Until the conclusion of the Anglo-Irish Treaty in 1921 it was the mission of Dáil Éireann to create a parallel system of government in Ireland that would gain the allegiance of the public and eventually supplant the British state. Some success was achieved in this goal. For example, the Dáil was able to persuade many Irish people to boycott the British judicial system and instead seek justice in a network of Dáil Courts. Nonetheless, the Irish Republic was not quite a true "de facto" state and received no support among the Unionist majority in North-East Ireland.
