March 1911: Devolution comes into effect. There is widespread sectarian violence in both Ulster and Ireland. The Irish nationalists have split into three factions, the Federalists who want to work within the new system, the Nationalists who wish to continue pushing for full Dominion status and the Republicans who call for full independence. Despite forming a majority, the Nationalists and Republicans are unable to unite and split the vote, allowing the Federalists under William O'Brien to win a plurality and form a coalition government with the Southern Unionists.
March 1911: With devolution, violence breaks out both in Ulster and Ireland. Asquith attempts to remain aloof, allowing the local authorities to deal with the situation. But as violence continues calls for Westminster intervention grow louder. A meeting is held in Galway, which the Republicans boycott. Asquith firmly sticks to his position that it a matter for local government. Eventually it is agreed that troops will be deployed to restore order, but only at the request and under the direction of local government. The violence continues for several months before a tense calm is established. The compromise however, drives the Republicans further toward a hard line.

April 1916: Attempting to take advantage of British distraction due to the war, a group of Irish Republicans launch a rising in Dublin. The rising is rapidly suppressed and courts martial are arranged. Asquith intervenes, stating, as at Galway, it is a local matter, transferring the trials to civil courts under local law. This, along with the earlier handling of unrest will later become part of Commonwealth constitutional process as the Galway Doctrine. Few tried are found guilty and only three are sentenced to death. At Asquith's urging, those sentences are commuted to penal servitude. Irish public opinion begins to turn against radical nationalism as a result.
May 1916: The British launch an offensive in the Balkans in concert with the Serbs.
May 1916: The British Grand Fleet under Admiral George Callaghan clashes with the High Seas Fleet under Admiral Reinhard Scheer in the North Sea.

The rump Turkish state in Anatolia becomes a British client state.
November 1916: Since the start of the war the Entente have been purchasing massive quantities of war materials from the US, funded by loans secured against their gold reserves. This has resulted in an unprecedented economic boom in the US, the economy having grown by at least 10%. Having secured his second term as President, Woodrow Wilson becomes concerned by the seeming unending stalemate in the war. The Entente's gold reserves are finite and likely be exhausted within eighteen months to two years. An abrupt end to those orders would result in an equally unprecedented crash. Likewise an Entente defeat may result in default. He commissions a report on options in either event.

June 1917: By June it is clear the war is lost and civilian morale cracks. Riots and strikes breakout throughout Germany. In early July the High Seas Fleet mutinies. Revolutionary fervor spreads rapidly. The German government opens negotiations for an armistice and in early August the war comes to an end with Germany's defeat.
September 1917: While the abrupt end of Entente war orders has been cushioned by a major US military expansion program, the end of the war orders has triggered a major downturn in the US economy. Popular debate over the effects of the war orders becomes common.
October 1917: With the end of the war Asquith calls a new election and wins with a landslide. In Ireland, continued infighting between the Nationalists and Republicans, particularly over the 1916 rising, enables O'Brien's coalition to remain in power.

This assembly contains a mix of elected and appointed members.
