A coup d'état by the royalist leadership of the Greek Armed Forces takes place in Athens. It overthrows the government of Panagis Tsaldaris and establishes a regency under Georgios Kondylis, effectively ending the Second Hellenic Republic.
Panagis Tsaldaris (also Panagiotis Tsaldaris or Panayotis Tsaldaris; Greek: Παναγιώτης (Παναγής) Τσαλδάρης; 5 March 1868 – 17 May 1936) was a Greek politician and the 48th Prime Minister of Greece. He was a revered conservative politician and leader for many years (1922–1936) of the conservative People's Party in the period before World War II. He was the husband of Lina Tsaldari, a Greek suffragist, member of Parliament, and the Minister for Social Welfare.
