After years of fighting World War I, European countries that had suffered heavy losses were ready for peace, but domestic economic and political upheavals brought trouble to Britain, Ireland, and France throughout the 1920s. This paper traces the historical events taking place in these countries after the war. Great Britain experienced economic problems and labor strikes as well as conflicts within its colonies. Ireland fought for Independence from Great Britain, while dissent among the Irish erupted into a civil war. France attempted to rebuild after the war’s destruction but experienced widespread poverty after the franc’s value dropped, coped with labor strikes, and faced internal political struggles after the French Communist Party formed.
