The 1634 Instrument of Government, Sweden's first written constitution in the modern sense, stipulated that the King must have a council, but he was free to choose whomever he might find suitable for the job, as long as they were of Swedish birth. At the introduction of absolutism, Charles XI had the equivalent organ named as Royal Council (). In the Age of Liberty, the medieval name was reused, but after the bloodless revolution of Gustav III, the old organ was practically abolished.
