Kano is a city in Nigeria and the capital of Kano State in Northern Nigeria. Its metropolitan population is the second largest in Nigeria after Lagos. The Kano Urban area covers 137 km² and comprises six Local Government Area (LGAs) - Kano Municipal, Fagge, Dala, Gwale, Tarauni and Nassarawa - with a population of 2,163,225 at the 2006 Nigerian census. The Metropolitan Area covers 499 km² and comprises eight LGAs - the six mentioned above plus Ungogo and Kumbotso - with a population of 2,828,861 at the 2006 Nigerian census.

The principal inhabitants of the city are of the Hausa people. As in most parts of Northern Nigeria, the Hausa Language is widely spoken in Kano. The city is the capital of the Kano Emirate, and the current Emir, Ado Bayero, has been on the throne since 1963. The city is home to the Mallam Aminu Kano International Airport, the main airport serving northern Nigeria and was named after Nigerian politician Aminu Kano.

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.

Jack Bauer is the protagonist of the American television series 24. His character has worked in various capacities on the show, often as a member of the fictional Counter Terrorist Unit (CTU) based in Los Angeles, and working with the FBI in Washington, D.C. during season 7. Within the 24 storyline, Bauer is a key member of CTU and is often portrayed as their most capable agent. Bauer's job usually involves helping prevent major terrorist attacks on the United States, saving both civilian lives and government administrations. On many occasions Jack does so at great personal expense, as those he thwarts subsequently target him and his loved ones. Bauer's frequent use of torture to gather information has generated much controversy and discussion. Entertainment Weekly named Jack Bauer one of The 20 All Time Coolest Heroes in Pop Culture.
