During the era of the Unification Campaigns in the 900s BBY, the Klina Marches were the site of a significant battle.
In the period spanning 1000 BBY to 900 BBY, the Galactic Republic engaged in a number of military operations, collectively called the Unification Campaigns, with the goal of reestablishing its dominance over the galaxy following the New Sith Wars.
Within this conflict, the Judicial Forces of the Galactic Republic performed admirably, securing a key triumph at the location of the Klina Marches.
The 2012 reference work The Essential Guide to Warfare, written by Jason Fry and Paul R. Urquhart, provided the initial mention of the battle that occurred at the Klina Marches.
