The Swetanian-Weranian War was an armed conflict between the Panswetanian Council Republic and the Lands of the Weranic Crown that took place from December 1949 to May 1950 when an armistice was signed, with the war being brought to an end with the Rayenne Treaty in July 1950.

In 1949, as the Weranian Empire in Coius went into collapse and the country became under the increasing control of right-wing, anti-socialist elements, there was growing suspicion that Swetania was undermining the Weranian state and that a preventive war was necessary. Pan-Weranicism also underwent a small revival in Werania, whilst domestic troubles due to increasing right-wing and royalist terrorism in Swetania led the Weranic government to conclude that a Weranian invasion of the country would be approved by the majority of the Swetanian population, particularly its Weranic speaking citizens.

In December 1949 the Reichswehr launched a surprise attack on Swetania, with panzer divisions crossing the border. The Weranic airforce also launched a raid in an attempt to destroy the Swetanian airforce; this ploy failed significantly handicapping Weranic planes. From December to February, the Weranic army made large advances into Swetania primarily utilising blitzkrieg; by the beginning of February 1950 the Weranic army had occupied around a third of Swetania and much of its northern industrial centres. A further advance under Operation Kingfisher led to a successful Swetanian counterattack, who through deep operation warfare that halted the Weranic advance at the Battle of Steenwiesen. Swetanian forces soon launched their own offensive that decimated Weranian forces and forced them into a retreat. After the battle of Grenfurt which saw the Weranic Eastern Army Group encircled and destroyed in April, Werania's army rapidly lost ground and by May 1950 had been pushed back to the Justa river.

The destruction of a large section of the Weranic army and success of Swetanian forces led to neighbouring countries such as Estmere - whose relations with Swetania were poor - to consider an intervention against Swetania. A failed coup against the Weranian government led to a change in leadership and collapse of influence by hardliners in the government, replaced with politicians eager to conclude a peace with Swetania. Despite having the capability to advance, Swetanian leaders worried of a coalition against their country entered an unexpected ceasefire with Werania over the Justa river and started peace talks through the Community of Nations.

The Treaty of Rayenne saw the armistice border finalised, with Swetania gaining the wealthy industrial region of the Zingebirge Basin and Western Uschupes, whilst Werania gained the smaller region of the Acupis strip. The success of Swetanian forces confirmed it as the most powerful country in northern Euclea and emboldened socialists abroad. In Werania the de facto defeat of its armed forces and of the militarist factions in government led to the country to abandon its policy of attempting to position the Weranic Empire as a superpower and began a process of rapid decolonisation, whilst beginning to enter a period of integration into the Euclean Community. The war also started the development of nuclear weapons in both countries.
