The Great Zab (Arabic: الزاب الكبير‎ (al-Zāb al-Akbar), Turkish: Zap, Kurdish: Zêy Badînan, Syriac: ܙܒܐ ܥܠܝܐ (zāba ʻalya)) is an approximately 400-kilometre (250 mi) long river flowing through Turkey and Iraq. It rises in Turkey near Lake Van and joins the Tigris in Iraq south of Mosul. The drainage basin of the Great Zab covers approximately 40,300 square kilometres (15,600 sq mi), and during its course, the rivers collects the water from a large number of tributaries. The river and its tributaries are primarily fed by rainfall and snowmelt – as a result of which discharge fluctuates highly throughout the year. At least six dams have been planned on the Great Zab and its tributaries, but construction of only one, the Bekhme Dam, has commenced but was halted after the Gulf War.

The Zagros Mountains have been occupied since at least the Lower Palaeolithic, and Neanderthal occupation of the Great Zab basin has been testified at the archaeological site of Shanidar Cave. Historical records for the region are available from the end of the third millennium BCE onward. In the Neo-Assyrian period, the Great Zab provided water for irrigation for the lands around the capital city of Nimrud. The Battle of the Zab – which ended the Umayyad Caliphate – took place near a tributary of the Great Zab, and the valleys of the river provided shelter for refugees from the Mongol conquest of Iraq. During the 19th and 20th centuries, the Great Zab basin saw frequent uprisings of local Kurdish tribes striving for autonomy.

Judah made his professional debut as an 18 year old on September 20, 1996, in Miami, Florida and defeated Michael Johnson by technical knockout in the second round. After winning bouts over George Crain and Omar Vasquez in May and June 1997 respectively, Judah closed the year with first-round knockouts over Cesar Castro, James Salava and Ricardo Vasquez. Judah began 1998 by knocking out Steve Valdez in the first round in January. Valdez, who had never been stopped in his career, went down four times in the fight. In March, Judah and his opponent, Esteban Flores, accidentally clashed heads in the second round, causing a cut to open above Flores' eye and the bout was stopped in round three as Flores could not continue because of the cut. The bout went into the books as a technical draw, but the result was changed to a no contest in May 1998. On April 14, 1998, Judah battered two-time Dominican Republic champion Angel Beltre, stopping him in the second round.
