Council of Terra
Created by the Emperor shortly after the Ullanor Crusade, the Council was created as the governing body of the Imperium whilst the Emperor worked in the vaults of his palace: to attend to matters of state and would aim to create and uphold Imperial Law throughout the newly conquered Imperium, including the controversial Imperial Tithe. The council had no military authority, which instead fell to the War Council under Warmaster Horus.

The Council of Terra attracted controversy during its time; from its inception, the Primarchs were deeply unhappy about being denied a place on the Council, after their position on the War Council which had been ruling the Imperium for the majority of the Great Crusade. This contributed to the feelings of abandonment in the Imperial military.
The Imperial Tithe faced staunch opposition from the Warmaster himself, who felt it would cause unrest and even rebellion in some newly compliant or unstable areas of the Imperium.
The Council was again beset by controversy during the Horus Heresy when Fabricator-General Kane and Mechanicum ambassador Vethorel attempted to give the loyalist Mechanicus a formal seat on the council. Many thought of this as a Mechanicus power-grab, but after a show of force by the Legio Ignatum and a threat by the Collegia Titanica to abandon Terra if their demands weren't meant, the Council of Terra relented.
