How did a new
political space emerge?

The thesis traces the development of Lithuanian statehood and the expansion of its influence in the lands of Rus’. It connects political history with the mechanisms used to build and sustain power.

The central narrative covers the 13th and 14th centuries. Its background reaches back to the earliest mentions of Lithuania, while the final chapter continues to the reign of Vytautas. The study draws on historical scholarship and chronicles.
