In the Middle Ages, in the area of today's Łazy were five settlements: Grabowa, Niegowonice, Wiesiolka, Wysoka and Ciagowice. Another village, which today is located within boundaries of Łazy, Chruszczobrod, belonged to the Duchy of Siewierz, which was incorporated into the Polish–Lithuanian Commonwealth in 1790. In the year 1386, King Wladyslaw Jagiello granted the villages of Niegowonice, Wiesiolka, Wysoka, Grabowa and Rokitno Szlacheckie to Wlodek of Charbinowice, the starosta of Lublin and czesnik of Kraków. Until 1795, Grabowa, Hutki Kanki and Niegowoniczki belonged to Lelow County, while Niegowonice, Wiesió∏ka,Wysoka, Ciagowice, Rokitno Szlacheckie and Turza were part of Kraków County. During the Swedish invasion of Poland, the area of today's Łazy witnessed heavy fighting and destruction. Stanislaw Warszycki, owner of the so-called Ogrodzieniec Properties, fought Swedish invaders. As a result, the Ogrodzieniec Castle was destroyed, together with numerous villages, such as Grabowa, with its fortified stronghold on the Lesser Poland – Silesian border.
