the North Atlantic Treaty Organization in 1966. After that, from 1967 until 1994, the Canadian NATO forces (CFB Lahr) maintained their European headquarters in Lahr. Following the closing down of the "old" Brigade Area in North Rhine-Westphalia centred around Iserlohn, Hemer, Deilinghofen as well as Werl and Soest (1970–1971)the Land Forces and their families were transferred to the Lahr area to join the existing Air Force contingent. On 6 May 1994, Werner Dietz, Mayor of Lahr/Schwarzenwald presented the Canadian Forces a plaque "The City of Lahr/Schwarzenwald, in the Black Forest, thanks the Canadian Forces for their contribution to Peace, Security and harmonious relations between Canadian and German populations of our city during their presence from 1967 to 1994." After the Canadian Forces left in 1994, a small Canadian contingent of former civilian employees remained in Lahr (approximately 200). As early as 1939 Lahr was the seat of the rural district of the same name. Its automobile license plates code was "LR" but during the Baden-Württemberg district reform in the 1970s the district was dissolved and its communities were assigned and made part of the newly created Ortenau District. The boroughs Lahr's boroughs also enjoy a long history. Hugsweier, Burgheim, Dinglingen, Langenwinkel, Mietersheim and Sulz used to be ruled by the same rulers as Lahr itself and therefore shared a great deal of the city's history. In 1803 they became part of Baden and were communities in a previous district of Lahr until they were merged and became part of the city. Hugsweier was first mentioned in 1341 as "Hugelswilre", Burgheim in 1035 as "Burcheim", Dinglingen in 961 as "Tuntelinga", Mietersheim in 762 as "Mutherisheim" and Sulz in 1270 as "Sulz". Langenwinkel is a village with a fairly short history. It was built starting in 1787 in the area of the Nassau forest, which was cut down to make room for the new village, on land that belonged to Dinglingen. In 1790 the first house was built and in 1797 Langenwinkel became an independent community that was also made part of Baden in 1803. After 1951 the airfield for the Canadian Forces was built in Langenwinkel's immediate vicinity and the associated noise and traffic became a tremendous hardship for the residents of Langenwinkel. In 1965 the German Ministry of Defense decided therefore to move the village and Langenwinkel was recreated between 1968 and 1971 several kilometres southeast of the Hurster Hof.
