Ommen (Dutch pronunciation: [ˈɔmə(n)] ) is a municipality and a Hanseatic city in the eastern Netherlands. It is located in the Vecht valley of the Salland region in Overijssel. Historical records first name Ommen in the early 12th century and it was officially founded as a city in 1248. The municipality had a population of 18,295 in 2021 and covers an area of 182.01 km2 (70.27 sq mi).
Besides the city of Ommen (population: 8,710) and the town of Lemele (population: 570), the municipality consists of the following hamlets and villages:
The first inhabitants of the area around Ommen were probably semi-nomadic hunter-gatherers. Flint from the Mesolithic period found in between Ommen and Mariënberg indicates the presence of humans around 9,000 BCE, but there seems to have been hardly any cultivation or permanent settlement during this period.
The Vecht (sometimes called the Overijsselse Vecht, to avoid confusion with its namesake in Utrecht) and Regge rivers determined the first settlements in the area that is now the municipality of Ommen. Most of the Salland region was marshy but the higher banks along the Vecht and Regge provided fertile soil for agriculture. Moreover, good roads were rare, so for trade, transport and travel the rivers provided a vital infrastructure. The first sporadic agricultural settlements in Salland therefore arose along the riverbanks of the Vecht and the Regge around 5,000 BCE. Indeed, all early population centres in the current municipality of Ommen were originally built on riverbanks — with the exception of the town of Lemele, which was situated on the lower slopes of the Lemelerberg, free from flooding by the Regge.
The location of Ommen itself proved particularly suitable for settlement — not only because of the fertile river soil and the higher ground of the river dune (even today the church square is visibly higher than the streets to its east and south), but also because of the ford in the Vecht facilitating trade routes between the Frisian north and Twente to the south. Archeological discoveries indicate that the first settlement in Ommen itself emerged during the 8th century CE, and by the end of the 11th century a veritable town had developed — among the first in Overijssel. The first permanent settlers in Ommen were mixed crop-livestock farmers who also engaged in river trade and innkeeping. Most of these first settlers were probably of Saxon origin, though the Salians who dominated the banks of the IJssel also influenced the region economically, politically and religiously. The first houses in Ommen were hutkommen: wooden houses of which the ground floor was typically around half a meter below the ground. A church was built at the heart of Ommen around 1150 and was soon after replaced by a stone church, indicating further growth of the settlement. Written records first mention Ommen as de Vmme in 1133 and as Ummen in 1227.
This gradual growth, however, did not mean Ommen could also dominate the surrounding area politically, as there were many other powers in the land. Above all, the Prince-Bishop of Utrecht, who had obtained dominion over all of Oversticht from Henry II, Holy Roman Emperor, in 1010, repeatedly attempted to increase and centralise his authority over the towns and estates of Salland. The burghers of nearby cities — especially Zwolle — were also known to interfere in the region. More locally, farming communities in the eastern Netherlands organised themselves into markes (autonomous areas) where a buurschap (rule by neighbours) formed a unique kind of grassroots local government. Last but not least, havezates (or castles) arose in the area surrounding Ommen — especially at strategic points such as the banks of the Vecht (the Arendshorst on the northern bank and Beerze on the southern bank), the banks of the Regge (most notably at Eerde) or both banks ('t Laer) — from which robber barons dominated the surrounding area and could levy tolls on river commerce in defiance of the authority of the bishop. These robber barons and the buurschappen formed a check on the influence of Ommen on the surrounding region — yet it was ironically due to one such robber baron that Ommen grew to become an outright city.
On 25 August 1248, Ommen received city rights and fortification rights from Otto III, the Prince-Bishop of Utrecht, after the town was pillaged by local robber baron Rudolf of Coevorden and his militia of freemen in both 1215 and in the aftermath of the Battle of Ane of 1227. Ommen's location at the confluence of two rivers at the heart of the region made it the bishop's strategic and logistic basis in the defence of his domain Oversticht against the rebellious Drents. Ommen thus became the 4th-oldest officially recognised city in Overijssel, after Deventer (956 A.D.), Zwolle and Rijssen.
A wall was soon erected around Ommen, including three gates: the Vechtpoort or Voorbruggenpoort (on the bank of the Vecht), the Varsenerpoort (on the western wall for traffic with Varsen) and the Arriërpoort (on the northern wall for traffic with Arriën). Even to this day, the two bells in the church's belltower, named Maria and Salvator and cast in 1517 by Hendrick de Tremonia of Dordrecht, are rung every evening at nine o'clock. These so-called Ave-Maria peals form a custom which traces its origin to the tradition of ringing the bell at the closing of the gates. Ommen never received a moat, even though it was permitted one.
Ommen soon became a regional port and market for agricultural products. Due to this commercial growth and strategic commercial position, Ommen eventually joined the Hanseatic League as a smaller port, so most of its trade was not directly with the Baltic Sea region, but with fellow Hanseatic cities Zwolle, Kampen, Zutphen and especially Deventer, of which it was a subsidiary city. A toll bridge across the Vecht (first built in 1492) further increased its wealth and commercial importance, even though the toll bridge across the Vecht was destroyed by ice floes three times through the centuries. The toll levy was usually auctioned off to private tax collectors, who resided in the toll house (built in 1531) next to the bridge. A bridge toll would be levied until 1925.
For centuries during the Middle Ages, the Estates of Oversticht, a diet or feudal parliament representing the quarters of Salland, Twenthe and Vollenhove (and until 1527 also Drenthe) and the cities of Zwolle, Deventer and Kampen, convened just outside the city of Ommen at Nieuwebrug (or New Bridge), named after the bridge over the Regge on the road between Ommen and Hellendoorn. Following a feud between Kampen and Zwolle in 1519, however, a gathering of the Estates was attacked by citizens of neighbouring Zwolle, who abducted three noblemen and pillaged nearby Eerde castle. During the years that followed, conflict escalated in Overijssel.
In 1522, citizens of Zwolle attacked and pillaged Ommen with the aid of Duke Charles of Guelders who thus conquered the city from Utrecht. Only the church and women's home de Heilige Geest (the Holy Spirit) survived the pillage and fire.
Ommen remained part of Guelders until 1528, when emperor Charles V inherited authority over the entire Duchy of Guelders, including Overijssel. A new city hall was built in 1531 in between the church and the Vrijthof square. The city was pillaged again in 1568 by Spanish troops under the 'Iron' Duke of Alba, fighting for Charles's successor, Philip II of Spain. This time, the pillage was not as devastating: Ommen's church, city hall and several other main buildings were spared. In 1581, the Estates of Overijssel convened outside Ommen to depose Philip and proclaim the independence of the Netherlands.
Though a 'Golden Age' for the young Dutch Republic, the 17th century proved rather devastating for Ommen. A great fire in 1624 inflicted serious damage on the church, of which only the foundations and a few walls remained. To control traffic and to prevent military invasions from the north, the fortification of Ommerschans was constructed. In 1672, one of the most severe fires in Ommen's history raged through the entire city, destroying everything but the church. In that same year, the aptly named 'Rampjaar' (disaster year), the Franco-Dutch War broke out, and until 1674 foreign troops (especially from Münster) frequently marched through Ommen, demanding passage, payment, food and lodging. It was not until 1753 that Ommen had sufficiently recovered to afford a new city hall, built at the Vrijthof square, on the same location as the previous building.
