At the onset, there was a desire to remain unified, and the competing groups wished to maintain a common country. The Internal Macedonian Revolutionary Organisation collaborated with the members of the "CUP", and Greeks and Bulgarians joined under the second biggest party, the "LU". The Bulgarian federalist wing welcomed the revolution, and they later joined mainstream politics as the People's Federative Party (Bulgarian Section). The former centralists of the IMRO formed the Bulgarian Constitutional Clubs, and, like the PFP, they participated in 1908 Ottoman general election.
