In the early Middle Ages, Nur was a trade center, with a Roman Catholic parish established here probably in the 12th century.

After annexation of Mazovia into Poland, and creation of Masovian Voivodeship, the Land of Nur consisted of three counties: Kamieniec Mazowiecki, Ostrów Mazowiecka, and Nur, which also was the seat of a starosta, Sejmik, and land court for the three counties.

Boundaries of the Land of Nur remained unchanged for over 400 years, until the Partitions of Poland.

The town had 263 houses, a number of craftsmen and merchants, a brewery, a folwark, eight watermills and four fairs a year.

In 1648, during the Khmelnytsky Uprising, the Land of Nur equipped 100 cavalrymen, sending them south to fight the enemy.

The town continued its decline: in 1853, the church was dismantled, and replaced with a wooden chapel.
