Since 1742, Dukla belonged to Jerzy August Mniszech, who in 1750 married Maria Amalia von Bruhl (the daughter of Heinrich von Bruhl). Together with his wife, Mniszech turned the town into a cultural center of the region, with a theatre, orchestra and a Masonic lodge. The Mniszechs competed with the Czartoryski family, which tried to turn their private town (Puławy in northern Lesser Poland) into the cultural capital of Poland (see also Izabela Czartoryska). In 1768 Jerzy Mniszech wrote a constitution for Dukla, in which he stated that all children were subject to education, regardless of their creed.
