The author of the research essay "How Did Karl Marx Explain Change in Human Society?" starts with a short introduction to this interesting topic. He begins with that Karl Marx is one of the greatest social thinkers and philosophers, who has influenced the future generations through his remarkable works and magnificent theoretical structure on class conflict. “Marxism has brought into existence in many of the socialist countries, whether fortunately or not, conditions of political oppressions and cultural impoverishments which represent in the eyes of many observers, a notable decline from a level of civilisation previously attained.” (Bottomore, 1975: p 38) The concept Marxism has been derived after the theories of Marx and Frederick Engels, where both the socialist thinkers consider class struggle as an inevitable social phenomenon in order to erase inequalities from human societies that are the outcome of Capitalistic economic system, which has widened the gulf between the haves and haves-not. Marx’s wonderful publication “The Communist Manifesto” is the most celebrated pamphlet in the history of the Socialist Movement that aims to define causes and consequences of social change in societies. Several social theories that emphasise social conflict, according to Ryanzanskaya, (1971) have roots in the ideas of Karl Marx. There is nothing permanent except change. it is an essential law of nature, not an exception or uneven thing. The same is the case with social and cultural changes.
