Spock certainly was a major part of Federation history.
But was he the most important person? Polygon writer Susana Polo thinks so as she recently wrote in her post about the half-Vulcan/half-human. Spock’s contributions to the Federation are legendary. Yes, he did help resolve the cold war between the Federation and the Klingon Empire, and he helped to reunify Vulcan and Romulus. But haven’t all the major Star Trek players had successes that prove their irreplaceable worth to the Federation? And should those successes define the importance of their place in history? Perhaps, especially in the case of one captain who sacrificed everything for the Federation.
Captain Sisko was instrumental in bringing an end to the Dominion War which was one of the deadliest conflicts in Star Trek history. Without him to lead, the war could have gone on for a lot longer and resulted in even more deaths and destruction to the galaxy. That alone makes him extremely important. Then, of course, he had to take on Gul Dukat at the fire caves on Bajor to stop the ‘Pai’Wraths from breaking free. Had he not been successful, the dark gods could have taken over everyone and every place and had plans to essentially burn the galaxy.
While Spock is certainly a major contributor to the history of the Federation, he can’t necessarily be seen at the most important.
Don’t get me wrong. I have nothing against Spock, and I think he’s one of the best characters in Star Trek. But I firmly stand behind Captain Sisko when it comes to who protected the Federation the most, and therefore, played the largest part in securing its future. What other character also negotiated with the Prophets to help save the wormhole from the Dominion fleet? Also, he wasn’t just in charge of a ship; he was in charge of an entire Quadrant.
Captain Sisko hasn’t been seen onscreen in recent years, but his contributions as a Starfleet captain are undeniable, and one would be hard pressed not to see how he was up against a wall, came out fighting, and with the help of his crew, saved the Quadrant and the Federation. That, to me, makes him the most important person in Federation history.
