At that year namely the Department of Political Science. was also differentiated as an independent division of UNWE. However, its foundations have been set up earlier in 1990 when the first academic plans of the speciality, first university courses and textbooks in Political science were elaborated. Since the inception of the Department and now on Head of the Department is Prof. Dr. Georgy Nedev Yankov.
