Answer and Explanation:
Tsotsi is set in 1956 in Sophia town, South Africa. Fugard wrote tsotsi in the early months of 1960 after the white community in Johannesburg had destroyed Sophia town. That was led to its destruction.
We can see the concept of identity crisis in the main character named Tsotsi, the anti-hero. He is “the one called Tsotsi,” which was his title or label rather than a name; that means “thug.” The name he got, did not give to him with love by his mother; neither does it connect him to his father’s family, tribe, or ancestors (which have more import to an African audience than a western one). So it can be seen clearly that there were a distance and a disconnection between Tsotsi and his family from the fact of his name.
His character is also seen to be damaged. He also does not have a recollection of his past, and he did not know the answers to any questions regarding his past. Therefore, he seems to be lost in a constant moment having no history or family to root him and put his actions into perspective.
So the main character shows the disillusionment and identity crisis.
