Yolanda became the wife of Bolesław the Pious, Duke of Greater Poland. Béla's first son, Stephen was born in 1239. He succeeded his father. Béla's youngest daughter, Margaret was born during the Mongol invasion in 1242. Dedicated to God by her parents at birth, she spent her life in humility in the Monastery of the Blessed Virgin on Rabbits' Island and died as a Dominican nun. The King's youngest (namesake) son, Béla was born between around 1243 and 1250. The Greater Legend of Saint Elisabeth of Hungary (Béla's sister) described Béla's family as a company of saints. It wrote that the "blessed royal family of the Hungarians is adorned with resplendent pearls that irradiate all the earth". In fact, the Holy See sanctioned the veneration of three daughters of Béla and his wife: Kunigunda was beatified in 1690, Yolanda in 1827; and Margaret was canonized in 1943. A fourth daughter, Constance also became subject to a local cult in Lemberg (Lviv, Ukraine), according to the Legend of her sister, Kunigunda. The following family tree presents Béla's offspring, and some of his relatives mentioned in the article. Legacy Bryan Cartledge writes that Béla "reorganised the structure of government, re-established the rule of law, repopulated a devastated countryside, encouraged the growth of towns, created the new royal town of Buda and revived the commercial life of the country" during his over three-decade-long reign. Béla's posthumous epithet—the "second founder of the state" ()—shows that posterity attributed to him Hungary's survival of the Mongol invasion. On the other hand, the Illuminated Chronicle notes that Béla "was a man of peace, but in the conduct of armies and battles the least fortunate" when narrating Béla's defeat in the Battle of Kressenbrunn.
