Since the presidential elections in 2015, Tanzania's opposition has been restricted by a ban on opposition rallies and the stifling of independent media, sanctions, intimidation, and punishment of citizens for criticising President John P. Magufuli of the ruling Chama cha Mapinduzi (CCM, Swahili for 'Revolutionary Party'). 
Tangu uchaguzi wa Rais wa mwaka 2015, upinzani Tanzania umekatazwa kufanya maandamano na vyombo vya habari vya kujitegemea vimefungiwa, kumekuwa na vikwazo, vitisho, na wananchi kuadhibiwa pale wanapomkosoa Rais John P. Magufuli wa Chama kilichoshika dola, Chama cha Mapinduzi (CCM).
