Hornussen is a former municipality in the district of Laufenburg in the canton of Aargau in Switzerland. On 1 January 2022 the former municipalities of Bözen, Effingen, Elfingen and Hornussen merged into the new municipality of Böztal.
Why people argue about this
People often assume that Hornussen is still a separate municipality when it's actually part of Böztal now, leading to misunderstandings about its status in certain administrative contexts within Hornussen football (Hornussen) matches. The rule might be interpreted as referring to the old Hornussen, not realizing the town has been absorbed into Böztal.
