The district is relatively new, having been part of Kitgum District in the past. In December 2001, Aruu County and Agago County were carved out of Kitgum District to form Pader District. The seat of the district government, Pader, is located in the center of the district. The district, along with Amuru District, Agago District, Gulu District, Lamwo District, Nwoya District and Kitgum District, constitutes Acholi sub-region, considered to be the historical homeland of the Acholi ethnic group, and home to an estimated 1.1 million inhabitants in 2002, according to the national census conducted that year.
The Pader is a river in North Rhine-Westphalia, Germany, left tributary of the Lippe. It runs through the city of Paderborn, which it gave its name. Although fairly wide, it is only 4 km in length which makes it the shortest river of Germany.
