World War I was a war that could have been prevented. If all the forces of Europe are only acting to comply with one another, we can save the lives of many people and no death will happen. Mainly between the Austrian-Hungarian Empire and Germany against Serbia, Russia, France and the UK, the reason is that some people have sacrificed many lives for selfish governments to expand the empire . The main perpetrator of the First World War was the Austrian-Hungarian Empire. The reason for the war in the Austrian-Hungarian empire is that they last sent to Serbia, which will lead to the declaration of the war and the battle of all other countries.
But from another point of view of analyzing war, Germany alone is the cause of the outbreak of the First World War. From the point of view of the Balkans, the Austrian-Hungarian Empire and Serbia will be the root of the problem as they are involved in the Sarajevo crisis that triggered the war. Firstly, the Balkan war was two wars between Serbia, Montenegro, Greece, Romania, Turkey and Bulgaria between 1912 and 1913. The countries involved in the war battled the remaining European territory of the Ottoman Empire. The war seriously hampered the European alliance. As a result of the Second Balkan War, the scale of Serbia doubled and it became a shocking military force. Do you want Serbia to unite all the Slavic people and create "wonderful Serbia?" Like Zionism, this is passionate Panslavism.
After the Austrian-Hungarian Empire declared a war with Serbia, the conflict of alliances began to play a role. Tied to the agreement of Serbia, Russia announced the mobilization of its vast army for its defense. Germany, which has signed an alliance with the Austrian-Hungarian Empire through the Convention, believes that the mobilization of the Russian army was a threat on August 1, 1914 and declared war with Russia. After Germany and France signed a clear enemy, France and Russia signed a treaty and fought against Germany on August 3. Britain who is more relaxed with France has been morally enforced to defend France; they declared a war against Germans on 4 August. US President Woodrow Wilson announced the absolute neutrality of the United States, but since Germany restricts ships in other countries, it threatens US commercial transport seriously. So Americans were forced to fight Germany.
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.
