Yuuzhan Vong Invasion

The Yuuzhan Vong invasion was a three-year-long event where the Yuuzhan Vong species invaded the entire galaxy, conquering most of it, then later getting destroyed.

Pre-Invasion
Before the Invasion, the Yuuzhan Vong already had control of much of the Galaxy. Kaiser Jelahan Mozh, leader of the Yuuzhan Vong, was also the leader of the Authority. In an effort to catch the galaxy off-guard, Mozh engineers the Outer Rim Wars. During this time, Mozh splits the entire galaxy and damages many defenses that systems had in place of invasion

Invasion
In 87 ABY, Jelahan Mozh reveals to Alsten Gabbett that he is Onimi, leader of the Yuuzhan Vong. Having his army be a clone army of the late bounty hunter, Jango Fett, Onimi activates Clone Contingency Code 54, genociding the galaxy.

During this time, his Yuuzhan Vong forces were entering the galaxy through The Space Gate on the planet Lehon. Onimi is successful in conquering the galaxy and is relatively unmatched.

The Insurrection
Soon after the genocides, the Insurrection is formed to combat the Yuuzhan Vong threat. They invade Coruscant in an attempt to kill Onimi, however, they are unsuccessful. In a retaliatory attack, Luke Skywalker and his rebels attempt to destroy the Space Gate, which had been relocated to Coruscant. They fail once more and escape to Mandalore.
