Continuation War

The Continuation War is the name given to the many border incidents and skirmishes between the Ur-Han Empire and the Terran Federal Republic between the First Contact War and the Great War. Although it theoretically stretches from 2356 to 2636, it reached its peak in intensity from 2545 to 2567, a period during which over a hundred military vessels, including seven capital ships, were destroyed in border incidents.
The various treaties signed between the Terran Republic and other galactic nations, including the Ur-Han, in the wake of the First Contact War in 2348 made Terran space off-limits for all alien vessels. However, as early as 2356 the Ur-Han encroached on Terran space with several exploration vessels. This caused the Terrans to commit to a successful military response. Until the early 2500s, the Terrans respected Ur-Han territorial integrity, whilst the Ur-Han regularly encroached on Terran space. This resulted in several minor space battles, most of which were indecisive and in Terran space. Starting in the 2500s, the Terrans became much more aggressive and began testing the Ur-Han themselves. This was the primary cause behind the tension peak in the mid-2500s.
The Continuation War is considered to have ended in 2629 with the Battle of Carybdis, in which a significant Terran force penetrated into Ur-Han territory prior to the entry into the Great War of the Federation. This allowed the Federation to test its military capabilities in real conditions before committing to the war. The operation, named Operation Malicious Intent, was a direct result of ALEPH Recommendation No. 06101 published a year earlier, which implicitly encouraged such a test.
