The people, or population, are one of the most important factors in the state, and the government's inability to defend the people's fulfilment and rights, as well as to conduct geopolitical propaganda, are the fundamental causes of today's issues and crises. The world's perceptions of politics and war changed radically during the twentieth century. Without a doubt, the twentieth century has seen a shift from conventional to urban warfare, as well as other factors, resulting in natural and forced migration, immigration, displacements, and refugee movements as people strive to protect themselves and future generations from atrocities.
At present, Refugee Law is primarily governed by the 1951 Convention its 1967 Protocol, and UNHCR guidelines but as seen by numerous examples from throughout the world, the existence of a framework is not sufficient. There is a significant disconnect between theory and practice. To share the same viewpoint, the research paper is structured into several sections with the main objective to analyse the legal instruments parallel with the case of Rohingyas. The paper aims to understand the refugee’s law and its theory, the legal instruments and response to it and the practice of refugee’s treatment associating with the Rohingya’s issue. With the view that a comprehensive analysis can be formulated to understand the disparity between the theory law and the practice law.
