On 13 June 1789, the Third Estate had arrived at a resolution to examine and settle the powers of the three orders. They invited the clergy and nobles to work with them on this endeavor. On 17 June, with the failure of efforts to reconcile the three estates, the Communes completed their own process of verification and almost immediately voted a measure far more radical: they declared themselves redefined as the National Assembly, an assembly not of the estates, but of the people. They invited the other orders to join them but made it clear that they intended to conduct the nation 's affairs with or without them. As their numbers exceeded the combined numbers of the other estates, they could dominate any combined assembly.
