What lead to the rise and fall of the Soviet Union?

(1) The rise: deteriorating economic and political conditions in the Russian economy resulted in social unrest which allowed the communist to capitalize on the situation, promising equal rights to people of lower status.

(2) The fall: A rapidly failing post World War II economy and weakened military, along with a series of forced social and political reforms like perestroika and glasnost, played major roles in the fall of the mighty Red Bear.

the group i'm selecting: greeks.
