Kentares is a system in the Draconis March of the Federated Suns. Its world Kentares IV is known throughout the Inner Sphere as the site of the infamous Kentares Massacre.

Political Affiliation[edit]

Planetary History[edit]

Kentares' pleasant climate drew many colonists during the exodus from Terra. The world gave the locals almost every resource they needed and it became a primarily agrarian world.

Terran Hegemony[edit]

In 2431 the Hegemony Armed Forces launched an invasion of Kentares IV as a part of Director-General James McKenna's campaign to forcibly reintegrate colonies abandoned by the Demarcation Declaration back into the Terran Hegemony. The campaign ran for six months, as Kentares was defended by battle-hardened Federated Suns troops; it was a campaign in which the limitations of combat vehicles powered by Internal Combustion Engines were starkly highlighted to the HAF, prompting the development of fusion-powered combat vehicles.[3]

The Federated Suns would contest the Hegemony control of Kentares, with the 4th Avalon Hussars launching a campaign in the late 2440s to reclaim the planet. This conflict would involve the first deployment of DropShips intended to be military 'Mech transports, with the Hegemony forces deploying a number of Manatee DropShips. The appearance of the Manatees led to some initial successes for the HAF, but the Hussars learned to exploit the light armor and weapons array of the Manatee, destroying several of the DropShips along with their transported 'Mechs. Despite this, the Manatee deployment on Kentares proved the basic viability of the idea, even if heavier fighter screens would be needed.[42]

The Kentares Memorial reminds of the 52 million people killed during the Kentares Massacre

The Massacre[edit]

Main article: Kentares Massacre

All this changed during the First Succession War when House Kurita conquered large areas of the Federated Suns including Kentares. Coordinator Minoru Kurita was on the planet when he was shot by an infantryman of the 7th Crucis Lancers in August of 2796. In retaliation for this act his son Jinjiro Kurita ordered the DCMS to kill every inhabitant of the planet.

This terrible war crime, later known as the Kentares Massacre, continued for five months, during which more than 90 percent of the world's population was wiped out. It was a small compensation that, due to Jinjiro Kurita's assignment of so many regiments to the massacre and the following decline of morale in the DCMS, the Kuritan thrust into the Federated Suns collapsed.


The world itself never completely recovered despite the Federated Suns' best efforts. Various factors, including the remembrance of the massacre and the looming presence of the Draconis Combine border kept people and investors away.

In 2854 the Combine attacked Kentares IV again as prelude for Coordinator Miyogi Kurita's Marathon Offensive, but were repulsed by troops of Prime Marshal Peter Davion.[43]

FedCom Civil War[edit]

Some of the first clashes of the FedCom Civil War took place on Kentares IV whose duke Eric Dresari publicly denounced Archon Katherine Steiner-Davion as a despot and usurper inciting demonstrations among the people of Kentares against her rule. Therefore she ordered the 5th Donegal Guards to take control of the planet. The situation escalated and culminated in the execution of Duke Dresari and his family. The surviving family members led a guerrilla war to regain control of the world.[44]

Kentares was also a target of the DCMS reprisal attacks for the Draconis March invasion of Kurita space. On January 23 of 3065 the 3rd Benjamin Regulars landed on the planet but the local Militia held off the Regulars until the arrival of the Tenth Lyran Guards, who were due to pass through the system, defeated the invaders.

Population Data[edit]


Planetary Rulers[edit]


Kentares IV is a temperate and fertile world with plenty of common ores and other natural resources and almost ninety percent of the surface covered by water. But since the devastation of the First Succession War much of the planet's land mass has been covered by ruined cities and factories, which were never rebuilt.
