Mas Amedda/Legends

In the years prior to the Battle of Naboo, Mas Amedda served as a senator in the Galactic Senate, presumably representing his homeworld of Champala. He was a member of the 'hands-off' political faction lead by Orn Free Taa, and as such, was successfully nominated by Taa to be elected to the position of Vice Chair in 33 BBY. His main duties were to provide Taa's faction with a means of control over Supreme Chancellor Finis Valorum, who had been weakened by a debacle at Eriadu and a scandal involving money laundering. The support of Valorum's policies in the Senate degenerated, which effectively paralyzed the chancellor's government. In this situation, the following year Mas Amedda presided over the motion of a Vote of No Confidence in Valorum's leadership, as requested by the Queen of Naboo.

Amedda presumably voted with his faction in support of Palpatine, and continued to serve as Vice Chair for the duration of Palpatine's term as Chancellor, remaining in office even after the declaration of the Galactic Empire.

Mas Amedda was present when then-Emperor Palpatine attacked Master Yoda with Force-lightning. He showed not the slightest sign of surprise, and left the site of battle fairly unagitatedly. This might signify either his confidence in the Emperor's combat prowess, or his indifference in the outcome of the duel. It is hard to determine how much Amedda, a covert political collaborator with Palpatine since very early in their political careers, knew about Palpatine's double life. However, his addressing of Palpatine as 'Master' probably sheds some light on this matter.

It is not known how much longer Amedda remained in office after the formation of the Empire, especially given the rise of High Human Culture. Presumably his duties were assumed by Grand Vizier Sate Pestage.
