History 
According to some historians, the dragon was adapted in Polish heraldry from the Matter of Britain. It most likely was introduced as a coat of arms of the Czersk Land thanks to Magnus, son of Harold Godwinson, king of England, that was a komes in Masovia in the 12th century. The oldest known appearance of the Piast Dragon is the seal of duke Trojden I, ruler of the Duchy of Warsaw, that was used after 1311. Later, it was used in the coat of arms of the Duchy of Czersk. According to Jan Długosz, Piast Dragon had appeared on the banner used by duke Janusz I of Warsaw during the Battle of Grunwald in 1410. The dragon has also been present in the coat of arms of the town of Nowy Żmigród. It was introduced in the area in 14th century by Yuri II Boleslav, ruler of the Kingdom of Galicia–Volhynia, who was the son of Trojden I. Currently, the dragon is present in the coat of arms of several counties of Masovian Voivodeship, Poland, that are: Garwolin (since 2002), Grójec (since 2000), Ostrów (since 2002), Otwock, Pruszków, and Warsaw West. It is also used in the coat of arms of municipilaties of Lesznowola and Nowy Żmigród. In folklore
