How Did Archduke Franz Ferdinand's Involvement In World War I

World War I is one of the largest and most violent events in human history. Its reach across the globe is much larger than many seem to think. Most literature along with public knowledge seems to focus on the western front when overall there was 8 major fronts during the First World War. The war’s clash of old tactics with new war machines meant many unneeded casualties. I say unneeded because many think the war was useless, and it proved nothing.

It is common knowledge that the spark that led to World War I was due to the assassination of Archduke Franz Ferdinand, but, does this event carry much weight in the timeline

My research revolves around the German perspective because of their huge involvement in World War I, even though they were not one of the initial nations in the conflict. The German reason for involvement has a backstory that reaches back decades and is full of jealousy and grudges across the royal families. The war most likely would not have been worldwide, and most likely would have been contained in Serbia and Austria Hungary if it weren't for the tense family relationships. I want to research why the squabble of two small nations became a world war. Though, this is one of many theories that is hotly debated among circles. There is virtually no viewpoint on its origins that cannot be supported from a selection of the available sources. And, this helps in turn to explain why the World War I origins literature has assumed such vast dimensions that no single historian, even with every necessary language, could hope to read it in one lifetime. Years ago an overview of Causes of World War I found that there were over 25,000 books and articles. They bring up theories ranging from a bad apple state like Germany, allegedly. Or faults in the system. This has kept the debate going since the end of the First World War. The research of theories can be extremely confusing, disorienting,
