Coruscanti plague

The Coruscanti plague was the name given to a series of rebellions on Coruscant following supply shortages that had surfaced during the Octom War.

Prologue
Although they seemed insignificant at the time, the destruction of the Chemical Vats on Anzat had serious reprecussions throughout the galaxy. Within years, numerous worlds began suffering from supply shortages caused from the lack of chemical filtering needed to keep the food fresh, including Coruscant.

At first the Sith beleived they could simply repair the Vats, but the age old construction methods used to build the Vats was long outdated and a complete reconstruction was required. But this would take time, and until then the planets throughout the galaxy would continue to starve.

Smoking gun
By the year 179 ABY numerous worlds had risen up in protest of the starvations, but none had yet resorted to armed rebellion, seeing no point inn causing needless death.

But a few select individuals on Coruscant had become convinced (correctly) that the Sith were with-holding supplies from the numerous planets in order to root out the rebellious numbers of the population. The rebels convinced many on Corusant of this, and they began to stockpile arms in preperation for armed rebellion.

The Black Guard, the police on Coruscant, had been keeping tabs on many of those who were inciting rebellion and conducted numerous successful raids on several arms warehouses, burning them to the ground. Over ten-million arms were destroyed within six months, but it was not enough.

With the time come, the rebels took too the streets and captured multiple military checkpoints and security stations. The Black Guard were thrown into complete disarray and forced to withdraw from several sections of the planet. But they quickly fought back causing widespread panic and destruction.

Full rebellion
A year passed, and the destruction seemed to be spreading, the Dark Lord, Darth Krayt had called several legions of Sith troopers too Coruscant to assist the Black Guard in the supression of the rebellion but nothing was working.

The Black Guard began resorting to underhand methods in order to flush out the rebels, freezing the bank accounts of numerous families and withdrawing their access to fresh water and electricity. Many families were forced into serious debt, and many Hutt crimelords, like Tadhana flourished. By the year 182 ABY almost half of Coruscant was engulfed by war, plague and poverty. Families all over the planet, even those not from Coruscant, such as the family of Fari Pénzember were forced to sell their holding and leave Coruscant. But things were not going well for the rebels.

Numerous SpecOps assassinations and multiple Black Guard raids had cut rebellion supply lines and decimated their leadership so that by the latter half of 183 ABY the rebels were fighting a lost cause. It would only be a matter of months before the rebellion had collapsed.

Aftermath
Following the rebellion Coruscant was a total wreackage. Darth Krayt's Hand, Darth Talon was tasked with leading the reconstruction and removing any hope of successful rebellion the populous might have still held.

But the end of the war did little to avert the damage already caused, and many families who were put into debt during the conflict were having their debts called. The Black Guard eliminated multiple crimelords but there were many more than the Sith ever expected, meaning multiple families were still being forced into slavery or worse.
