Republicans waged an armed campaign for a British withdrawal and not for an Assembly in the North and cross-Border bodies, the Republican Sinn Fein ardfheis heard.
About 50 people attended a low-key political debate on Saturday, a smaller number than in previous years. Some 140 delegates heard Mr Ruairi O Bradaigh's speech yesterday.
A former Provisional IRA prisoner from Belfast, Mr Brendan McClenaghan, was among those present. Rejecting the Belfast Agreement, Ms Mary Ward from Donegal said: "A British withdrawal is the only thing people fought and died for. People do not fight for seats in a partitioned assembly, they fight for liberty."
Ms Sarah Murphy from south Armagh said party members "are pledged to defend Pearse's republic using whatever means necessary, and we intend to do so".
The party's vice-president, Mr Des Long, predicted the Provisional IRA and Sinn Fein would compromise further. They had dropped their policy of abstentionism from the Dail, were now at Stormont, and "sooner or later the surrender of arms will happen, too".
Any future alliances with the 32 County Sovereignty Movement or the Irish Republican Socialist Party, the INLA's political wing, were firmly rejected in one motion, which was unanimously passed.
Another resolution passed called on "all other groups to drop the name of republicanism as they have discredited the meaning of the name and are not fit to call themselves by it".
One resolution rejected the Patten report on the RUC and any attempts by the Provisional IRA to "police the peace".
Referring to the salary of Assembly members, Mr Joe O'Neill from Donegal said: "Judas received 30 pieces of silver. These boys are getting £30,000."
Mr O Bradaigh said "pro-British media" insisted on describing as republican the Provisional IRA and Sinn Fein - which he claimed had abandoned republicanism - while labelling those who continued to adhere to the ideology as dissidents.
Mr O'Neill said: "We in Republican Sinn Fein are dissident from nothing. We are what we were in the 1920s, in 1969, in 1986. It's the continuity of the thing. We uphold republican principles from the time of Wolfe Tone."
