Bull of Gniezno

Ex commisso nobis, more commonly known as the Bull of Gniezno, was a papal bull issued on July 7, 1136 by Pope Innocent II. The bull split off the Bishopric of Gniezno from the Archbishop of Magdeburg. From a historical perspective, the bull is especially important as it contains the earliest written record of the Polish language. Slavic language scholar Aleksander Brückner called the document "złota bulla języka polskiego" ("the golden bull of the Polish language").
