The Confederation of Independent Systems is the state entity that caused the Clone Wars. The founding of the power by the rebels had obvious reasons. About them and a brief history of this union can be found in this article.
Background to the formation
The Republic had not heard the voices of its citizens for a long time before the Clone Wars. The Galactic Council had internal formations and adopted laws on its own convictions. Corruption grew, taxation of long-distance trade routes upset the guilds that distributed the goods.
The bureaucracy reached its limit, and the Battle of Naboo only strengthened the separatist sentiment in society. Many planets and entire systems wanted to leave the Republic, but this happened with the emergence of a strong leader. He was Count Dooku, who was formerly a member of the Jedi Order. He declared his position to everyone and began to unite alliances of planets around them with their military power. The presence in the Confederation of Independent Systems of organizations of the Corporate Alliance and Techno-Union type indicates a bad situation in the Republic.
Start of conflict
An educated state based its forces on an army of droids. The Trade Federation secretly increased the number of clones after the conflict on Naboo, thereby providing tremendous forces for the rebels, despite an order from the Republic to reduce their numbers. Count Dooku was gaining strength on Coruscant, and Darth Tyranus was hiding under his guise.
New systems joined him, the number of combat drones grew thanks to the help of allied corporations. Their attack should have come as a surprise, but Obi-Wan Kenobi reveals the presence of rebels on Geonosis during the persecution of Django Fett. The Jedi manages to send a signal to Palpatine and his apprentice Anakin Skywalker. Suddenly he was attacked, and Padme and a young Jedi came to the rescue. They fought back for a long time, but were captured. They were awarded death in the arena under the laws of the Confederation of Independent Systems. The situation was corrected by the arrival of Mace Windu and an entire army of Jedi. In the long battle, the numerical advantage of the rebels affected. Soon, the number of Republic fighters was reduced to two dozen.
Continuation of a story
In the Star Wars universe, the Confederation of Independent Systems was uncovered during the events described above. Heroes were saved by the arrival of Master Yoda with the LAAT / i gunboat army. For the next three years, there was a bloody war between two powerful formations. At the beginning of the fighting, the CND won many victories. There were many heroes on their side, including Durge and Asajj Ventress, who considered the war a just cause.
They did not realize that Count Dooku was controlled by Darth Sidious under the guise of Supreme Chancellor Palpatine. The whole war was aimed at seizing power in the galaxy. The republic was able to gather strength and seize the initiative. State forces besieged the Outer Ring. General Grievous at that moment was already brutal, but his plan to attack the Inner Ring almost led to victory. The republic struck back, during the battles the leaders of the KNS troops were killed. The Republic is starting a siege of three key planets again, and the ships of the Confederation of Independent Systems are storming Kashyyyk. Their last maneuver was the capture of the Supreme Chancellor, initiated by General Grievous, but at that moment a message came about the death of Dooku.
The end of the battles
On the side of the Confederation of Independent Systems, a tactical superdroid was just one of many powerful weapons. You can add the "Dark Reaper" or "The Sinister" to this list, but in the end they were expected to lose. Darth Sidious single-handedly led the war from two sides. He chose the points of collision and the side of the winner. The entire battlefield was one chessboard in his hands. The Confederation was doomed at the time of the outbreak of hostilities.
Palpatine was supposed to strengthen power in the Galactic Council to the maximum. He represented the side of the Republic, proving his superiority. In the following raids, Anakin Skywalker and Obi-Wan Kenobi were noted for their contribution to the victory of the Republic. The complete destruction of the separatists was already in the days of Darth Vader. He personally dealt with the pawns of the future Emperor. The system of sole authority in the KNS has become a legacy for the state of Darth Sidious. The "Death Star" was developed at the time of the Clone Wars, and all the drawings passed into the power of engineers of the Galactic Empire.
