The concept of corporate social responsibility (CSR) has a long and varied history associated with the evolution of the concept and the definition of corporate social responsibility (CSR). on the other hand, although it is possible to see CSR fingerprints around the world, formal writings have been most evident in the united states, where a considerable number of publications have accumulated. this movement of corporate social responsibility began in the 1950s in the United States before it appeared in Europe in the 1990s. indeed, from the appearance of the book «Social Responsibilities of the Businessman (SRB) » of Howard R. Bowen who is identified as the founding father of the concept of corporate social responsibility, different definitions have been written in relation to this concept, and to this day no definition seems to have the consent around the world to achieve universal thinking. our objective through this document is to highlight the conceptual evolution of corporate social responsibility and we also present the various most widely used definitions that are exhaustive in nature.
