Question: The country which contains Ukum got its name from what?

full_context: Document 1: Nigeria: In 1885, British claims to a West African sphere of influence received recognition from other European nations at the Berlin Conference. The following year, it chartered the Royal Niger Company under the leadership of Sir George Taubman Goldie. In 1900 the company's territory came under the control of the British government, which moved to consolidate its hold over the area of modern Nigeria. On 1 January 1901, Nigeria became a British protectorate, and part of the British Empire, the foremost world power at the time. In the late 19th and early 20th centuries the independent kingdoms of what would become Nigeria fought a number of conflicts against the British Empire's efforts to expand its territory. By war, the British conquered Benin in 1897, and, in the Anglo-Aro War (1901–1902), defeated other opponents. The restraint or conquest of these states opened up the Niger area to British rule.
Document 2: Nigeria: The name Nigeria was taken from the Niger River running through the country. This name was allegedly coined in the late 19th century by British journalist Flora Shaw, she was inspired by the name of the river, in preference to terms such as "Central Sudan". The origin of the name ''Nigeria'' came from the name of the Niger River. The word ( Niger )  is an alteration of the Tuareg name egerew n-igerewen used by inhabitants along the middle reaches of the river around Timbuktu prior to 19th-century European colonialism. Egerew n-igerewen means River of the Rivers.

Nri and Aguleri, where the Igbo creation myth originates, are in the territory of the Umeuri clan. Members of the clan trace their lineages back to the patriarchal king-figure Eri.

Document 6: Nigeria: Modern-day Nigeria has been the site of numerous kingdoms and tribal states over the millennia. The modern state originated from British colonial rule beginning in the 19th century, and the merging of the Southern Nigeria Protectorate and Northern Nigeria Protectorate in 1914. The British set up administrative and legal structures whilst practising indirect rule through traditional chiefdoms. Nigeria became a formally independent federation in 1960, and plunged into a civil war from 1967 to 1970. It has since alternated between democratically-elected civilian governments and military dictatorships, until it achieved a stable democracy in 1999, with its 2011 presidential elections being viewed as the first to be conducted reasonably freely and fairly.
Document 7: Sawaba: Sawaba was an outgrowth of several sources, and passed through several name changes prior to Niger's independence from France in 1959-1960. Under first the French Union and then the French Community, the colonies of French West Africa began to develop semi-autonomous political institutions in the decade and a half of the French Fourth Republic. Territories, like Niger, were granted consultative posts, first to the colonial government of West Africa (in Dakar), and later in Territorial Assemblies. These bodies had very limited powers, limited seats for Africans, and those elected were chosen by a very restricted electorate.
Document 8: Nigerian nationalism: Nigerian nationalism asserts that Nigerians are a nation and promotes the cultural unity of Nigerians. Nigerian nationalism is a territorial nationalism, emphasizing a cultural connection of the people to the land -- in particular the Niger and Benue rivers. It first emerged in the 1920s under the influence of Herbert Macaulay who is considered the founder of Nigerian nationalism. It was founded because of the belief in the necessity for the people living in the British colony of Nigeria of multiple backgrounds to unite as one people in order to be able to resist colonialism. The people of Nigeria came together as they recognized the discrepancies of British policy. ``The problem of ethnic nationalism in Nigeria came with the advent of colonialism. This happened when disparate, autonomous, heterogeneous and sub - national groups were merged together to form a nation. Again, the colonialists created structural imbalances within the nation in terms of socio - economic projects, social development and establishment of administrative centres. This imbalance deepened the antipathies between the various ethnic nationalities in Nigeria (Nnoli, 1980; Y oung, 1993 and Aluko, 1998). ''The Nigerian nationalists' goal of achieving an independent sovereign state of Nigeria was achieved in 1960 when Nigeria declared its independence and British colonial rule ended. Nigeria's government has sought to unify the various peoples and regions of Nigeria since the country's independence in 1960.
