should stay as one unitary state following the threatened secession of Biafra. Personal life He is survived by his wife, two daughters, two sons and six grandchildren. Posthumous Celebration In 1996 a symposium was held at the University of Ibadan to discuss aspects of political science that were regarded as having been influenced by Billy Dudley's writings. On Wednesday, 27 October 2010, the University of Ibadan hosted a ceremony at the Department of Political Science for the unveiling of a memorial plaque remembering Professor Billy Dudley. Books published Of his three books, Parties and Politics in Northern Nigeria was an analysis of the political structures of Northern Nigeria, when the whole of northern Nigeria was a single state - as of 2007, it has been divided into around 19 states, changing the political allegiances. Instability and Political Order: Politics and Crisis in Nigeria was written in 1969–70. It is still of interest for its views on the Nigerian military and the Nigerian Civil War. This book made use of game theory and introduced the use of game theory as an analytical approach in subsequent political science analysis of Nigeria. An Introduction to Nigerian Government and Politics was written in 1979–80, and includes an analysis of the 1979 elections. Although Nigeria has since been through several military and civilian governments, and the constitution has changed, the underlying social and political culture has changed less, keeping the book in demand. Dudley had intended to write an additional chapter to this book, discussing selected political events in Nigeria in the context of internalized values, but he became too ill to do so.
