The border wars are a series of conflicts between Ravka and its bordering nations, Shu Han and Fjerda. They have been ongoing for centuries. According to Yuri Vedenen, the wars date back to Ravkan unification under Yaromir the Determined, and likely go back even further.
Borders, territories, and alliances shift over time with various gains and losses. By the beginning of Shadow and Bone in particular, Ravka is in a vulnerable situation due to a combination of obsolete strategy and a failure to innovate, the Shadow Fold weakening the economy, and Ravka's enemies keen to take advantage. The conflicts have left many children orphaned and spouses widowed.
