Tansu Çiller is a Turkish academic, economist, and politician who served as the 22nd Prime Minister of Turkey from 1993 to 1996. She is Turkey's first and only female prime minister to date. As the leader of the True Path Party, she went on to concurrently serve as Deputy Prime Minister of Turkey and as Minister of Foreign Affairs between 1996 and 1997.

Her premiership preceded over the intensifying armed conflict between the Turkish Armed Forces and the PKK, resulting in Çiller's enacting numerous reforms to national defense and implementing the Castle Plan. With a better equipped military, Çiller's government was able to persuade the United States and the European Union to register the PKK as a terrorist organization. However, Çiller was responsible for war crimes and crimes against humanity perpetrated against the Kurdish people by the Turkish military, security forces, and paramilitary.

Shortly after winning the 1994 local elections, large-scale capital flight due to the lack of confidence in Çiller's budget deficit targets led to the Turkish lira and foreign currency reserves' almost collapsing. Amid the subsequent economic crisis and austerity measures, her government signed the EU-Turkey Customs Union in 1995. Her government was alleged to have supported the 1995 Azeri coup d'état attempt and presided over an escalation of tensions with Greece after claiming sovereignty over the Imia/Kardak islets.
