Tha main aim of this paper is to determine the emergence of Comparative Public Administration (CPA), which is regarded as an important sub-discipline in Public Administration research, to examine the phases it has undergone, and to discuss the prominent thinkers in this field as well as their theories. Public Administration has developed as interdisciplinary in character in its two-hundred span of growth. It obviously owes this characteristic to its talents in comparative analysis. The comparative aspect of Public Administration is an inherent characteristic. The comparative method that have been used since the acceptance of Public Administration as a discipline in the modern sense has contributed to its intistutional aspects, and it has also made it easier to analyse by determining the similarities to and differences from its counterparts in the world. The analysis of Public Administration through comparative methods has become possible through CPA. In this regard, CPA is accepted as a sub-discipline, supporting research in Public Administration. CPA research, held methodologically for the first time following World War II, achieved maturation during Cold War era. The Cold War era, when theories of the discipline were mainly developed, is remembered as a period when regulations towards the welfare state were also made. Therefore, studies in CPA mainly followed a path of development in this direction. It can be seen that CPA studies during Cold War era were generally centered upon the administration structures of developed countries. Following the period, global management and liberalism came to the fore in line with New Public Administration Movement (NPAW). With the influence of globalisation, studies in the field expanded and became valid worldwide by attaining a comparative dimension. It is possible to handle research in CPA in its consequential development as “Early Period”, “Classical Period”, “Modern Period”, and “Contemporary”.
