The German Kalisyndikat GmbH (short: Kalisyndikat) was a German economic cartel of Kali -Industrie. It was founded in 1904 and reformed due to a change in the law in 1910 and later in 1925. The roots reach almost 30 years back to 1890, when in Staßfurt - Leopold Hall, the birthplace of potash mining in Germany, founded "German Kalisyndikat". The syndicate's HQ was there until 1910 before it was relocated to Berlin (see BSG.BS.02120). See Wikipedia.
