Raja is a term commonly used in South Asia, particularly in India and Nepal, to refer to a king or a ruler. Historically, rajas governed various regions and were often part of a feudal system. They held significant power and were responsible for maintaining law and order, collecting taxes, and protecting their subjects. The title is also associated with nobility and royal lineage. In modern contexts, the term "raja" can be used more broadly to denote someone with authority or leadership qualities. It is also a popular name in many cultures and can be found in various forms of art, literature, and folklore, often symbolizing strength and wisdom.
