The Congress of Oppressed Nationalities of the Austro-Hungarian Empire was held towards the end of the World War I in Rome, Kingdom of Italy, between 8 and 10 April 1918.{{cite book |author1=Mary Heimann |date=2011 |title=Czechoslovakia: the State That Failed |pages=33 |publisher=Yale University Press |isbn=978-0-300-17242-3 }} The event, attended by Czechoslovak, Polish, Italian, Yugoslav and Romanian delegation from Austria-Hungary, followed the publication of the Wilson's 14 points and represented the beginning of the real support to the independence movements and the dissolution of Austria-Hungary.{{cite web |author=Petr Matějček |title=Kongres utlačovaných národů rakousko-uherských, v dubnu roku 1918 v Římě |url=http://www.vhu.cz/kongres-utlacovanych-narodu-rakousko-uherskych-v-dubnu-roku-1918-v-rime/ |date=4 April 2021 |publisher=Military History Institute Prague |access-date=1 October 2022}}{{cite journal |author1=Andrea Carteny |date=2010 |title=After the Wilson's 14 Points: the Oppressed Nationalities at the Congress of Rome (April 1918) |journal=Историјски записи |volume= |issue=3 |pages=123–135 |url=https://www.ceeol.com/search/article-detail?id=28583 }} Ukrainian or Rusyn delegations were not invited to participate in the Congress due to objections raised by Polish representatives. The decision to host the event was made after prime ministers of Italy Vittorio Emanuele Orlando and Nikola Pašić of the Kingdom of Serbia became concerned with earlier statement of David Lloyd George that dissolution of the Austria-Hungary is not one of the war aims of his alliance and decided to prioritise self-determination before future border demarcation on the Adriatic Sea.{{cite book |author1=Zoran Bajin |date=2018 |chapter=Никола Пашић и Италија уочи стварања југословенске државе (1917–1918) |trans-chapter=Nikola Pašić and Italy Ahead of the Formation of the Yugoslav State (1917–1918) |title=Дан вредан века – 1. децембар 1918. |trans-title=The Day Worthy of the Century – 1 December 1918 |pages=33–48 |publisher= Museum of Yugoslavia |url= }} The event rejected Austrophilist proposals on continued existence of the monarchy as a guarantor against violent and exclusive nationalism in the region and instead framed the war as a conflict between democracy and autocracy.{{cite web |url=https://ww1.habsburger.net/de/kapitel/das-selbstbestimmungsrecht-der-voelker-die-patentloesung-fuer-ethnische-konflikte |date=n.d. |title=Das "Selbstbestimmungsrecht der Völker" – Die Patentlösung für ethnische Konflikte? |publisher=Schloß Schönbrunn Kultur- und Betriebsges.m.b.H. }}

Alongside representatives from affected nationalities, all Entente powers and the United States sent their ambassadors and the Congress concluded that all nationalities fully or partially subjected to Austria-Hungary have a right of full independence.{{cite book |author1=Marina Cattaruzza |date=n.d. |chapter=Great Britain, Italy, the "oppressed nationalities," and the dissolution of Austria-Hungary in the First World War |title=n.t. |pages=1–19 |publisher= |url=http://italogramma.elte.hu/?dl_name=Marina_Cattaruzza_The_Dissolution_of_Austria-Hungary_in_World_War_One_2.pdf }} Ceremonial choice was made by the Prime minister Vittorio Emanuele Orlando when he decided to receive the delegation of the future neighboring Yugoslav state before any other delegation at the Congress. Czechoslovak representation was led by Edvard Beneš and Milan Rastislav Štefánik with all Slovak and Czech delegates being a part of the Czechoslovak National Council's delegation.{{cite web |url=https://zurnal.pravda.sk/neznama-historia/clanok/467181-jar-1918-nadej-prichadzala-z-rima/ |date=24 April 2018 |title=Jar 1918: nádej prichádzala z Ríma |author=Vladimír Jancura |publisher=Pravda (Slovakia) }} Participant agreed to lay aside any dispute among themselves which would help Central Powers war efforts and which may negatively affect Allied public opinion.{{cite web |url=https://history.state.gov/historicaldocuments/frus1918Supp01v01/d801 |date=4 April 1918 |title=The Ambassador in Italy ( Page) to the Secretary of State |publisher=Office of the Historian }}

Important precondition for the Italian agreement on hosting the event was reached during the meetings held on 14 and 18 December 1917 at the home of Wickham Steed, where the Yugoslav Committee agreed in principle to accept the subsequent Torre-Trumbić agreement (7 March 1918) on principles of border demarcation between Italy and future Yugoslav state.{{cite web |last1=Carteny |first1=Andrea |title=All Against One: The Congress of Oppressed Nationalities of Austria-Hungary (1918) |url=https://www.academia.edu/5653336 |website=academia.edu |date=January 2010 |access-date=3 October 2020}} On 29 May 1918 United States Department of State expressed US government's strong interest in the work of the Congress and honest sympathies for Czechoslovak and Yugoslav national objectives.{{cite journal |author1=Livija Kardum |date=1991 |title=Geneza jugoslavenske ideje i pokreta tijekom prvog svjetskog rata |trans-title=The Genesis of the Yugoslav Idea and the Movement During World War I |journal=Croatian Political Science Review |volume=28 |issue=2 |pages=65–88 |url=https://hrcak.srce.hr/113311 }}
