Following the lost anti-British War, in 1838 the first English Revolution took place. King Philip was killed. The Revolutionaries declared the British republic. The Royal family under his successor George I fled to New Albion (OTL New Zealand). The pope went with them (including the highest clerics, who soon decided to move with the pope to bigger Antipodia, however).
The british monarchists weren't happy, and in 1839, admiral Carleton swore to retake Britain for the monarchy. The admiral collected the British navy in the Pacific, went to the North Sea, prepared for a strike against London. After having sailed to Swedish Helgoland, admiral Carleton stroke in 1840 when the "divine wind" blew the right way. The completely surprised republican government had the workers of London armed to defend them.
Their strategy backfired: 1841, the Second English revolution. After the defeat of the admiral, Socialist leader and former bartender Charles Pounder took power in London, declared the "People's State of England".
The Second English Civil War took place during 1841-44. With the help of the rail workers, the Socialists gained the upper hand against the monarchists and moderated republicans; many of the latter fled to Canada, of the former to New Albion.
The land of the crown and the nobles was divided between the small peasants and land workers; in the cities, the workers took control of the factories. The Bank of England and other government offices were taken over by the Socialist leadership.
