In September 1939, during the German invasion of Poland, which started World War II, German troops massacred a group of Polish boy scouts from Złoty Potok in Tucznawa (see "Nazi crimes against the Polish nation"). The village was afterwards occupied by Germany until 1945. On September 11, 1944, Złoty Potok was the site of a battle between the Polish underground resistance and the occupying German forces. On September 17, 1944, during the Warsaw Uprising, the Germans carried out deportations of Varsovians from the Dulag 121 camp in Pruszków, where they were initially imprisoned, to Złoty Potok. Those Poles were mainly old people, ill people and women with children.
