The name appears in writing for the first time in 1211, as Kapos, and again in 1214 in the founding charter of the Premonstratensian house at Leles, a few kilometres to the south. The village belonged to those monks and stayed tied to them for centuries. Leles was also a place of authentication — a monastery licensed by the king to draw up, seal and store legal documents, which is the nearest thing the medieval kingdom had to a notary's office. Villages like this one have a written history at all only because such houses kept their paperwork.Meno sa v písomnostiach objavuje po prvý raz v roku 1211 v tvare Kapos a znova v roku 1214, v zakladacej listine premonštrátskeho prepoštstva v Lelese, ktoré leží pár kilometrov na juh. Dedina patrila leleským mníchom a zostala s nimi zviazaná po stáročia. Leles bol zároveň hodnoverné miesto — kláštor, ktorý mal od kráľa právo spisovať, overovať a uchovávať listiny, teda čosi ako vtedajší notársky úrad. Len vďaka takýmto kláštorom vieme o dedinách, ako je táto, vôbec niečo.
