The design of the pennant is based directly on the pre-war Banner of the Republic of Poland which used to be part of presidential insignia.
The pennant of the president is defined in the Ordinance of the Minister of National Defense on the Use of Insignia of the Armed Forces of January 26, 1996 with subsequent amendments.
Although its design changed with time, it was always a heraldic banner, i.e. one based directly on the national coat of arms: a crowned White Eagle in a red field.
