The present article traces the development of the concept of social justice through different philosophical traditions. The notion and philosophy of 'Justice' is the core of socio-legal and political streams and ethics. The idea of justice is applied not just to individual engagements but to broader aspects such as public policies and laws of the land. Justice is often used in the context of 'righteousness' and as a 'virtue'. Still, it is not easy to define and completely clarify the concept of justice. We can analyse it by employing specific terms, which acquaint us with the best possible understanding of justice. A single definition would not suffice to fulfil our aim of the study. Therefore, in this essay, the author delineates how philosophers and thinkers have theorised 'Justice' throughout ancient, medieval and modern times.
