The fall of Berlin wall was just a tipping point in the disintegration of USSR. It marked an important point in history with some scholars declaring it as end of communism. 

Following events are the precursor to the fall of Berlin wall or end of communism in East Germany : 

Sudden change in structure of economy proposed by Gorbachev, which created a shock to existing structure and notwithstanding change, it led to the eventual collapse of communist economies. 

Gorbachev’s policy of freedom of expression: This led to discontent being expressed freely, finally leading to a strong protest against communist economy. Example- A group called New Forum was formed in East Germany,which pressed for reforms in East Germany. Gorbachev’s policy of more power to states: This led to states like Hungary opening its borders to its western neighbours eventually leading to east Germans flocking in numbers to other western countries in search of jobs and livelihood. 

Above events combined led to the eventual fall of Berlin wall; when group of 5,00,000 protestors gathered and marched towards Berlin wall leading to its fall. Consequences of such fall has been phenomenal. East Germany having cheap labour and non-competitive industries lead its citizens to move in other economies in search of job and strengthening of industries in west Germany as they are more competitive. Moreover, generations which witnessed such fall continue to dominate the thinking and polity of Germany, in which more liberal western expresses multiculturalism whereas east Germans continue to be dominated by conservatives. But both Germany in regret of nazism that existed there, try to accommodate all cultures and peoples in its economy and society.
