Buharism
Imprisoned and subsequently out of power for 30 years , Muhammadu Buhari contested the 2003 , 2007 , 2011 , and later 2015 presidential elections , winning the last one and defeating the incumbent Goodluck Jonathan . Buharism gradually transformed into a cult of personality and initially enjoyed broad support throughout the country , especially in Northern Nigeria , until the 2019 Nigerian presidential election , which caused a significant decline in Buhari's popularity .
