A cold planet with a short rotation located in the Corporate Sector, Ammuud was ruled by seven major clans operating under Corporate Sector Authority subcontract.
Ammuud was first colonized approximately 10,000 BBY by settlers from Thokos, and each of the seven original colony ships formed the basis of Ammuud's seven clans; the House Glayyd, Reesbon clan, Tikeris clan, Owphrin clan, Melchett clan, Almowri clan, and the Odoon clan. Appointing matriarchs called the Mors the government grew corrupt over time. An independent state for several centuries, developed without any contact with the Galactic Republic, a multi-planetary government forming in the Core Worlds of the galaxy. Forgotten by their homeworld, and the clans evolved into quarreling nation-states, continually testing each other in an endless series of savage battles. Circa 100 BBY, the clans called a truce, and formed the Code of Ammuud to govern their future conduct.
The people of Ammuud eventually constructed a large, main spaceport within a well-defended structure adjacent to a snow-capped mountain range. People of all types inhabited the surrounding city, which was composed of wood and stone buildings, slums, and open gutters. The Republic eventually made contact with the world following the blazing of the Hydian Way, when they reached Bonadan. Joining the massive government, the area of space was organized into the Corporate Sector in 490 BBY to free the Republic's lawmakers and the corporate moneymakers from their differences.
During one of his early adventures, smuggler Han Solo visited the mountain stronghold of the Mor Glayyd to collect money due him, and encountered the infamous gunman Gallandro. In 10 ABY, the New Republic, reeling from the destruction of their command base on Nespis VIII, scattered its command ships and fighter units across the galaxy. One of them, the fleet transport Vindicator carrying Luke Skywalker and his Jedi trainees, was stationed out beyond the planet Ammuud, providing cover from the Imperial Remnant.
