The city was founded in 1970 out of the formerly independent villages of Willich, Anrath, Schiefbahn and Neersen, although the villages are much older. Anrath was mentioned for the first time in 1010, Willich in 1245, Neersen in 1262 and Schiefbahn in 1420. The villages belonged to the Electorate of Cologne until the French Revolutionary Wars when they were occupied and annexed by France in 1794. At the end of the Napoleonic Wars in 1815 the villages fell to the Kingdom of Prussia.
1891-1945
In 1891 a tornado devastated Anrath. The village was already impoverished by the decline of previously dominant domestic weaving and now the municipal administration of Anrath even considered a dissolution of the village. To improve the economic situation a royal prison was built. It was completed in 1905. In 1908 Stahlwerk Becker was built and up to its closing in 1932 was one of the largest employers in Willich. Under a new owner, the mill was reopened in 1934 and was used to manufacture military supplies. The factory was finally closed in 1945 and the grounds were converted to a military base for the British Armed Forces. During World War II, Willich suffered only minor damage to its infrastructure. During Operation Grenade on March 1, 1945 American forces which had entered Schiefbahn met a counterattack from a German Panzer unit. Heavy fighting erupted, with both sides suffering numerous casualties. During the 19th century more than 100 Jews lived in the four villages. During the Third Reich, the Nazis deported 40 Jews - of which 38 were ultimately murdered in the Nazi death camps.
The British Army had soldiers stationed in Willich for more than 40 years: 40 Army Engineer Support Regiment, which by the early 80s was reduced down to 40 Army Engineer Support Group. Both units belonged to the Royal Engineers. In 1992 the camp was closed and the group disbanded. In July 2009 a reunion took place in the old camp. 141 attended the evening event. There was a reunion again in 2012 with over 200 joining in the complete weekend.
