The state's ambiguous status ended in 1949, when the Republic of Ireland Act stripped the King of his role in external relations and declared that the state may be described as the "Republic of Ireland". The decision to do so was sudden and unilateral. However, it did not result in greatly strained relations between Ireland and the United Kingdom. The question of the head of the Irish state from 1936 to 1949 was largely a matter of symbolism and had little practical significance. The UK response was to legislate that it would not grant Northern Ireland to the Irish state without the consent of the Parliament of Northern Ireland (which was unlikely to happen in unionist-majority Northern Ireland).
