Märkische Heide is a municipality in the district of Dahme-Spreewald in Brandenburg in Germany.
On 26 October 2003, the municipality of Märkische Heide was formed by merging 17 municipalities. These were Alt-Schadow, Biebersdorf, Dollgen, Dürrenhofe, Glietz, Gröditsch, Groß Leine, Groß Leuthen, Hohenbrück-Neu Schadow, Klein Leine, Krugau, Kuschkow, Leibchel, Plattkow, Pretschen, Schuhle-Wiese and Wittmannsdorf-Bückchen.
From 1815 to 1947, the constituent localities of Märkische Heide were part of the Prussian Province of Brandenburg, from 1947 to 1952 of the State of Brandenburg, from 1952 to 1990 partially (Alt-Schadow, Biebersdorf, Dollgen, Dürrenhofe, Glietz, Gröditsch, Groß Leine, Groß Leuthen, Hohenbrück-Neu Schadow, Klein Leine, Krugau, Kuschkow, Leibchel, Pretschen, Schuhle-Wiese and Wittmannsdorf-Bückchen) of the Bezirk Cottbus and partially (Plattkow) of the Bezirk Frankfurt of East Germany. Since 1990, they have again been part of Brandenburg, since 2003 united as the municipality of Märkische Heide.
"Märkische Heide", also known as "Brandenburglied", is the title of a well-known German song, whose text mainly praises the beauty of the local countryside.[2] The Chilean military song Mi fusil y yo adopted its melody.[3]
