The article follows on an earlier publication by the author devoted to the urban development of Małopolska under Boleslaus the Modest (Krasnowolski, 2004–2005, pp. 36–37, 38–39). At the same time, it expands the subject discussed by the author in another work several years ago (Krasnowolski, 2004). The period in question was actually a quarter of a century from 1279 to 1306. The first of these dates marks the start of the reign of Leszek the Black (Leszek Czarny), successor to Boleslaus the Modest (Bolesław Wstydliwy), and the latter — capture of Kraków by Ladislaus the Elbow–High (Władysława Łokietka), efficiently competing with the rulers of Bohemia and exploiting the death of Wenceslaus III of Bohemia (Wyrozumski, 1992, pp. 200–201). Urban development from the time can be considered continuation of the urban development policy of Boleslaus the Modest, yet at a lower dynamic, due to political instability.
