Provisional government is an emergency or interim government set up when no government has yet been established, or when a political void has been created by the collapse of an existing government. There is no specific way a provisional government must be organized or run. By its very name — provisional — it is understood to be a temporary solution until a permanent system of governance can be instituted.
In the case of Red River Settlement, there were actually two provisional governments during the Resistance of 1869–1870, the first giving rise to the second.
