Six years ago, most Nigerians had not even heard of Boko Haram. Now the whole world is talking about the extremist group that has kidnapped more than 200 schoolgirls in the north of the country. Founded in 2002, how did it rise to become such a threat to national security in such a short period of time?

1. Political connections

It would be naive to think that this kidnap happened in a vacuum, or that the Boko Haram has no connection to the powers that be in Nigeria’s Game of Thrones-style politics. Spikes in violence and insecurity took place on a suspiciously recurring basis in the 12-18 months preceding Nigerian presidential elections: the next election is scheduled for 2015. This tends to be the time that politicians allegedly deploy armed militia to harass, intimidate, or even assassinate their rivals.

In 2012, a senior member, Kabiru Sokoto, was found in a state governor’s house after escaping from police captivity. The year before, a Nigerian senator was arrested on suspicion of aiding the group after claims that he telephoned a militant more than 70 times in one month.

The extremist group is also automatically linked to all kidnappings, violence, and assassinations committed in northern Nigeria — even acts of armed banditry and political assassinations are attributed to it, whether the group claims responsibility for them or not, adding to its reputation and aura.

2. Imbalance between north and south

Seemingly disconnected historical events over the past 60-70 years started the slide into poverty and inequality that eventually led to the formation of Boko Haram. Before Nigeria’s independence in 1960, British colonial authorities ruled the north (where most Muslims live) and south of Nigeria (where most Christians live) separately. Western schools started by Christian missionaries flourished in the south, but Muslim leaders were reluctant to allow Christian mission schools to open in the north.

The long-term result is a massive economic and educational imbalance between the north and south that persists today. In many southern states more than 90 per cent of women are literate. The corresponding percentage is below 5 per cent in some states in the far north. Less than 10 per cent of Nigerian university applicants come from the 12 Muslim majority states in northern Nigeria (where Boko Haram’s insurgency rages). Boko Haram draws its members from the legions of uneducated, unemployed, poor and disenchanted young northern men.

3. Sharia

An overlooked catalyst for Boko Haram’s evolution occurred in 2000 when Ahmad Yerima, the governor of Zamfara state in Nigeria’s north-west, extended the jurisdiction of Sharia to criminal cases, prescribing punishments such as stoning for adultery, amputation for theft and flogging for drinking alcohol. This became a super-charged political issue in the north, as Sharia was popular among Muslims who hoped it would lead to a social and moral revival. Eight other states in northern Nigeria also enacted Sharia in full and Boko Haram’s then leader, Mohammad Yousuf, anticipated it would also be implemented in his home state of Borno. They became disaffected and increasingly hostile to the government when Borno did not implement Sharia in full.

4. Government crackdown

When Boko Haram clashed with police in 2009, the government responded with a military iron fist. Security forces destroyed Boko Haram’s mosque, killed hundreds of its members, and arrested, then summarily executed, its leader Yousuf and his father-in-law. The routing of Yousuf and his followers radicalised Boko Haram even more by eliminating the conciliatory faction within the group, and paving the way for its takeover by its most implacable faction led by Yousuf’s deputy, Abu Bakr Shekau.

5. Nigeria’s complicated ethnic and religious mix

Sensitive ethno-regional issues make it difficult to fight Boko Haram. A massive elephant in the room is that the vast majority of the army’s fighting troops have historically been recruited from ethnic groups in northern Nigeria. Such ethnic groups include the Kanuri — to which most Boko Haram members belong. Unleashing the army on militants means soldiers may be ordered to commit fratricide against communities they come from, who they are not hostile to, and leaves the army vulnerable to infiltration.

Also, an attack by Nigeria’s president Goodluck Jonathan (a Christian from the south) on a northern Islamist group with unrestrained force in the year before a presidential election, would surely result in lost votes amid accusations of being heavy handed with people of another faith.

6. Military limitations

The Chibok schoolgirls are unlikely to be rescued in a spectacular military raid. The Nigerian army is trained for conventional warfare and peacekeeping operations. Elaborate hostage rescues are not its forte. It is having to make ad hoc adaptations to train cadets to carry out counter-terrorism and counter-insurgency operations.

Military offensives can only buy temporary breathing space for politicians to devise permanent solutions to the problem posed by Boko Haram. Some in the military establishment acknowledge that the military alone cannot eliminate the group. Nigeria’s former chief of defence, staff General Martin Luther Agwai (who commanded the United Nations peacekeeping mission in Darfur), said: “You can never solve any of these problems with military solutions...It is a political issue; it is a social issue; it is an economic issue, and until these issues are addressed, the military can never give you a solution.”

A likely outcome to the current stand-off is that the government will negotiate an unwieldy deal with Boko Haram that will see the girls released in instalments.

This would not be unprecedented as the Nigerian government has a history of paying off or reaching uncomfortable opaque compromises with its opponents. When militants waged an armed insurgency in the oil-producing areas of southern Nigeria to protest against economic exploitation, the government ended it by granting amnesty and cash stipends to the militants in exchange for them giving up violence. This has created a “money and amnesty for guns” precedent. Muslim leaders from northern Nigeria have urged the government to similarly negotiate with Boko Haram and to grant it amnesty. With more money and more guns, the group might become more powerful still.
