He was born in the Ibibio area of Akwa Ibom State and attended Methodist College, Uzuakoli. After completing his secondary education, he proceeded abroad to study at Trinity College, Dublin with the support of his community and the Ibibio Union, an organization which he later led. At TCD, he served as President of the University Philosophical Society, the student debating society. He later earned a postgraduate degree at Oxford University. His mother, Madam Adiaha Edem Udo Udoma, a women’s leader and over 400 women in Opobo Division were killed by colonial troops and police in their struggle to stop women’s taxation in 1929. He returned to Nigeria to practise law in the mid-1940s, but became intrigued and moved by the nationalistic politics of the time. At the time, Nigeria was attracting returning emigrants who had left previously. He joined the National Council of Nigeria and the Cameroons early on, but left the party following a crisis in the former Eastern Region that saw the removal of Eyo Ita, an Ibeno man from office as the leader of the Eastern Region by Azikiwe. From 1953 to 1959, Udo Udoma was a member of the federal House of Representatives, under the platform of the United National Independence Party, then he was a leading proponent for the creation of a Calabar/Ogoja/Rivers state. However, his failure to succeed in the creation of an independent region or state in south-eastern Nigeria, and the triumph of the three major regions at a constitutional conference in 1958, led him to concede politics to the dominant parties. He spent four years as a High Court judge before he was appointed Chief Justice in Uganda. He was a knight of the British Empire and also belonged to the group that championed Nigerian independence from Britain and was one of the founding fathers of Nigeria. He died at the age of 80 on 2 February 1998.
