Muhammadu Buhari, who served as Nigeria's President from 2015 until earlier this year, has passed away at the age of 82 in a London clinic. Initially traveling to the UK for a routine medical check-up in April, Buhari's condition deteriorated, leading to his eventual demise.

Known for his austere demeanor and military background, Buhari was both revered and criticized during his time in office. After three unsuccessful attempts, he achieved a historic electoral victory in 2015, becoming Nigeria's first opposition candidate to defeat an incumbent. His popularity was significant among the poorer populations, especially in the northern regions, referred to as "talakawa" in Hausa.

Throughout his presidency, Buhari made several promises including tackling corruption, nepotism, and addressing youth unemployment. However, his tenure coincided with significant economic hardship, largely due to a global oil price slump and rising insecurity issues. Buhari had vowed to combat the Islamist militant group Boko Haram, but the group remains a significant threat even after his promises.

Buhari's administration faced criticism for its handling of various crises, including clashes between farmers and ethnic Fulani herders, as well as the surge of kidnappings by armed groups. Furthermore, human rights violations were reported under his leadership, notably during protests against police brutality.

Born in December 1942 in Katsina State, Buhari was the son of a Fulani father and a Kanuri mother. He received military training after Nigeria gained independence and steadily rose through the ranks to become a key military leader. His tenure as military ruler from 1983-1985 spun controversy due to his harsh measures aimed at curbing corruption.

After his earlier ousting from power, Buhari ventured into politics, advocating for multiparty democracy. Upon assuming the presidency in 2015, he emphasized his integrity and modest lifestyle, contrasting with Nigeria's often corrupt political landscape. However, rising food prices and other economic challenges led many Nigerians to lose faith in his leadership over time.

As he transitioned from military ruler to democratically elected president, Buhari's legacy remains a subject of debate, underscored by his health issues which sometimes hindered his governance. His passing marks the end of a significant chapter in Nigerian politics, as the nation now reflects on a complex and often contentious leadership. Buhari is survived by his wife, Aisha, and their 10 children.
