Commonwealth of Menk and Valakis

The Commonwealth of Menk and Valakis was an interplanetary state in the Beta Quadrant and a member state of the United Federation of Planets since 2236. 

Constituents and Society
It consisted of the planet Valakis (also known as Menk) in a single star system. The planet did not choose any of its city as the capital.

The Commonwealth included two native humanoid species, the Menk and Valakians. The number of Valakians was dwindling for centuries, gradually allowing the Menk to become the dominating culture of Valakis. The Commonwealth acceded to the Federation soon after discovering warp drive, in 2236.
