What events preceded the outbreak of the First World War?

Of course, it is generally accepted that the assassination of the Erz-Duke of Austria marked the beginning of the First World War. But this was just a formality. If you dig deeper and delve into the facts of that time, we can conclude that the flourishing of such empires as the German, Ottoman and Russian preceded the First World War. Western capitalists could not put up with the power of these empires, they suffered colossal losses, since they could not control profits from industries from these territories. These empires occupied colossal territories with huge reserves of natural resources. It was necessary to separate them somehow. It was necessary to start a war.
