1414–1434 A provostry, walls, and the Hussites anywayPrepoštstvo, hradby a husiti napriek tomu

In 1414 Duke Stibor brought Augustinian canons to Nové Mesto and founded a provostry — a church with its own body of clergy and its own estates, endowed with the villages of Pobedim and Bašovce. He planned a great Gothic rebuilding of the parish church and died before it was finished. His son Stibor II, as captain of the Váh valley, was ordered by the king to wall the town against the Hussites; the walls went up, and the Hussites attacked anyway, in 1431 and 1432. Stibor II completed his father's church and died in 1434, after which the town passed through his daughter's husband, Pavol Bánfi, to the Bánfi family.Roku 1414 povolal vojvoda Stibor do Nového Mesta augustiniánov a založil tu prepoštstvo — kostol s vlastným zborom duchovných a vlastnými majetkami, obdarený dedinami Pobedim a Bašovce. Plánoval veľkú gotickú prestavbu farského kostola a zomrel skôr, ako ju stihol dokončiť. Jeho syn Stibor II. dostal ako kapitán Považia od kráľa príkaz opevniť mesto proti husitom; hradby vyrástli a husiti aj tak zaútočili, v rokoch 1431 a 1432. Stibor II. otcov kostol dostaval a roku 1434 zomrel; mesto potom prešlo cez manžela jeho dcéry, Pavla Bánfiho, na rod Bánfiovcov.
