A royal banner was used as early as the reign of Boleslaus the Generous (r. 1076-1079). The earliest mention of a banner (, pronounced ) bearing the sign of an eagle is found in Wincenty Kadłubek's "Chronicle" which says that Duke Casimir the Just fought the Ruthenians in 1182 "under the sign of the victorious eagle". A seal of Duke Premislaus II from 1290 shows the ruler holding a banner emblazoned with a crowned eagle. Five years later, Premislaus was crowned King of Poland, and his crowned white eagle became the royal coat of arms of Poland. During the reign of King Ladislaus the Elbow-High (r. 1320–1333), the red cloth with the White Eagle was finally established as the Banner of the Kingdom of Poland (Polish: "chorągiew Królestwa Polskiego"). The orientation of the eagle on the banner varied; its head could point either upwards or towards the hoist. The actual rendering of the eagle changed with time according to new artistic styles.
