- "I'm a member of the Imperial Senate on a diplomatic mission to Alderaan."
- ―Princess Leia Organa
A diplomat was someone involved in diplomacy, the art and practice of conducting negotiations between representatives of groups or states. They were studious followers of politics and law. Some were devoted to free democracy. Others, like the Separatist senators, were more interested in their own needs. Jedi Master Adi Gallia's parents were noted Corellian diplomats.
The key role of any given diplomat was to simply keep up relations with other species, planets, and systems. Since there was an amazingly vast amount of species in the galaxy, their role was a vital one.
Each sector had at least one Senator, a form of diplomat that partook in meetings with the Galactic Senate. In some cases, there may have been two or more senators from any given planet, such as with Padmé Amidala and Jar Jar Binks from Naboo.
