Mizarian

The Mizarians are a humanoid species native to the planet Mizar II. Mizarians value peaceful non-resistance over confrontation; because of this reputation, they were conquered six times in a matter of three centuries. The Mizarians have survived these invasions by offering absolutely no resistance. They are a species known for possessing superior intelligence.

In 2380, a Borg Cube attempted to assimilate the species, but instead was thwarted by a Klingon ship and crashed to the planet surface below. (Star Trek: Invasion 101)
