I argue that navigating Lingala represented a central part of many Zairians’ experiences of Mobutu’s regime (1965–97), causing linguistic change, shaping their relationships to state power, and influencing their experiences of the regime’s everyday authoritarianism. Mobutu’s regime imposed Lingala through informal language practices including political rallies, songs, and slogans, interactions with state agents, and Mobutu’s own practice of addressing audiences nation-wide in Lingala. Zairians navigated the regime’s imposition of Lingala in different, and often divergent ways along a spectrum from rejection and opposition to acquisition and embrace. Where some Zairians, especially Kiswahili speakers in the East, rejected Lingala and criticized the language — critiquing Mobutu’s authoritarian rule in the process — other Zairians, particularly people in the Kikongo and Ciluba national language zones adapted to Mobutu’s new linguistic dispensation by learning to speak and understand Lingala, improving their relationship with the state and facilitating life under Mobutu’s rule.
