Birth of Weimar Republic after First world war and how Germany suffered it's consequences

Germany, a powerful empire in the early years of the twentieth century,  fought the First World War (1914-1918) alongside the Austrian empire  and against the Allies (England, France and Russia). All joined the war enthusiastically hoping to gain from a quick victory. Little did they realise that the war would stretch on, eventually draining Europe of all its resources. Germany made initial gains by occupying France and Belgium. However the Allies, strengthened by the US entry in 1917, won , defeating Germany and the Central Powers in November 1918.The defeat of Imperial Germany and the abdication of the emperor gave an opportunity to parliamentary parties to recast German polity. A National Assembly met at Weimar and established a democratic constitution with a federal structure. Deputies were now elected tothe German Parliament or Reichstag, on the basis of equal and universal votes cast by all adults including women.This republic, however, was not received well by its own people largely because of the terms it was forced to accept after Germany's defeat at the end of the First  World War. The peace treaty at Versailles with the  Allies was a harsh and humiliating  peace. 

Germany lost its :

1.overseas colonies

2.a tenth of its population

3.13 per cent of its territories

4.75 per cent of  its iron and 26 per  cent of  its coal to  France,  Poland, Denmark and Lithuania.

 The  Allied Powers  demilitarised Germany  to weaken its power.  The  War Guilt Clause  held Germany  responsible  for the war  and  damages  the Allied countries suffered.  Germany was forced to  pay compensation amounting to £6 billion.  

The  Allied armies also occupied the resource-rich  Rhineland for  much  of  the 1920s.  Many Germans held the new  Weimar Republic responsible for  not only  the defeat in the war  but the  disgrace at  Versailles.
