Danish minority of Southern Schleswig

The Danish ethnic minority in Southern Schleswig, Germany, has existed by this name since 1920, when the Schleswig Plebiscite split German-ruled Schleswig into two parts: Northern Schleswig with a Danish majority and a German minority was united with Denmark, while Southern Schleswig remained a part of Germany and had a German majority and Danish and Frisian minority populations. Their historic roots go back to the beginning of Danish settlement after the emigration of the Angles.
