Hamm is a provincial city in Westphalia, some 30 kilometers northeast of Dortmund, in the county of Mark. When the ruling house of Mark became extinct in 1609, it´s territories, including the city Hamm, went to Brandenburg-Prussia in 1624 after a dispute with Pfalz-Neuburg.
Mamm struck a local copper coinage from 1609 to 1749.
The coat of arms has been in use in its present form for about 750 years. It shows the markish chessboard ("märkischen Schachbalken") in red and silver on a golden field. Originally it was the founders' coat of arms, i. e. the Counts of Mark. The chessboard and the colours are often displayed in the coats of arms of further towns founded by that family line. Similarly, the colours of the city are red and white.
The name Ham means "corner" in the old Low German dialect spoken at that time. In the old times the name thom Hamme would be used, which evolved slowly into its modern form Hamm. The name derives from the description of the Hamm's location in the corner of the Lippe river and the narrow Ahse affluent, where it was founded on Ash Wednesday in March 1226 by Count Adolf I of the Mark.
