulting from the fire range from 10,000 to 100,000 Approximately 50,000 to 400,000 Greek and Armenian refugees crammed the waterfront to escape from the fire and were forced to remain there under harsh conditions for nearly two weeks. The systematic evacuation of Greeks on the quay started on 24 September when the first Greek ships entered the harbor under the supervision of Allied destroyers. Some 150,000 to 200,000 Greeks were evacuated in total. The remaining Greeks were expelled to Greece in 1923, as part of the population exchange between Greece and Turkey, a stipulation of the Treaty of Lausanne, which formally ended the Greco-Turkish War.

The war, and especially the events that took place in İzmir, such as the fire, probably the greatest disaster the city has ever experienced, continue to influence the psyches of the two nations to this day. The Turks have claimed that the Greek army landing was marked from the very first day by the "first bullet" fired on Greek detachments by the journalist Hasan Tahsin and the bayonetting to death of Colonel Fethi Bey and his unarmed soldiers in the city's historic barracks (Sarı Kışla — the Yellow Barracks), for refusing to shout " Zito o Venizelos " ("Long Live Venizelos "). The Greeks, on the other hand, have cited the numerous atrocities committed by the Turkish soldiers against the Greeks and Armenians (locals or hinterland refugees) in İzmir. These include the lynching of the Orthodox Metropolitan Chrysostomos following the recapture of the city on 9 September 1922 and the slaughter of Armenian and Greek males, who were then sent to the so-called labour battalions. The city was, once again, gradually rebuilt after the proclamation of the Turkish Republic in 1923.

In 2020, the city was damaged by the Aegean Sea earthquake and tsunami, which was the deadliest seismic event of that year. 117 people died and 1,034 more were injured in Turkey, all but one of whom were from the city of İzmir.

The city of İzmir is composed of several metropolitan districts. Of these, the district of Konak corresponds to historical İzmir, with this district's area having constituted the city's central "İzmir Municipality" (Turkish: İzmir Belediyesi) until 1984. With the formation of the "İzmir Metropolitan Municipality" (Turkish: İzmir Büyükşehir Belediyesi), the city of İzmir at first grouped together its eleven (initially nine) urban districts – namely Balçova, Bayraklı, Bornova, Buca, Çiğli, Gaziemir, Güzelbahçe, Karabağlar, Karşıyaka, Konak, and Narlıdere – and later consolidated them with an additional nine of the province's districts outside the city proper. In 2013, the passing of Act 6360 established all thirty of İzmir Province's districts as part of İzmir's metropolitan area.
