How did the war start? The First World War began on June 18, 1914 and assassinated Ambassador Franz Ferdinand and his wife, the nephew of the Austrian Emperor who was visiting the Austrian-Holland Empire of Sarajevo, Bosnia and Herzegovina. The assassination of the Serbian nationalists led to the plan that the Austrian Hungarian Empire will fight against Serbia. Austria and Hungary did not respond quickly to this incident, but secured a treaty with Germany. This allowed Serbia to reach the treaty with Russia.
The direct cause of the First World War was the assassination of the Austrian Grand Duke Franz Ferdinand and his pregnant wife Sophie. The Austrian Grand Duke Franz Ferdinand was the nephew of Emperor Franz Joseph and was the successor to the throne of Austria and Hungary. The assassination was planned by a Serbian terrorist organization, Mafia, a man who shot Franz Ferdinand and his wife, Bosnian revolutionary named Gabriello.
There was a major event mainly leading to the beginning of the First World War. This case was the current nephew of the emperor of Austria, hence the assassination of the Grand Duke Franz Ferdinand, the heir to the throne. Dagong and his wife were shot in the middle of a parade of Mafia member Gavrilo Princip. Mafia is an organization whose purpose is to unite all Serbs under one government. As a result of the assassination, on July 28 the Austrian Hungarian Empire announced its opposition to Serbia. Thanks to the alliance regime, the countries were pulled one by one. There are many reasons for the beginning of the Second World War. Some of these reasons are the depression of the Great Depression, the rise of nationalism, and the emergence of leaders like Adolf Hitler and Benito Mussolini. The main reason for the outbreak of war in Europe is that Poland invaded Germany on September 1, 1939.
World War I started with the assassination of the Duke Franz Ferdinand of Austria. The Austrian-Hungarian Empire declared a war with Russia, Germany announced the war against Russia and France. Then Germany invaded Belgium, Britain declared war against Germany. The Germans submerged a private marine vessel called Lusitania. It offended the USA, and the Germans promised not to attack the passenger ships without warning. On April 6, 1917, the US officially declared a war against Germany. After a lot of people lost their lives, Germany collapsed and Adolf Hitler was imprisoned.
