The Upper Savinja Valley is an area from which several early Slovenian administrative texts or records are already known, dating to before the mid-nineteenth century: a decree of the diocesan synod and a translation of a papal breve, both from Gornji Grad, and two oath forms for newly admitted dwellers of the market towns of Rečica ob Savinji and Mozirje. Through recent discoveries, new documents have surfaced, most notably tithe registers and two documents that are unique in the entire Slovenian area: the only probate inventory of a serf in Slovenian and the only last will of a serf drawn up by a priest. The article presents an overview of all hitherto discovered Slovenian administrative records from the Upper Savinja Valley, with a particular focus on those that have so far not been published and discussed.
