This paper tries to examine the role and position of parliamentary diplomacy in today's international relations with a brief review of the history of diplomacy, its evolution in the span of time, and the formation of new types of diplomacy. The paper also seeks to answer questions about the role of parliaments in today's international relations as well as the position of parliamentary diplomacy within the framework of regional and international cooperation. However, it is generally opined that parliamentary diplomacy is not competing with traditional state-oriented diplomacy as parallel diplomacy. Rather, by emphasizing the continuation of the Westphalian model of nation-states in today's international system, it serves as a complementary tool to state diplomacy in favor of securing the national interests of countries.
