The Kuvexian Invasion of YE 41 was a major invasion of the Kikyo Sector in late YE 41 that was part of the Kuvexian War. Hundreds of thousands of starships, consisting of a combination of military, corporate, mercenary, and pirate forces from the Interstellar Kingdom Of Kuvexia and its allies planned a simultaneous incursion on the Yamatai Star Empire. The invasion's massive scale overwhelmed the Star Army of Yamatai, which began losing star systems to their advance, starting with the Himiko System in the Ketsurui Military Sector (see Fall Of Himiko). Additionally, space piracy began became a major concern throughout the sector.
In the early days of the invasion, Kuvexians conquered UX-11, UX-13, UX-15, UX-16, UX-17, New Vicky (UX-19), UX-20, UX-21, and UX-22. This was quickly followed by Kazumi, UX-1, UX-3, Sbuhfaba, Moriva, Nellrun, and Kimirthro. The invaders began to occupy many unclaimed systems as well, such as Fhasho, Hukka, Nougfran, and Splrug.
The first major battle of the Invasion of YE 41 was the Battle of Hanako's Star, in which the Star Army forces were crushed by the Kuvexians much larger fleets (Kuvexia fielded 14 times as many ships in this case). This resulted in the conquest of Hanako's World.
The Invasion of YE 41 set the stage for the Kuvexian Advance of YE 42.
