For its first 14 years as an independent state Niger was run by a single-party civilian regime under the presidency of Hamani Diori. The 1960s were largely peaceful, and saw a large expansion of the education system and some limited economic development and industrialisation. Links with France remained deep, with Diori allowing the development of French-led uranium mining in Arlit and supporting France in the Algerian War. Relations with other African states were mostly positive, with the exception of Dahomey (Benin), owing to an ongoing border dispute. Niger remained a one-party state throughout this period, with Diori surviving a planned coup in 1963 and an assassination attempt in 1965; much of this activity was masterminded by Djibo Bakary's MSA-Sawaba group, which had launched an abortive rebellion in 1964. In the early 1970s, a combination of economic difficulties, devastating droughts and accusations of rampant corruption and mismanagement of food supplies resulted in a coup d'état that overthrew the Diori regime.
