The author brings up an interesting issue which in the recent years has aroused intense interest of historians. Majorov tries to prove that military expedition of Prince Roman the Great in 1205 (that ended up with his death in the battle of Zawichost) was only an episode it the fight between Staufs and Welfs and was directed against Saxony. Majorov states that more important source than Jan Dlugosz Chronicle is the oeuvre of Alberic of Trois-Fontaines. The crucial thing, which is presented by the author, is the great scale of foreign policy of Prince Roman the Great. Polish historians see the conduct and attitudes of prince from the angle of Kadlubek's chronicle and consequently perceive him as a ruler dependent on both: Kazimierz Sprawiedliwy and Leszek Bialy. Yet he was a prominent political figure. It should be emphasized that the author used various primary sources and multilingual literature (i.e. Russian, German, Ukrainian, Polish).
