The Clan Invasion (known to the Clans as Operation Revival) refers to the massive Clan invasion of the Inner Sphere, commencing with the arrival of Clans Jade Falcon, Wolf, Ghost Bear, and Smoke Jaguar in the near, coreward Periphery (The Rift and The Draconian Drift) in August, 3049. The Clan Invasion would continue for two and a half years, and increase in scope to include three more Invading Clans, but would end with the the Battle of Tukayyid in June, 3052.
Following the death of ilKhan Leo Showers over Radstadt in 3050, "reserve" Clans Steel Viper and Nova Cat were added ostensibly to "aid" the efforts of Clans Jade Falcon and Smoke Jaguar, while a seventh Clan, Clan Diamond Shark, did not mobilize in time to "aid" Clan Ghost Bear. However, the additions of these reserve Clans were actually meant to hinder the progress by Clan Wolf's rivals, a machination by newly-elected ilKhan Ulric Kerensky of Clan Wolf. In fact, Clans Steel Viper and Nova Cat were intentionally assigned to invasion corridors already assigned to bitter rivals.
Operation Revival was intended to be the great return of General Kerensky's heirs. Ostensibly, the Clans intended to free the people of the Inner Sphere from the greed and corruption of the constantly warring Successor States, and re-create the great Star League. As such, the Clan Invaders focused their attention and their campaigns almost exclusively on units pledged to the Lords of the Great Houses. Only on rare occasions were neutral forces engaged, specifically the Com Guard garrisons. Though ComStar facilities were present on many of the planets conquered during Operation Revival, the Com Guards were ordered to remain neutral - the new Clan Invaders would simply be a different lord to whom ComStar could provide communication services. In an unlikely twist, these neutral Com Guards became the military which stopped the Clan Invasion.
In another machination by ilKhan Ulric, the Clans "revealed" the ultimate goal of the Clan Invasion to ComStar in 3051 - Terra, ComStar's home. The rationale behind the Terran conquest was simple - the Clan capable of successfully conquering mankind's home world would become the ilClan, the Clan which would guide/control the creation of the new Star League. IlKhan Ulric (a Warden) gambled that ComStar would not stand idly while Terra was conquered. While the less sophisticated armies of the Successor Lords could not stop the Clans for some time, Ulric hoped either the more sophisticated Com Guards would halt the Clan invasion (or ensure Clan Wolf would become the ilClan). In either eventuality, Ulric's Warden stance would become ascendant.
IlKhan Ulric Kerensky's gamble worked. His "revelation" prompted Precentor Martial Anastasius Focht to muster the Com Guard in defense of a proxy world - the Com Guards would defend a pair of objectives against each Clan on Tukayyid, a small "backwater" world in the Free Rasalhague Republic. Should the Com Guard fail, ComStar offered to surrender Terra rather than fight. After a month of combat, ComStar emerged victorious, and the ensuing Truce of Tukayyid, signed shortly thereafter between ilKhan Ulric Kerensky and ComStar Precentor Martial Anastasius Focht, stipulating the Clan Invasion could not commence again for 15 years.
Had the Com Guards lost the Battle of Tukayyid, one can only speculate whether or not ComStar would have actually conceded Terra.
