By 2007, the relationship between President Tandja Mamadou and his prime minister had deteriorated, leading to the replacement of the latter in June 2007 by Seyni Oumarou following a successful vote of no confidence at the Assembly. The political environment worsened in the following year as President Tandja Mamadou sought out to extend his presidency by modifying the constitution which limited presidential terms in Niger. Proponents of the extended presidency, rallied behind the 'Tazartche' (Hausa for 'overstay') movement, were countered by opponents ('anti-Tazartche') composed of opposition party militants and civil society activists.
