The logical facade of Vulcans masks a history of violent, religious fanaticism

In short: Vulcans are the ultimate study in self-imposed restraint. While they appear as stoic masters of logic, their society was forged in the fires of a violent revolution. To understand their current peace, one must look back at the era of rage they worked so hard to erase.

Before the adoption of Surak's code of emotional control, Vulcans were described as dangerously raging, emotional, and war-like. They were characterized by religious fanaticism to the point that their behavior threatened the very survival of their species. This era of chaos ended around the 4th century BC when a figure named Surak introduced a system revolving around the suppression of emotions for the safety of the species. This ideological shift caused a massive schism: those who embraced Surak's logic became the modern Vulcans, while those who resisted the change became the Romulans.

Despite their reputation for coldness, Vulcans still possess and experience emotions; they simply make great efforts to keep them from controlling their behavior. Total removal of every feeling from one's psyche occurs solely for individuals reaching kolinahr's level of discipline. This internal struggle is most evident in the character of Spock, whose half-human heritage creates a constant tension between his Vulcan upbringing and human sentiment. Furthermore, Vulcan emotions are reportedly more intense than human ones, a fact highlighted by Ambassador Sarek, who warned that his unrestrained feelings could overwhelm a human during a mind-meld.

The species also possesses unique biological traits adapted to their desert planet, which has 1.4 g of gravity. They can survive without water for longer periods than humans and can go without sleep for as long as two weeks. They also possess a nictitating membrane to protect their vision from their sun. Despite their stoic reputation, kin ties can be very loving, evidenced by T'Pol's connection with her mother or Spock's link to Michael Burnham, his adopted sister.

Cultural customs further define their identity, including arranged marriages bonded in childhood and the 'Kahs-wan,' a desert initiation ordeal where children must fend for themselves. While they are vegetarians by choice, they were historically omnivores. Even their biology is distinct: they have green blood due to copper-based hemocyanin and their hearts are located on the right side of the torso. These details create a complex portrait of a species that chose logic not because they lacked feeling, but as a survival mechanism against their own nature.
