The time period leading up to World War I was the age of Imperialism, a time when many countries in Western Europe were building up their empires throughout the world. They would often times get into disagreements amongst themselves over who was to control certain areas of the world. The countries were jealous, suspicious and did not trust each other. There was also a huge influence from the Industrial Revolution, which introduced new technologies and weapons used in the war. World War One a great example of, advancements, challenge,disputes with other nations, distrust, and social changes, with the introduction of inventions such as, aircrafts and the tanks, and many more. Alliances played a role in spreading the WWl because of a dispute with Serbia and Austria-Hungary which ended up pulling in others because of the pacts all of the countries had signed. There were two big alliances created, the Triple Entente and the Triple Alliance. The Triple Alliance was created by Germany, Austria-Hungary, and Italy. The Triple Entente, was signed by Great Britain, France, and Russia. These alliances helped to keep Europe divided. With these alliances, the balance of power in Europe were able to be maintained and easily handled. The sparks of war were caused, by rivals in the Balkans and an interest in the independence against the Austria-Hungary Empire. The war came to place because of the assassination of the Austrian archduke, Franz Ferdinand and his wife. Tensions began to come up such as, nationalism, imperialism, and militarism which created distrust, because of the assassination, Austria Hungary sent an ultimatum to Serbia to avoid war. Which they partially agreed to. Others were sided with Serbia, such as France and Russia. Serbia turned to its ally Russia, which terrorized Germany and created a war. All due to the assassination of the Archduke and his wife, this created huge strife between two sides, creating others to side with them in fear of facing other battles alone. Nations found themselves dragged into the war by pre-existing alliances, and knowledge of these alliances played a key role in the decisions taken by major players in the war. The major consequences of World War I included the distrust of people from the other countries. This eventually led to uncertainty and a major difficulty to make balanced agreements. New military strategies were formed because of the destruction of their weapons. They were also experiencing a long time stalemate which eventually led to the trench warfare which was to avoid bloodshed and being blown up by enemies. They dug deep holes called trenches, which they stayed in for many days, even weeks. Trenches were in very poor condition, leading to some militants to become extremely sick or develop serious disease. It was hard for them to gather resources to restock in the war, which was hard for them to defeat their enemies on the opposing side. This led to new military strategies which were used to try to defeat and break the stalemate between both sides. New weapons were made such as the machine gun and the long-range artillery gun. Other various weapons were used, but they weren’t as significant as the two powerful guns. Poisonous gases were also used to suffocate the opposing side so they could die painfully and slowly, but eventually that backfired because the side using the deadly weapon were affected as well because debris or wind would fly back onto the people who were launching the item towards their enemies. Technologies such as U-boats was also known as Submarines, convoys, tanks, and airplanes, were all used to defeat opposing sides and to stop the stalemate. Tanks were used to cross “no man’s land” without being killed. Before the tanks came to place, anyone who tried to cross no man’s land would automatically be killed, it was like committing suicide. Germany was one of the countries that felt taken very taken advantage of. Since they were defeated in the war, they had to pay for all the the reparations, they also had give away land and also take all of the blame. This caused many of the German people great dissatisfaction. In addition, the Greatest outcome of the war was that the Empires were broken up into smaller states. It also helped women get voting rights, so in a way the social outcomes of the war were positive. Many consequences and many hardships for both the nations and the people were very excruciating because so many things were happening all at once, new wars were started between nations, people were being treated unfairly, harsh punishments, etc. The impact of the Great War, created political, economic, and social changes.The Russian Revolution was the series of revolutions in Russia , which destroyed the Tsarist autocracy and led them to create the Soviet Union. In the first revolution in February, the Czar were overthrown and replaced with the Provisional government. In the second revolution in October the Provisional Government was removed and replaced with a Bolshevik which took part of the communist group. Socialists set up soviets which were councils of workers and soldiers. Lenin, lead the Bolsheviks and adapted towards many different ideas. They then eventually went to war with Russia, and was called the Bolshevik Revolution. After the revolution, Russia signed a treaty called the Treaty of Brest-Litovsk, which gave up half of their territory and population. The Allies had ordered for the Germans to sign a treaty, known as The Treaty of Versailles. One of the outcomes was that Germany had lost a lot of its population and of its territory, including one of the leaders to surrender back to France after leading for half a century under German rule.They had to take full blame for causing the war, and they had to also have to pay for huge reparations which were caused during the war. The results of the Great War was that the Germans eventually claimed peace and sought for an armistice. World War One, or the “Great War”, was one of the greatest examples of advancements, strategic challenge, with the introduction of inventions such as the aircraft and the tank the battlefield transformed from attrition as the scene in the early years of the war to decide by the end of the war. This is true because, there were many technological improvements such as new sources of military equipment and weapons, many challenges such as revolutions, stalemate, bloodshed etc. The outcome of the war left many global consequences besides the death and bloodshed of the militants, there was much more.
