When a civilian government was reinstated in Nigeria in 1999, many of those living in the Niger Delta region, the source of Nigeria's oil wealth, hoped that a "democratic dividend" would end decades of neglect they had suffered under successive military regimes. From the early 1990s a cycle of protest and repression had led to the militarization of large parts of the delta, notably in Ogoniland, a small area of Rivers State where demonstrations leading to the closure of oil production had led to a five-year deployment of a special military taskforce to the area and the 1995 execution of nine minority rights leaders, including author and activist Ken Saro-Wiwa. The situation has eased under the new government, and in particular Ogoniland is no longer occupied. But there is still widespread deployment of army, navy, and paramilitary Mobile Police at oil facilities across the delta.
