West Mamucium is a department of Nedlando-Khorasan founded on 3 March 2017. Mamucium is located in Greater Manchester, Northern England, and borders the Mahusetan Mamucian Republic.
The original Republic of Mamucium was declared by Hasan Çakar on 22 September 2016, ceceding from the United Kingdom. Mamucium then petitioned to join the Confederation of Mahuset. The United Kingdom neither recognized nor reacted to Mamucium's secession. Mamucium's annexation was unanimously supported by the Lazian Chamber and at 20:00pm (BST), Mamucium became the fourth territory of the Confederation of Mahuset. On 24 October 2016, founder Hasan Çakar stepped down as leader of Mamucium and handed over full power to Mahusetan president Emiel Hardy. Hasan Çakar returned as leader of Mamucium on 25 January 2017.
On 3 March 2017, West Mamucium was created as a new territory by Çakar, and was granted as a gift to Nedland.
West Mamucium is surrounded by the United Kingdom and Mahuset, bordering a primary school and a farm. West Mamucium's territory is mostly flat grassland, however there are fully grown blackberry bushes and hawthorn trees near the northern border areas of the territory. West Mamucium claims a field with a wild horse reservation, and an adjacent factory. West Mamucium's territory is uninhabited, however, there is an occasional police presence near the area.
