The Swiss Civil War (German: Der Schweizer Bürgerkrieg) was a conflict between the Alliance of Central European States (mainly Germany, Austria, and Liechtenstein) and the Swiss Confederation. The conflict began on January 22, 1956, 12 days after the nation of Liechtenstein seceded from the Swiss Confederation. The Swiss issued to Liechtenstein a 24 hour ultimatum, and promptly declared war after their demands were refused. The Alliance of Central European States, which had accepted Liechtenstein into the Alliance only two days prior, declared on the Swiss Confederation and mobilized troops in Germany and Austria. The other members of the Alliance were uninvolved in the conflict, due to being too far from the Swiss Confederation; they were unable to mobilize enough troops in time to make a difference. On January 30, German and Austrian troops stationed near the Liechtenstein border entered the country and engaged the Swiss troops. The Alliance, mobilizing about 590,000 troops, succeeded in defeating the Swiss forces within approximately a month of combat. After Swiss surrender on March 1, 1956, land was seceded to Liechtenstein, and reparation money was to be paid to Germany and Austria.

After the war was over, the Alliance of Central European States met in Berlin to discuss the future of the member nations, finally deciding to unify the member states into a single superstate, which was to be known as the Kingdom of Tenarra. It has since been written in Tenarran history books that the cause of the unification was the Swiss Civil War, and the resulting desire for greater collective security.
