Ukuhero, officially the Democratic Commonwealth of Ukuhero, is a country in the weiMC Minecraft server.

The history of Ukuhero traces its origins to the Japanese colonization of present-day Cape Samu. Acquired during the expansion of the Empire of Japan, the island, then known as Samumisaki (Japanese: 寒岬, lit. “the cold cape”) initially served as a penal colony for low-risk political prisoners and a settlement for a large population of Burakumin. Following World War II, the territory was seized by British Armed Forces along with the neighboring region of Ukuhero (Japanese: 宇久兵呂, derived from the Māori Uku Whero, meaning 'red clay').

Under British administration, the territories were organized into two separate Crown Colonies: Cape Samu and New Elizabeth, and a huge wave of immigration would flow into the colony. In 1983, the reformist New Elizabeth Nationalist Party (NENP) assumed political leadership, successfully petitioning for a referendum on sovereignty, which was firmly rejected. On December 25, 1984, the territory transitioned to independence as the Commonwealth of Ukuhero, a constitutional monarchy maintaining ties to the British Crown following the Ukuhero Civil War. During this time, Cape Samu would be handed over to Australia from the United Kingdom as a territory.

On December 25, 1989, the fifth anniversary of independence—Cape Samu was officially integrated into the Ukuhero from Australia following a period of civil unrest and mass independence protests. Upon its handover, Cape Samu replaced Ukuhero City (now Sunazakai) as the national capital. During this time, a republican movement primarily lead by the Labor Movement for Socialism, a revolutionary socialist splitoff from the Labor Party following emphasis on working within state structures, would begin, building the framework for modern-day Ukuhero.

Labor, under the leadership of Yutaro Miyazaki, would officially settle a deal with the LMS to advocate for putting an end to the constitutional monarchy, and advocating for a non-monarchist state. On January 1st, 2010, the British crown would officially end their tenure as head of state following reorganization into the Democratic Commonwealth of Ukuhero alongside a new constitution.
