The '''Frontier War''' ({{wp|German language|Vierz}}: ''Grenzkrieg'', {{literal translation}} "Border War") was a four-year {{wp|armed conflict}} between the [[Vierz Empire]] and [[Vonzumier]]. The war began on 14 May 1915 when Vonzumier declared war on Vierzland, and it ended on 7 March 1919 when a Tieradan-brokered armistice was signed. The war broke out after Vierzland provoked Vonzumier after years of {{wp|Territorial dispute|disputes}} over the [[Darbut Lakes]] since the end of the [[Vonzumierian Revolutionary War]]. Vonzumier aimed to gain sovereignty over the region and gain the respect of the Patyrian power, while Vierzland wanted to humiliate Vonzumier and cement its [[Vierz colonial empire|colonial rule]] over the northern end of [[South Artalia]].

After Vonzumier's declaration of war, Vierz forces made the first moves on the battlefield. They took advantage of an under-equipped and poorly-trained [[Vonzumierian Armed Forces|Vonzumerian military]], but by 1917 were forced into a stalemate situation after a number of costly battles. Vonzumier received the support of [[Tierada]], [[Apelia]], [[People's Republic of Luepola|Luepola]], and others, who aimed to undermine Vierz geopolitical power.

Economic difficulties, military defeats, falling morale, and war-weariness at home led [[Emperor of Vierzland|Vierz emperor]] [[Victor II]] to seek an armistice with Vonzumier, brokered by [[Tierada]]. The [[Treaty of Luchtenburg]] resulted in the transfer of a broad strip of Vierz land in South Artalia to Vonzumier, including the [[Amplian Ocean|Amplian]] seaport of [[Opnacht]].

The war was significant in human history for its brutality; {{wp|chemical weapons}}, {{wp|human wave}} attacks, and {{wp|trench warfare}} were commonplace. The conflict saw the first use of the {{wp|tank}} in the history of war, as well as the first widespread use of {{wp|machine guns}} and {{wp|Airplane|airplanes}}. It is estimated that anywhere between 2 million and 3 million people died as a result of the conflict, most of whom were civilians that perished from disease and hunger due to the pervasive destruction laid to civilian infrastructure.

The result of the conflict had an immense social, cultural, and political impact in both Vierzland and Vonzumier. Vonzumier's sovereignty as an independent state was cemented by its {{wp|total victory}}; national honour and patriotism were at an all-time high. Vierzland, however, was humiliated by its former colony, and national opinion was intensely cynical and bitter. The consequences of this would lead to a number of geopolitical developments in the 1920's that eventually resulted in the breakout of the [[Great War (Vasarden)|Great War]].
