The creation and granting of counties and baronies in Finland began with the coronation of King Eric XIV in 1561 and continued through Great Reductions in the latter half of the 17th century.
King John III is responsible for both the first granted barony, the barony of Viikki, to Klaus Eriksson Fleming in 1570 and the first granted county, the county of Raseborg, to baron Sten Eriksson of Grevsnes' widow and heirs in 1571.
Much later, in Gustav II Adolf's reign, the same baron Erik was granted permission to use his own late father-in-law's (Klas Fleming's) barony of Wik as his and his wife's baronial title.
King Charles IX granted just one barony, the barony of Nynäs to Abraham Leijonhufvud, and Gustav II Adolf granted the county of Pärnu (in modern Estonia) to Frans Bernhard von Thurn, the barony of Kimito to Axel Oxenstierna and the barony of Tuutarhovi (in Ingria, now Tuutari) to Juhana Skytte.
Queen Christina I of Sweden was a most profligate donator, having created more than half of the ever existed baronies, during 1647-54: After Christina's reign, fiefs were soon to be confiscated, but yet Charles X Gustav created P. Wuertz baron of Örneholma that had fallen extinct.
