Różan
Różan stands on the Narew in northern Mazovia. A settlement grew below its stronghold, enjoying the support of the Masovian dukes, particularly Janusz I of Warsaw. It received town rights in 1378 and became the centre of the Land of Różan. The river connected the town with other settlements along the Narew, while the ducal stronghold anchored its place in the administration of Mazovia. Like the surrounding duchy, Różan eventually came under the authority of the Polish Crown.
