In the 7th century, Dala Hill, a residual hill in Kano, was the site of a hunting and gathering community that engaged in iron work; it is unknown whether these were Hausa people or speakers of Niger–Congo languages. Kano was originally known as Dala, after the hill, and was referred to as such as late as the end of the 15th century and the beginning of the 16th by Bornoan sources.
The Kano Chronicle identifies
Barbushe, a priest of a Dala Hill spirit, as the city's first settler. (Elizabeth Isichei notes that the description of Barbushe is similar to those of Sao people.) While small chiefdoms were previously present in the area, according to the Kano Chronicle, Bagauda, a grandson of the mythical hero Bayajidda, became the first king of Kano in 999, reigning until 1063.  His grandson
Gijimasu (1095–1134), the third king, began building city walls at the foot of Dala Hill. His own son,
Tsaraki (1136–1194), the fifth king, completed them during his reign.
In the 12th century
Ali Yaji as King of Kano renounced his allegiance to the cult of Tsumburbura, accepted Islam and proclaimed the Sultanate that was to last until its fall in the 19th century. The reign of
Yaji ensued an era of expansionism that saw Kano becoming the capital of a pseudo Habe Empire.
In 1463 Muhammad Rumfa (reigned 1463- 1499) ascended the throne. During his reign, political pressure from the rising Songhai Empire forced him to take Auwa, the daughter of Askiyah the Great as his wife. She was to later become the first female
Madaki of Kano.
Rumfa reformed the city, expanded the Sahelian Gidan Rumfa (Emir's Palace), and played a role in the further Islamization of the city, as he urged prominent residents to convert. The Kano Chronicle attributes a total of twelve "innovations" to Rumfa.
According to the Kano Chronicle, the thirty-seventh Sarkin Kano (King of Kano) was
Mohammed Sharef (1703–1731). His successor, Kumbari dan Sharefa (1731–1743), engaged in major battles with Sokoto.
Fulani conquest and rule
Kano History Museum constructed in the distinctive Hausa architectural style.
At the beginning of the 19th century, Fulani Islamic leader Usman dan Fodio led a jihad affecting much of central Sudan, leading to the emergence of the Sokoto Caliphate. In 1805 the last sultan of Kano was defeated by the Jobe Clan of the Fulani, and Kano became an Emirate of the Caliphate. Kano was the largest and most prosperous province of the empire. This was one of the last major slave societies, with high percentages of enslaved population long after the Atlantic slave trade had been cut off. Heinrich Barth, a German scholar who spent several years in northern Nigeria in the 1850s, estimated the percentage of slaves in Kano to be at least 50%, most of whom lived in slave villages.
The city suffered famines from 1807–10, in the 1830s, 1847, 1855, 1863, 1873, 1884, and from 1889 until 1890.
From 1893 until 1895, two rival claimants for the throne fought a civil war, or
Basasa. With the help of royal slaves,
Yusufu was victorious over Tukur and claimed the title of emir.
British colonization and rule
In March, 1903 after a scant resistance, the Fort of Kano was captured by the British, It quickly replaced Lokoja as the administrative centre of Northern Nigeria. It was replaced as the centre of government by Zungeru and later Kaduna and only regained administrative significance with the creation of Kano State following Nigerian independence.
From 1913 to 1914, as the peanut business was expanding, Kano suffered a major drought, which caused a famine. Other famines during British rule occurred in 1908, 1920, 1927, 1943, 1951, 1956, and 1958.
By 1922, groundnut trader Alhassan Dantata had become the richest businessman in Kano, surpassing fellow merchants
Umaru Sharubutu Koki and
In May 1953, an inter-ethnic riot arose due to southern newspapers misreporting on the nature of a disagreement between northern and southern politicians in the House of Representatives. Thousands of Nigerians of southern origin died as a result of the riot.
Ado Bayero became emir of Kano in 1963. Kano state was created in 1967 from the then Northern Nigeria by the Federal military government. The first military police commissioner, Audu Bako, is credited with building a solid foundation for the progress of a modern society. Most of the social amenities in the state are credited to him. The first civilian governor was Abubakar Rimi.
In the late 60's, a ground tracking station was established on the hill overlooking Kano to track NASA's Mercury and Gemini spacecraft when they passed over Africa.
In December 1980, radical preacher Mohammed Marwa Maitatsine led riots in Kano. He was killed by security forces, but his followers later started uprisings in other northern cities.
After the introduction of sharia law in Kano State in 2000, many Christians left the city. 100 people were killed in riots over the sharia issue during October 2001.

In November 2007, political violence broke out in the city after the People's Democratic Party (PDP) accused the All Nigeria Peoples Party (ANPP) of rigging the November 17 local government elections. (The ANPP won in 36 of the state's 44 local Government Areas.) Hundreds of youths took to the streets, over 300 of whom were arrested; at least 25 people were killed. Buildings set on fire include a sharia police station, an Islamic centre, and a council secretariat. 280 federal soldiers were deployed around the city.
In January 2012 a series of bomb attacks in Kano killed up to 162 people. Four police stations, the State Security Service headquarters, passport offices and immigration centres were attacked. Militants of the Boko Haram claimed responsibility. After the bombings, Kano was placed under curfew.
