The Estates-General reached a deadlock in its deliberations by 6 May.[2]:xv The representatives of the Third Estate attempted to make the whole body more effective and so met separately from 11 May as the Communes. On 12 June, the Communes invited the other Estates to join them: some members of the First Estate did so the following day. On 17 June 1789, the Communes approved the motion made by Sieyès that declared themselves the National Assembly[3] by a vote of 490 to 90.
