During this time, the region's villages ending in -trup emerged, such as Herrentrup, Istrup, Wellentrup, Brüntrup, Tintrup and Höntrup.

In the extensive forests, gangs of robbers also threatened the traffic of the time and the roads in the Blomberg area were secured by six watchtowers.

Steep slopes offered natural protection to the west and south, while to the east and north the city was surrounded by walls, moats, ramparts, and even thorn hedges.

Almost all handicraft businesses in the Blomberg Basin were concentrated in the city, only millers, blacksmiths, wheel makers, cobblers and patch cutters could also settle in the countryside.

The donations were so substantial that a monastery church could be built, which for almost 200 years served as the burial place of Lippe's noble lords and counts.

At a total of five state parliaments in Cappel, the towns and knights decided in 1538 to introduce a Protestant church order for Lippe and Blomberg converted to the Evangelical Lutheran faith.

Sovereign Count Simon VI ordered the evangelical-reformed confession of John Calvin to be introduced in all towns and communities in the County of Lippe.

During the Thirty Years' War (1618-1648), Blomberg was again severely damaged when enemy troops plundered the city in August 1636.

In the course of the war, the Blomberg citizens were hit by a devastating plague epidemic and the population fell from 1640 to 675 people within a short time.

On March 10, 2015, the City Council of Blomberg rehabilitated the victims of the witch trials from a socio-ethical and moral point of view.

A few merchants settled on Blomberg's main streets, the Langen and Kurzen Steinwegs, some of whose stately hall houses from the 16th and 17th centuries have survived to this day.

After the end of the war, Kaiser Wilhelm II abdicated and Philipp Scheidemann proclaimed the republic on November 9, 1918.

Gatherings on the streets were banned, children were no longer allowed to be outside after dark and young people after 9 p.m. After this proclamation, the red flag of the revolution was hoisted at City Hall.

According to recent historical research, the majority of the workers' and soldiers' councils did not belong to the extreme left, but to the MSPD and the moderate members of the USPD.

In the last years of the Weimar Republic, there were violent clashes between supporters of the KPD and NSDAP in Lippe, as in the entire Reich, some of which degenerated into hall battles and shootings.

The last Jewish resident of Blomberg was 70-year-old Emma Lippert, née Examus, who was deported to the Theresienstadt concentration camp and on to Minsk , where she was murdered.

US soldiers cleared the anti-tank barriers at the dairy and did not encounter any significant resistance since the SS units had left the city earlier.

Blomberg was handed over by the mayor on April 5, 1945 and occupied by the Americans without a fight while their tanks continued to Hagen and Lügde .

From 1962 to 1996, a Dutch unit of 1,600 soldiers and their family members were stationed on behalf of NATO in the so-called Nederlandspark in the south of the Blomberg industrial area.

On March 7, 2005, French President Jacques Chirac and Federal Chancellor Schröder met in the Burghotel Blomberg.

The district is located in the southern foothills of the Lippe mountain range and in the area of Blomberger and Schwalenberger Heights.

The core city is located in the center of the so-called Blomberger basin, which lies about 150 m above sea level and clearly separates itself from the surrounding area.

The hem of the basin to the north and east are the approximately 400 m high wooded ridges of Barntruper and Blomberger Stadtwald with the Dicker, Becker and Winterberg.

To the west are the Hörntruper Berg, the Meierberg, the Mossenberg (228 m) and the Püllenberg (261 m), while the border in the south of Nessenberg (235 m), Spielberg (239 m) and Steinberg (342 m) is formed.

The rock strata, which were once stored horizontally in the Middle Ages, were raised in the Tertiary around 30 million years ago and formed the Blomberger Sattel.

By erosion in the center of the saddle the older gray and red marl of the Middle Keuper (Km1) were uncovered, which is also called Gipskeuper because of switched-on layers of gypsum.

The outermost edge of the basin structure consists of harder rock layers of the Upper Keuper (Ko) Rätkeuper.

The vast majority of the land is used by agriculture, in the area of wet creek lowlands mainly as grassland and pastures.

The forest on the surrounding mountains consists of three quarters of deciduous trees, mostly beech, while on the Rätkeuper spruce cultures thrive.

The neighbouring communities are Bad Pyrmont, (in Landkreis Hameln-Pyrmont, Niedersachsen), Lügde, Schieder-Schwalenberg, Horn-Bad Meinberg, Detmold, Lemgo, Dörentrup and Barntrup (all in Kreis Lippe).
