Kraszna county (Hungarian: Kraszna vármegye) is a former administrative county (Latin: [[Comitatus (Kingdom of Hungary)|comitatus]]) of the Kingdom of Hungary along the river Kraszna; its territory is now in north-western Romania. Its capital cities were Krasznavár (today in German: Krassmarkt, Romanian; Moldavian; Moldovan: Crasna), Valkóvár (Romanian; Moldavian; Moldovan: Cetatea Valcău) and Szilágysomlyó (German: Schomlenmarkt, Romanian; Moldavian; Moldovan: Șimleu Silvaniei).
The county was established in the 12th century within the Árpád Kingdom of Hungary.
In the 16th century Hungary was divided: from 11 November 1526 Kraszna was part of the Eastern Hungarian Kingdom, which became an Ottoman vassal in 1529; the western part of Hungary became part of the Habsburg Monarchy. On 16 August 1570, by the Treaty of Speyer, the Eastern Hungarian Kingdom became the Principality of Transylvania. Kraszna was one of the counties of the Latin: [[Partium]] which were ruled by Transylvania but legally considered part of Hungary.
Kraszna remained under Transylvanian rule until the Treaty of Karlowitz in 26 January 1699, whereby Transylvania, the Latin: Partium and most of Ottoman-controlled Hungary passed to the Habsburg Monarchy. Transylvania formally became a crown land in the 1711 Treaty of Szatmár which ended Rákóczi's War of Independence, but the status of the Latin: Partium remained ambiguous until 1732, when Kraszna definitively became part of Transylvania, along with, and the rump Zaránd County.
Between 1851 and 1860 the counties of Transylvania were abolished and replaced with German: [[Kreis (Habsburg monarchy)|Kreise]]; the territory of Kraszna County became part of the German: [[Cluj-Napoca|Klausenburger]] Kreis[1] until 1854, then German: Kreis [[Șimleu Silvaniei|Szilágy-Somlyó]].[2] The counties were restored in 1860.
On 29 May 1867 the Austro-Hungarian Compromise, which transformed the Austrian Empire into Austria-Hungary, saw the abolishment of Transylvania; its counties fell directly under Hungarian rule, becoming part of "Transleithania".
In 1876 the Hungarian counties were restructured and the territory of Kraszna County passed to the new Szilágy County.
