After the death of Henry II the Pious his realm was divided between various Piast dukes. In the second half of the 13th century, Henry II's grandson, Henryk IV Probus of Silesia, made an attempt to gain the Polish crown, but he died in 1290 before realizing his goal. Duke Przemysł II of Greater Poland united two of the original provinces and was crowned in 1295, but was murdered in 1296. According to his will, Greater Poland was to be inherited by Duke Henryk III głogowski, (a Silesian duke of Głogów) who also aspired to unite Poland and even claimed the title Duke of Poland. However, most nobles supported another candidate from the Kuyavian line of Piasts, Duke Władysław I the Elbow-high. Władysław eventually won the struggle because of his broader support. In the meantime, King Wenceslaus II of Bohemia decided to extend his rule and was crowned as King of Poland in 1300. The next half-century was rife with wars between Władysław (later his son Casimir III the Great) and a coalition of Bohemians, Brandenburgers and Teutonic Knights trying to divide Poland. During this time, all Silesian dukes accepted Władysław's claims for sovereignty over other Piasts. After acquiring papal consent for his coronation, all nine dukes of Silesia declared twice (in 1319 before and in 1320 after the coronation) that their realms lay inside the borders of the Polish Kingdom.
