Provisional representation of the former United Internal Revolutionary Organization

It threatened the autonomous Macedonia as state populated by different people as Bulgarians, Greeks, Serbs, Turks, Vlahs, etc.

In the parliamentary and local elections of 1919, the Temporary representation supported the candidates of the Bulgarian Communist Party (BCP).

Following the signing of the Treaty of Neuilly and the partition of Macedonia, the activity of the Temporary representation faded.

In 1920 it was dissolved and most from its members joined the Bulgarian Emigrant Communist Union as part of BCP.

They all were opposed to the restoration of IMARO as a Bulgarian nationalist organization under the name IMRO, headed by Todor Alexandrov.
