 In the autumn of 1918, as World War I drew to a close, Cluj became a centre of revolutionary activity, headed by Amos Frâncu. On 28 October 1918, Frâncu made an appeal for the organisation of the "union of all Romanians". Thirty-nine delegates were elected from Cluj to attend the proclamation of the union of Transylvania with the Kingdom of Romania in Alba-Iulia on 1 December 1918, later acknowledged internationally by the Treaty of Trianon. The interwar years saw the new authorities embark on a "Romanianisation" campaign: a Capitoline Wolf statue donated by Rome was set up in 1921; in 1932 a plaque written by historian Nicolae Iorga was placed on Matthias Corvinus's statue, emphasising his Romanian paternal ancestry; and construction of an imposing Orthodox cathedral began, in a city where only about a tenth of the inhabitants belonged to the Orthodox state church. This endeavour had only mixed results: by 1939, Hungarians still dominated local economic (and to a certain extent) cultural life: for instance, Cluj had five Hungarian daily newspapers and just one in Romanian.
