Kreis Hohensalza ([ˌhoːənˈzalt͡sa]) was one of many Kreise (districts) in the northern administrative region of Bromberg, in the Prussian province of Posen from 1815 to 1919. Its capital was Hohensalza (Inowrocław).
Kreis Hohensalza, known as Kreis Inowrazlaw until 1904, was a Kreis (district) in the northern administrative region of Bromberg, in the Prussian province of Posen. It was located within the Bromberg Government Region, first in the Grand Duchy of Posen (1815-1848, in personal union with Prussia) and then in the Prussian Province of Posen (1848-1919). On January 18, 1871, the Kreis, along with all of Prussia, became part of Germany. Kreis Hohensalza was part of the military command (German: Bezirkskommando) at Hohensalza (Inowrocław). The main regional court (German: Landgericht) was in Bromberg (Bydgoszcz), with a magistrate's court (German: Amtsgericht) in the capital city Hohensalza (Inowrocław).
On 1 July 1886 southern areas of the district were separated and became part of the new Kreis Strelno. The capital city, formerly known as Inowrazlaw, was renamed Hohensalza on 5 December 1904, and the county name also changed by default. In the course of the Greater Poland uprising in 1919, the southern part of the district came under Polish control, while the northern part with Argenau (Gniewkowo) remained under German control. Following the Treaty of Versailles in July 1919, Germany also ceded the northern part of the district to Poland between 17 January and 4 February 1920. The territory then became part of the Second Polish Republic.
During World War II, the territory of the former Kreis was annexed by Nazi Germany and Landkreis Hohensalza (Wartheland) was established, which existed from 1939 to 1945.
The district had a Polish majority population, with a significant German minority.
