Compare the rise of Communism in the Soviet Union to the rise of fascism in Italy and Germany.

I think that a primary connection between both rises in
governments was the basic element that people felt that the existing governments were
either ineffective or detrimental to the general welfare.  Either the people felt this
or were manipulated to feel this way through skilled individuals who advanced the rise
of a new form of government in contrast to the Status Quo.  The presence of overwhelming
economic conditions and a lack of clear vision on the part of the Status Quo helped both
rise.

In the case of the Soviet Union, the disenchantment
caused by poverty and a failed entry into the First World War helped set the stage for
the Czar's overthrow and the ushering in of a Communist government.  The belief that
Russia was ready to forego an autocratic and royal government and embrace a new system
where workers worked for a workers' state was what motivated the drive for
Communism.

Similar in economic disenchantment and political
muddle, charismatic leaders like Mussolini and Hitler were able to mold public opinion
and associate themselves with nationalism.  Accordingly, these individuals were able to
present themselves as the penultimate solution to their nation's problems, and embracing
fascism that supported their own ascendancy to power allowed them to be able to become
the face of their nations.  In both contexts, the rise of new governments arose from the
case being made that the preceding political orders failed to address the needs of "the
people" and that a new vision could do so.
