July 15 marks the anniversaries of two coup attempts that left deep marks on the modern histories of Cyprus and Turkey. Separated by 42 years, the events had very different immediate outcomes, yet both showed how military intervention can reshape political institutions and societies for decades.
The summer of 1974 set the course for Cyprus’s de facto division, which persists today. Tens of thousands of Cypriots were displaced, while missing persons, property claims, displacement and the loss of cultural heritage became enduring consequences of the conflict. The coup also accelerated the collapse of the Greek junta and Greece’s return to civilian rule.
In Cyprus, a coup against President Archbishop Makarios was staged on July 15, 1974, by elements of the Cypriot National Guard and EOKA-B, with the backing of Greece’s military junta. Its ultimate objective was enosis — the union of Cyprus with Greece.
The Presidential Palace was attacked, but Makarios escaped and made his way to Paphos before leaving the island. The coup leaders installed Nikos Sampson as president. The new administration, however, failed to gain legitimacy either within Cyprus or internationally.
The coup shattered the island’s already fragile political balance. Citing its rights under the 1960 Treaty of Guarantee, Turkey launched a military operation on July 20. The UN Security Council adopted Resolution 353 the same day, calling for a ceasefire and an end to foreign military intervention. Talks in Geneva failed to produce a settlement, and a second Turkish military advance followed in August.
In Turkey, 42 years later, a faction within the Turkish Armed Forces attempted to overthrow the government on the night of July 15, 2016. Key sites in Ankara and Istanbul were targeted, including parliament, police facilities and other public buildings. The Bosphorus Bridge in Istanbul was blocked and military aircraft flew over Ankara.
The attempt was defeated by the response of security forces, military units that opposed the coup, political parties and civilians who took to the streets following President Recep Tayyip Erdoğan’s call. According to official figures, 251 people were killed and more than 2,000 were injured.
Ankara has said the Gülen movement, which it designates as FETÖ, was behind the attempt. The movement denied involvement. A state of emergency followed, bringing sweeping investigations, arrests and dismissals across the military, judiciary, police, public administration, education and media. The aftermath had a lasting impact on Turkey’s political system, state institutions and debate over civil liberties.
The 1974 coup in Cyprus collapsed within days, but it triggered a sequence of events that transformed the island’s political and territorial reality. The 2016 attempt in Turkey failed to achieve its immediate objective, yet it also opened a new chapter in the country’s political and institutional life.
Both anniversaries underline that the consequences of coups extend far beyond the day on which they unfold.
