The First World War that occurred in August 1914 changed soon. It is often said that the war is "a locomotive of history" - that is the reason for it being moved. Of course, the First World War brought about major changes in the UK, especially the social and economic aspects. The First World War brought about a major economic change. The UK industry has changed significantly by mobilizing millions of soldiers and converting to war production more than ever. From a positive perspective, the economy shows new production capacity.
World War II had a dramatic impact on America in the 1920s (and of course, the majority of the world's 20th century). On the one hand, it has raised the United States to the world's superpower, and has led the economic prosperity for ten years. On the other hand, that terrible death toll and seemingly meaningless eternity eliminated the idea of war of aristocracy and glory. I will easily check what happened. After the assassination of Austria - Hungarian heir Archzke Franz Ferdinand in 1914, the Austrian-Hungarian Empire and its allies Germany declared war against Russia. Russian allies France and the UK have been dispatched to protect Russia. Following whatever alliance they did in the past, smaller European powers were forced to fight again. In the first three years, the United States maintained neutrality, but instead gained the benefit of war by selling goods to both sides of the conflict. However, in 1917, the United States worried about the alliance between Germany and Mexico and fell into battle.
In August 1914, Russia entered World War I and backed Serbs and their French and British allies. In the military, the Russian empire can not be compared with modern industrialized Germany. Russia's participation in the war is disastrous: Russia's casualties exceed the number of casualties in any other country, food and fuel shortages rapidly plague this vast country. Lenin realized the vacuum of leadership that bothered Russia and decided to grab power. He secretly organized factory workers, farmers, soldiers and crew members into a red guard - a volunteer army. On 7th and 8th November 1917, Red Guard occupied the temporary government building with a bloodless coup.
