The historical provinces (Finnish: historialliset maakunnat, singular historiallinen maakunta, Swedish: historiska landskap) of Finland are a legacy of the country's joint history with Sweden. The provinces ceased to be administrative entities in 1634 when they were superseded by the counties, a reform which remained in force in Finland until 1997. The provinces remain as a tradition, but have no administrative function today. The spread of Finnish language dialects approximately follows their borders. The first name in the parentheses is the Finnish name and the second is the Swedish one.
