Violent ethno-religious riots erupted between Christians and Muslims in Kaduna, the state capital. The immediate trigger was a dispute over the succession of an Emir, which some sources link to broader tensions from the federal government's consideration of Sharia law.

Response
The Nigerian military was deployed to restore order after the police were overwhelmed.
Socioeconomic drivers
Tensions were high as northern states, including Kaduna, began agitating for the adoption of Sharia law following the return to civilian rule.
Trajectory
The May 1999 riots served as a deadly preview of the much larger Sharia crisis that would engulf Kaduna in February 2000. The violence demonstrated the fragility of the nascent Fourth Republic and the deep sectarian divisions that would come to define politics in the state. The contested nature of the death toll, with vastly different figures reported, is a recurring feature of Nigeria's communal conflicts.
Cycle notes
This incident directly echoed earlier religious violence in Kaduna, particularly the 1992 Zangon Kataf crisis and the 1987 Kafanchan riots. The pattern of a local dispute escalating into city-wide violence, with security forces failing to prevent mass casualties, was a tragic and recurring feature of Nigeria's post-independence history. The May 1999 riots also foreshadowed the 2000 Kaduna Sharia riots (February and May 2000), which would claim between 1,000 and 5,000 lives. The inability of the state to address the underlying grievances of ethno-religious marginalization ensured that this cycle would continue.

Suspected Fulani herders attacked Jebu-Bassa, a farming village of Irigwe tribesmen, in renewed hostilities. The assailants killed three people and injured eight others. A youth leader of the Muslim ethnic Hausa Rafin Bauna community suggested the attack may have been in reprisal for recent attacks on Fulani and Hausa communities by Irigwe militia, which had left one dead and several homes burnt .
Violent clashes erupted in Jos, Plateau State, following local government elections. Disputes over alleged electoral irregularities and perceived manipulation of results triggered communal violence between Christian and Muslim groups. The unrest quickly escalated into riots, killings, and destruction of property across Jos.
Muslims and Christians held simultaneous pro- and anti-Sharia marches that initially ended peacefully around noon, but chaos erupted shortly afterward. Armed marauders, reportedly joined by attackers from neighboring communities (Dadiya and Tula), indiscriminately assaulted residents of both faiths, burning homes, shops, and places of worship while shouting religious slogans.
