Starfleet predates the founding of the Federation by several decades, and was responsible for launching the first Human Warp 5-capable starship, the Enterprise NX-01.
Though Starfleet is comprised of many races, Humans and Vulcan, two of the four founders of the Federation (the other two being the Andorians and the Tellarites), have the most prominent roles in early episodes.
Starfleet has been shown to handle diplomatic, scientific, and military missions, although their main mandate seems to be one of peaceful exploration.
