The most well-known 'shift' in relations between the United Kingdom and her colonies occurred in 1931 with the passage of the
Statute of Westminster by the British parliament. This act formally ratified the idea that Britain was giving her colonies further freedom to enact their own laws and statutes; and making Acts of Parliament no longer immediately apply to those independent Dominions.
No Act of Parliament of the United Kingdom passed after the commencement of this Act shall extend, or be deemed to extend, to a Dominion as part of the law of that Dominion, unless it is expressly declared in that Act that that Dominion has requested, and consented to, the enactment thereof.
No law and no provision of any law made after the commencement of this Act by the Parliament of a Dominion shall be void or inoperative on the ground that it is repugnant to the Law of England, or to the provisions of any existing or future Act of Parliament of the United Kingdom, or to any order, rule or regulation made under any such Act, and the powers of the Parliament of a Dominion shall include the power to repeal or amend any such Act, order, rule or regulation in so far as the same is part of the law of the Dominion.
Upon ratification of the act, it went into effect for
Canada, Australia, New Zealand, Newfoundland, and South Africa; the five major British dominions that existed at the time of the act's ratification. Many Irish nationalists agitated against the Statute, as it meant that Ireland, which had been treated as a second-class asset of the British Empire for generations, was less free than the colonies that their people had helped raise up from agrarian villages into bustling cities.
The Statute of Westminster set the stage for the ratification of the
Home Rule Act of 1933, two years later. During this period, the Belloc government was beginning to debate the merits of certain states being given a measure of freedom from Britain's grasp, in exchange for oaths of loyalty and affirmations that the Commonwealth would be left sundered by the years.
The first of these states was
Nigeria. One of Britain's most advanced 'black' colonies, Nigeria was, in many eyes, seen as a prime example of British 'uplifting'. It was decided that as an experiment to see how African self-governing could fare, Nigeria would be made into a Dominion in much the same vein as Canada. A shocking decision on Britain's part, but with an empire overextending and the economy beginning to run out of the steam it had gained in the 1920s, Belloc's government felt justified in giving one of Britain's most 'model' African colonies some measure of self-determination. This flamed some resentment in their other colonies which were not given self-determination.
The first post-'Dominion' elections held called for the election of the 120 seats of the
Nigerian parliament. In the election, 105 seats were won by the
National Party, with the remaining 15 seats won by the
Party for African Brotherhood; a nationalist party that wanted independence from Britain completely, with the abolition of the Governor-General's position as the 'regent' for King George V.
This was followed by the cession of the
Bechuanaland colony to the Union of South Africa--a move that had been delayed consistently in the last 23 years, but had finally been decided on. This lessened the British burden in Africa and allowed them to redistribute assets and resources to some of their new protectorates in the Middle East.
And finally, old Ireland, Britain's first colony and long-time 'red-headed stepchild', was allowed to organize to Home Rule. Elections were held in each of the 'counties' of Ireland to determine which would go with the new dominion, and which would remain directly integrated into the United Kingdom. The counties of
Antrim, Down, Armagh, Tyrone, Fermanagh, Londonderry and Donegal voted to remain within the United Kingdom, while the remainder of Ireland from Monaghan to Cork, voted to join the Dominion of Ireland.
Within the United Kingdom, the loss of the Irish seats meant that the Irish Parliamentary Party was now effectively defunct as an entity, and
Arthur Griffith invested the effort to set up his party as the natural leader of the new Irish dominion.
After the partition, the United Kingdom parliament shed several dozen seats to make up the difference; bringing the total number of seats in Parliament to 619. The next election in 1934, would definitely cause a shift in politics; While the former Sinn Fein remnants certainly had support amongst many people in County Donegal, there was a significant push for 'normalcy', and many Donegal voters would swing for National Mobilization, or even Labour in some instances. Irish independence damaged the standing of Prime Minister Belloc, but despite this, many people supported Irish home rule entirely on the premise that it was time for Britain to let Ireland breathe just a little bit so Britain could focus on other things.
