Presidency

According to The Book of the War, the term of "the Presidency", referring not to the Lord President themselves but to them, their High Council, and all their assorted advisors, was more common in discussion of the Homeworld's politics. This was due to the static nature of the Great Houses and lack of individual initiative on the part of most presidents. Within this terminology, the Lord President was known as the Head of the Presidency, at least until the term gained another connotation during the War. (PROSE: The Book of the War)
