The Ukrainian Social Democratic Labour Party (Ukrainian: Украї́нська соціа́л-демократи́чна робітни́ча па́ртія, romanized: Ukrainska sotsial-demokratychna robitnycha partiia), also known as Esdeky^{[citation needed]} and SDPists^{[citation needed]}, was the leading party of the Ukrainian People's Republic. The party was reformed in 1905 at the Second Congress of the Revolutionary Ukrainian Party and was pursuing Marxism through the Social Democratic Party of Germany's Erfurt Program as well as national and cultural autonomy.^[2][1] Party leaders were Volodymyr Vynnychenko, Symon Petliura, Mykola Porsh, Dmytro Antonovych, Lev Yurkevych, Mykhailo Tkachenko, and Mykola Kovalsky.

The party identified its priority by resolving national matters and pushing its struggle for social liberalization of the working class to the secondary set.^[2] In the spring of 1905, in his polemics with Dmytro Antonovych that was covered on pages of the party publishing Pratsia, Mykola Porsh argued his opinion about the dependence of social and economic oppression from national.^[2] He insisted that overcoming social oppression foremost is necessary to solve the national issue.^[2] In Soviet propaganda, the party was identified as a petty bourgeoisie nationalistic party that was renamed as Ukrainian Social Democratic Labour Party to deceive people.^[3] Vladimir Lenin characterized the party as "representatives of the most low-grade, stupid and reactionary nationalism" who betray "interest not only democracy in general, but its own fatherland, Ukraine."^[3]
