Kosturi, son of Albanian patriot and activist Jovan Cico Kosturi was born in Korçë in south-eastern Albania, back then Ottoman Empire, on 15 May 1873. Kosturi studied US and German history in Boston, MA, where he resided for several years. He became an American citizen. After his return home, being a polyglot and intellectual and having a patriotic family background, Kosturi joined the Albanian irredentist circles in the Manastir Vilayet. He was vice-chairman of the Secret Committee for the Liberation of Albania based in Bitola. He was a member and bookkeeper of the "Dituria" society founded in Korçë, and led by Orhan Pojani. After a visit to Bucharest, Kosturi told Albanians in Korçë that the main concern of Dituria was to improve the Albanian boys school in the town through student attainment of higher grades, selecting better teachers and introducing new subjects. In 1909, he participated as representative of "Dituria" in the Congress of Elbasan, where it was decided the opening of Shkolla Normale e Elbasanit. In 1912, his name appears again as a member of the short-lived society "Shoqëria shkollore". He was a strong supporter of the Albanian Orthodox Church autocephaly, and the first Albanian church opened in Durrës in 1913. During the First World War he resided in Albania where he led his own cheta from 1914 to 1918. He continued the political involvement in the new Albanian state. In 1919, Kosturi was a delegate in the Congress of Durrës, following with hist participation in the Congress of Lushnje. In 1920, he was elected Minister of Posts and Telegraphs. During the institutional crisis of 1921 in Albania, he served shortly as Prime Minister of Albania, replacing the short-lived government of Hasan Prishtina. Meanwhile, Kosturi had built reputation and financial stability as a successful merchant. In 1922, he signed the order for expulsion of Greek Bishop Iakovos from Korçë. He was a supporter of Fan Noli during the June Revolution of 1924. Kosturi was Deputy Prime Minister in Noli's government of 1924. After the suppression of June Revolution and rise in power of Ahmet Zogu, he went in exile and joined Noli's KONARE. Kosturi returned into Albanian political life on 1 October 1943, as a representative of Korçë region, and the same year was elected to lead the Commission for Mandate Verification, later Chairman of Constitutional Assembly of Albania on 25 October 1943. As a chairman, he declared as "void" all laws and legal act approved during 7 April 1939 and September 1943. Thus the "Personal unification" between Albania and Italy came to an end. He declared the official Albanian neutrality in World War II. He was shot on 5 November 1943 in Durrës, right after leaving his home. The responsible party was the local Communist Guerrilla Unit. The action was carried out by a young communist, Kolë Laku. It is still unknown why Kosturi was pinpointed by the communists. When the future Albanian Prime MinisterRexhep Mitrovica was voted in the Parliament, he proposed the Assembly to declare National day of mourning. Kolë Laku became well known when he was arrested on 24 February 1944, and would be hanged. For his merits in Albanian political life and his state-forming and organizative contributions to Albania, Mihal Zallari directed that the square in front of the former Assembly of Albania building be renamed from "Costanzo Ciano" to "Idhomene Kosturi". With the rise of Communism in Albania, his patriotic, political, and financial contribution would get annihilated. He would be referred as "traitor" or even "Gestapo agent".
