Collective Strategic Defense Organization

The Collective Strategic Defense Organization (CSDO; Kadolhan: Збиратељство дєлуюћег одбрамбеног удружења, Zbirateljstvo djelujućeg odbrambenog udruženja) is an intergovernmental military alliance that was first signed by Kadolha and Bloodia on 1 March 1950 as a result of the formation of the Sajuz. The 1991 Bloodian invasion of Sataria and Kadolhan invasion of North Lubilia was the largest military operation undertaken by the two leading nations, officially dissolving the Sajuz. Bloodia announced their withdrawal from CSDO in 1992, after allowing the then semi-recognized state of Lipnitia-Lubilia to form, which also in turn caused the Bloodian-Kadolhan Split.
