What were the outcomes and global effects of WW1?

Answer 1

-Some have argued that the Russian Revolution of 1917, and the ensuing civil war, would not have been possible without the war (WWI).
-Germany also had a sort of "civil" unrest of its own after the war. Germany's own Kaiser (German for "Caesar") WIlhelm was deposed in a coup, and later on Hitler would regard this as a betrayal of the German people, using this as his "justification" for waging war against the European powers. (Hitler felt that the new government was made up of Bolshevik communists; ironically it was Germany that had helped send Lenin- the father of Soviet communism- to Russia to foment the 1917 revolution).
-Economically, Germany was bankrupt because France, UK, Italy and the US (the winning side) forced it to make reparations in the billions of dollars. Germany was sunk into an economic depression in the 1920's. In 1923 France invaded Germany's productive Ruhr region in order to force Germany to pay. The Germans bitterly resented this and the Treaty of Versailles that was "forced" upon them. Germans felt that they never "lost" the war, but rather they were betrayed into signing a treaty that punished them. Once again this was "fuel" to the NAZI fire that was later used in justification of the German invasion of France and Europe.
-Much of Europe was also in economic ruin, but not as bad as Germany. England was forced to go off of the "gold standard" after the war. The gold standard was a monetary system whereby payments for trades of goods was backed up in gold. That is, any foreign currency could be exchanged for gold at a fixed price. Some economists say that the absence of the gold standard made prices of goods more unstable. This may have led to the price inflation of the 1920s. In Germany, for example, high inflation meant that you would need a barrel-full of DeutscheMarks just to pay for a loaf of bread. Inflation is always bad. But it is likely that the high inflation was also caused by economic problems in Germany, again also as a result of its loss in the war.
-The "Ottoman Empire", which was already on its last legs (many called it the"Old Man of Europe") was destroyed, laying the foundation for modern-day Turkey under their leader Ataturk (who is to many a tyrant- he killed millions of Armenians- but to Turks he is their "father").
-Many countries were formed in the wake of WWI, under President Woodrow Wilson's "self-determination" clause. Poland was "re-created", along with the Czech Republic and Hungary and the Yugoslavian Republics (formerly of the Austro-Hungarian Empire, which no longer existed after WWI). Hitler later used the principle of self-determination as an "excuse" to unite the German peope (there were Germans living in all these coutries), and to invade Czechoslovakia, Austria, Poland in order to extend the "living space" (lebensraum) of Germans.
-Militarily, WWI heped set the stage for different battlefield tactics and equipment. WWI was based on very slow, defensive trench warfare. As a result, many felt that the only way to win a war is to use rapid advances into enemy territory. Mechanized tank assault was pioneered both in Germany (under Hans Guderian) and in the United States (under Patton). Germany was able to advance through the Low Countries, France and Poland in 1939-1940 using Panzer tank Blitzkrieg (lightning war).
-The League of Nations was created out of WWI, the ideal of Wilson. However, the US Senate rejected the plan and the failure of the US to participate was a major blow to what might have been an important international institution. After WWII, the Allied powers formed the United Nations, which partly grew out of the failed League of Nations.
-The war helped, for the first time, bring America into a major international crisis. Unfortunately, America failed to take the lead in international affairs (as an example, it rejected the League of Nations), and it turned inward after the war, remaining largely protectionist. However, it did for the first time help provide economic support for an ally (initially the US was neutral, but after 1917 it supported Britain with millions of dollars in aid) as well as becoming militarily involved (the US had waited 3 years before entering the war). In some ways, the US repeated this in WWII: it would wait over 2 years to enter WWII (it entered in December 1941, the war had started September 1939). In a sense, you can regard WWI as a first test of American international power and involvement, with WWII being the highlight and pinnacle of that.
There's more, but this is a good sample I think.
