Zenne in the context of "Landgraviate of Brabant"

Naast (Walloon: Nåsse) is a village of Wallonia and a district of the municipality of Soignies, located in the province of Hainaut, Belgium, known by the wellspring of the river Zenne.

Its population continued to increase throughout the nineteenth century. In 1972 a city was built to address the housing crisis but also to maintain a young population in Naast who tended to emigrate.

The Duke of Brabant (Dutch: hertog van Brabant, French: duc de Brabant) was the ruler of the Duchy of Brabant since 1183/1184. The title was created by the Holy Roman Emperor Frederick Barbarossa in favor of Henry I of the House of Reginar, son of Godfrey III of Leuven (who was duke of Lower Lorraine at that time). The Duchy of Brabant was a feudal elevation of the existing (since 1085/1086) title of landgrave of Brabant. This was an Imperial fief which was assigned to Count Henry III of Leuven shortly after the death of the preceding count of Brabant, Herman II of Lotharingia (born 20 September 1085). Although the corresponding county was quite small (limited to the territory between the rivers Senne and Dender) its name was applied to the entire country under control of the dukes from the 13th century on. In 1190, after the death of Godfrey III, Henry I also became duke of Lotharingia. Formerly Lower Lotharingia, this title was now practically without territorial authority, but was borne by the later dukes of Brabant as an honorific title.

In 1288, the dukes of Brabant became also dukes of Limburg. The title fell to the dukes of Burgundy in 1430. Later on, it followed with the Burgundian inheritance until the French Revolution, although the northern part of the territory of Brabant was actually governed by the United Provinces during the 17th and 18th centuries (see Generality Lands).

Silva Carbonaria, the "charcoal forest", was the dense old-growth forest of beech and oak that formed a natural boundary during the Late Iron Age through Roman times into the Early Middle Ages across what is now western Wallonia. The Silva Carbonaria was a vast forest that stretched from the rivers Zenne and the Dijle in the north to the Sambre in the south. Its northern outliers reached the then marshy site of modern Brussels.

Further to the southeast, the higher elevation and deep river valleys were covered by the even less penetrable ancient Arduenna Silva, the deeply folded Ardennes, which are still partly forested to this day. To the east, the forested zone was possibly considered to extend to the Rhine. It was there in Cologne in 388 CE that the magistri militum praesentalis Nannienus and Quintinus began a counter-attack against a Frankish incursion from across the Rhine, which was fought in the Silva Carbonaria.
