In 1920 most of the European countries had democratic governments established.
Thus in the post-World War I there was the success of democracy almost in every European state. But soon after there was severe constraints on democracy.
The causes were as follows:
(1) Economic crisis in Germany in early 1920 and the Great Depression of 1929 totally destabilized the European economy.
ADVERTISEMENTS:
(2) Some states of Europe in the period, immediately after World War 1, suffered racial instability as a result of conflicting ethnic groups.
(3) Defects that existed in some of the new constitutions also helped the emergence of authoritarian rule.
(4) The democracy in the postwar period was severely weakened by the absence of any really popular statesman during the inter-War years.
