The Worsian War was a war between Calicia and Worsia, originally declared by King Andrick I of Calicia against King Jenner I of Worsia. King Jenner I died in 419, leaving the throne to his son King Taruss I of Worsia. King Taruss surrendered to Calicia a year later.

Since then, there has always been tense relations between Calicia and Worsia, even though Worsia is now a region of Calicia.
