Public administration aims to understand how government can effectively achieve its proper functions. It studies the activities in public agencies and how they work to implement policies affecting society. The discipline has existed for centuries but was formalized in the late 19th century. Early thinkers aimed to make administration more competent by separating it from politics, applying business principles. Later, the field recognized the political nature of administration and sought to balance efficiency with other goals like accountability. It now sees its role as understanding and strengthening government institutions to better govern.
