The Serbian Emperor Stefan Uroš IV Dušan (reigned 1331-1355) donated beekeepers with beehives near Krupište to the Monastery Hagios Panteleemon on the Holy Mount Athos on 12 June 1349 (konь krupištь). The current village of Ularci, which is located 2 km to the North-East of Krupište, probably emerged from this settlement of beekeepers. Stefan Dušan confirmed the Monastery of Sveti Petar Koriški as metochion of the Monastery of Hilandar on the sabor (state assembly) held at Krupište on 17 May 1355 (zьbor na Krupištihь; na zboru na Krupištihь). The respective charters were composed by the Serbian Logothet Gjurg in Ovče Pole. Stefan Dušan issued a third charter in favour of the Monastery of Hilandar on the same sabor at Krupište on 2 July 1355 (zborь na Krupištihь). The charter was written by the same Logothet in Ovče Pole. Also in 1355 a charter for the Church of Sveti Nikola in Dobrušta (in Kosovo) was issued by Stefan Dušan, when he was in Krupište (stoještu... vь Krupištehь). The village of Krupište is mentioned in the charter of the Serbian Despot Jovan Dragaš and his brother Konstantin Dragaš for the Monastery Hagios Panteleemon on the Holy Mount Athos, which they issued after 1376/77 (I u Krupištehь selo Ulijari i selište Butkovcь). The village of Krupište is attested in the Lesnovski pomenik (Krupišta; 16th century). It is also registered in the Defter for the Sanjak Köstendil from 1519, 1550 and from the years 1570 to 1572 as Kurpšta.
