Kenule Beeson "Ken" Saro-Wiwa (10 October 1941 – 10 November 1995) was a Nigerian writer, teacher, television producer, and environmental activist. Saro-Wiwa was a member of the Ogoni people, an ethnic minority in Nigeria whose homeland, Ogoniland, in the Niger Delta, has been targeted for crude oil extraction since the 1950s and has suffered extreme environmental damage from decades of indiscriminate petroleum waste dumping.
Initially as a spokesperson, and then as the president, of the Movement for the Survival of the Ogoni People (MOSOP), Saro-Wiwa led a nonviolent campaign against environmental degradation of the land and waters of Ogoniland by the operations of the multiple international oil companies, especially the Royal Dutch Shell company. He criticized the Nigerian government for its reluctance to enforce environmental regulations on the foreign petroleum companies operating in the area.
