Yinchorri Uprising

The Yinchorri Uprising, also known as the Yinchorri Crisis, represented a series of aggressive actions by the Yinchorri in 33 BBY. After joining the Galactic Republic in 58 BBY, the Yinchorri were quick to embrace the inflow of technology and commerce. A military force was rapidly developed and dreams of conquest inhabited their minds. Provoked by Darth Plagueis and Darth Sidious, with the help of Vilmarh Grahrk, the Yinchorri seized the Golden Nyss Shipyards before invading the nearby moon of Mayvitch 7. In fact, Plagueis wanted to see if the Yinchorri were worthy to host a secret cloned army for the destruction of the Jedi.

The Jedi Order sent a diplomatic mission to investigate the situation, but the two Jedi assigned were murdered. In response, the Order dispatched a larger force consisting of Jedi Masters and Jedi Knights, but were immediately attacked upon arrival in the Yinchorri system. After a series of bloody battles scattered on Yitheeth, Yibikkoror, and their homeworld of Yinchorr, the Jedi were able to pacify the Yinchorri with the aid of the Judicial Forces during the decisive Battle of Uhanayih. Subsequently, Yinchorr was placed under interdict by the Republic.

The Sith's victory was threefold. First, seven Jedi (including one member of the Jedi Council) were killed. Second, the Yinchorri—aggressive, expansionist, armed with cortosis, and immune to mind tricks—would have posed a threat to his plan to rule the galaxy, and he was able to manipulate others to solve the problem for him. Third, Supreme Chancellor Finis Valorum's political standing in the Galactic Senate was critically weakened, paving the way for Senator Palpatine's own rise.
