The Institute follows ideas expressed by Czesław Miłosz and Jerzy Giedroyc and aims at construction of bridges between neighboring cultures and states that exists today in the territories many centuries ago occupied by the Grand Duchy of Lithuania and the Commonwealth of Both Nations. The institute collaborates with partners in neighboring countries in organizing seminars, conferences, public lectures and various types of schools, mostly in Lithuania, Poland and Belarus. One of the greatest projects is International Congress of Belarusian Sciences (www.icbs.lt) established in 2011 and annually held in Kaunas, usually in October. These Congresses became the most important international periodical academic events related to humanities and social sciences of Belarus. The Institute collaborates in publishing an English periodical journal Belarusian Political Science Review (Kaunas-Minsk). To add to this, in 2016 it starts another periodical in English – Annual of the Institute of Grand Duchy of Lithuania (Olsztyn-Kaunas).
