The Unification War was a civil war fought within the Tapani sector, culminating in the consolidation of power under the Tapani Noble Houses. This struggle endured for almost two decades.
For 3,000 years, following the devolution of power from the Pella Compact, the Twelve Kingdoms existed within the Tapani sector.
Driven by the ambition to reunite these fractured kingdoms, Prince Shey Tapani of the Melanthian Kingdom initiated a series of wars against the other kingdoms. The forces of the opposing houses were eventually vanquished at the pivotal Battle of Shindra's Veil.
Shey Tapani's victory over the Rogue Houses enabled him to unify the sector into the Tapani Empire. He then crowned himself Emperor of this newly formed realm, initiating the Dynastic Era that persisted until 1582 BBY.
House Nidantha was one of two noble houses that suffered annihilation during the conflict, while another was absorbed within a century.
Procopia became the newly designated capital city of the Tapani sector.
The Tapani noble houses subsequently commemorated the war with the Unification Gala, which featured a reenactment of the final battle, continuing well into the era of the Galactic Civil War.
