Sadjea is an colony of the Holy Germanian Empire. It is the last colony colonized by Germania. In 1900, Sadjea was an unstable state. The major Colonial Powers did not want to annex Sadjea because of the civil violence. Germania realized Sadjea needed order and protection from a stronger power. Germania also could claim it as it's last colony. So Germanian troops "liberated" Sadjea, declared it an Germanian colony, and settled it. Sadjea gained the Birkanian colony of New Birkaine in the Peace of Versailles.

Sadjea's major industries are farming, agiculture, oil mining, shipbuilding, merchant shipping, food packaging, fishing, and electronics production.
