In the latter part of nineteenth century, German thinker, Karl Marx put forward ‘Class Theory’ in his book ‘Das Kapital’.
According to him:
1. History i not about abstract ideas but living people. The fullillment of basic needs of people depends on the nature of prevalent means of production and the ownership.
2. All the different strata of the society do not get equal access to these means of production which causes the division of the society into classes. It results into class struggle.
3. The class which owns means of production $ economically exploits the rest of the classes. Human history, according to him, is the history of class struggle.
