Yan Tatsine
The Yan Tatsine were followers of the controversial Nigerian Islamic leader Maitatsine that first appeared around the early 1970s. Activity

1980 events

The era of 1970-1980 witnessed the rise of Mohammed Marwa, a Cameroonian who inspired thousands to rise up against the existing political and religious order in Nigeria. The group's mission under Maitatsine was the "purification" of Islam which, according to them, was corrupted by the West, and its modernization. As Maitatsine's support increased in the 1970s, so did the number of confrontations between Yan Tatsine and the police. By December 1980, continued Yan Tatsine attacks on other religious figures and police forced the Nigerian army to become involved. Subsequent armed clashes led to the deaths of around 5,000 people, including Maitatsine himself. Maitatsine died shortly after sustaining injuries in the clashes either from his wounds or from a heart attack. Aftermath
When President Shehu Shagari called for all the foreigners to leave Nigeria, it created the worst international crisis since the end of the civil war in January 1970 and implemented a search of commercial, industrial and residential buildings to ensure their departure which caused tension with neighboring countries and international allies. The United States State Department described Nigeria's actions as "shocking and violation of every imaginable human right". The European Economic Community also criticized it and Pope John Paul II called it ""a grave, incredible drama producing the largest single, and worst human exodus in the 20th century". British politician Michael Foot sent a letter to the Nigerian High Commissioner in London, saying ""an act of heartlessness, and a failure of common humanity". British newspapers also commented with The Guardian saying it was "inhumanity, high-handedness and irresponsibility." South African politician P. W. Botha also criticized Shagari in the situation, comparing him to Adolf Hitler and other white right-wing groups said it was worse than apartheid in South Africa. French media such as the Jeune Afrique ran a front page story "La Honte (The Shame)", saying the situation was "an act of barbarism unparalleled in the world" while Ghana newspaper Ghanaian Times said it was an "electoral gimmick" by the National Party of Nigeria-controlled government to deflect attention from its failures so it could win the 1983 election and also said the illegal alien expulsion was "create mass hysteria by infiltrating Sudan-trained mercenaries into Ghana to subvert the Ghanaian Government". Ghanaian politician Jerry Rawlings said it was a "calculated plot" against the Ghanaian government. Leadership after Maitatsine

Despite Mohammed Marwa's death, Yan Tatsine riots continued into the early 1980s. In October 1982 riots erupted in Bulumkuttu, near Maidaguri and in Kaduna, to where many Yan Tatsine adherents had moved after 1980. Over 3,000 people died. Some survivors of these altercations moved to Yola, and in early 1984 more violent uprisings occurred in that city. In this round of rioting, Musa Makaniki, a close disciple of Maitatsine, emerged as a leader and Marwa's successor. Ultimately more than 1,000 people died in Yola and roughly half of the city's 60,000 inhabitants were left homeless. Makaniki fled to his hometown of Gombe, where more Yan Tatsine riots occurred in April 1985. A final riot occurred in Funtua, Kaduna state in 1987. After the deaths of several hundred people Makaniki retreated to Cameroon, where he remained until 2004 when he was arrested in Nigeria, where he was sentenced in 2006, but later released. Despite the death of Mohammed Marwa, the work of Yan Tatsine has continued in modern times. Banned by the Nigerian government, they took refuge in Cameroon and then re-emerged in the limelight around 1995. Their name changed to Sahaba. Another leader of the Yan Tatsine, Malam Badamasi, was killed in 2009 after a series of armed insurrections, while another had been arrested in connection with the killings of several members of the Sunni salafist group Boko Haram. Bomb-making tools and explosives, AK-47 rifles with several rounds of ammunition were recovered from the leader's home, according to the police, along with a number of swords, daggers and gunpowder. Some analysts view the terrorist group Boko Haram as an extension of the Maitatsine riots. In 2018, the Yan Tatsine group, alongside Boko Haram and Yan Hakika, was listed by Sunni Nigerian scholars as enemies of the Nigerian government, and the council of ulama urged the government under Buhari to provide security forces with adequate equipment. The council called on the FG to establish a Religious advisory council so as to save the country from plunging into any religious war in the future. Ideology
They spoke against the Nigerian government, radios, watches, bicycles, cars and the possession of more money than necessary. Due to their excessive violence, the Yan Tatsine were considered the "grandmother of Boko Haram." The group is said to have prayed five times a day facing Mecca, and used misbaha beads for supplication. Because the group was intensely suspicious of outsiders, and because their uprisings in the 1970’s gave rise to many rumors and apocryphal stories, little reliable knowledge exists of the movement.
