モレネ
The First World War resulted in the end of neutrality. On 4 August 1914, Germany invaded Belgium, initially leaving Neutral Moresnet as "an oasis in a desert of destruction". A total of 147 Neutral Moresnet citizens were killed, though it is unclear whether they were killed inside the territory or in fighting outside its borders. On 27 June 1915, Neutral Moresnet was annexed by the Kingdom of Prussia, although the annexation never received international recognition.
