Regents of Mazovia and Kuyavia

Today Mazovia and Kuyavia compose the central part of Poland (the capital Warsaw is located in Mazovia). But in medieval time was this region often ruled without much regard to the Polish central power. A pagan uprising c. 1037 meant that Mazovia in practise was independent for a whole decade. The province's time as self-governing principality began however first with the division of Poland between the heirs of the late prince in 1138. At that time was four hereditary Polish principalities created, which formally lay under the sovereignty of the prince of Krakow. But this overlordship was only theoretical and during the following 400 years was there one or more Mazovian principalities who effectively was outside the Krakow princes' and later the Polish kings' control (they even recognised Bohemia's overlordship instead of Poland's 1329-1351). Just like what had happened in 1138 was Mazovia partitioned several times between sons to former princes. Kuyavia became a principality of its own already in 1186 and its prince restored the Polish kingdom in the year 1320. Mazovia however continued to exist as a self-governing part of Poland until 1526 when the branch of the House of Piast that had ruled Mazovia became extinct, whereupon the province was returned to the Polish king.
