excuse to intervene militarily in the internal affairs of Russia.", "After her death, Boles\u0142aw married to a German noblewoman, Salomea of Berg, which in some way was the cause of changes in Polish foreign policy: in the second half of his rule, the Prince sought to restore diplomatic relations with his western neighbor.", "His last, and perhaps the most momentous act, was his will and testament known as \"The Succession Statute\" in which he divided the country among his sons, leading to almost 200 years of feudal fragmentation of the Polish Kingdom.", "Boles\u0142aw III Wrymouth
