This study investigates conflict-motivated pragmatic acts employed in the open letters exchanged by two former Nigerian presidents (Olusegun Obasanjo and Goodluck Jonathan). The data are analysed using Mey’s pragmatic act theory. The findings reveal that while Obasanjo employs pragmatic acts of warning, appealing, and praising in order to counsel Jonathan, Jonathan employs pragmatic acts of acknowledging, boasting, correcting, and reminding in order to defend himself. However, they both employ the pragmatic acts of insulting, complaining, accusing, and requesting. These acts are influenced by nationalist and anti-ethnic ideologies as well as the context of the open letters, i.e., conflict among political leaders in Nigeria.
