Groningen (Gronings: Grönnen; West Frisian: Grinslân) is the northeasternmost province of the Netherlands. In the east it borders the German state of Niedersachsen (districts of Leer and Emsland), in the south Drenthe, in the west Friesland and in the north the Wadden Sea. The capital of the province is the city of Groningen.--------Originally a part of Frisia, Groningen became a part of the Frankish Empire around 785. Charlemagne assigned the Christianization of this new possession to Ludger. In the 11th century, the city of Groningen was a village in Drenthe that belonged to the Bishopric of Utrecht, while most of the province was in the diocese of Münster. During the Middle Ages, central control was remote, and the city of Groningen acted as a city state, exerting a dominating influence on the surrounding Ommelanden. Around 1500, Maximilian I, Holy Roman Emperor gave Groningen and Friesland to Albert, Duke of Saxony, who could however not establish permanent control.
