"Quest for Empire: The Political Kingdom of God and the Council of Fifty in Mormon History." By Klaus J. Hansen. (East Lansing: Michigan State University 1967) The book is out of print and collector's copies are running about $200.00
In Quest for Empire, Klaus Hansen lays out the diabolical plan of the Mormon leaders since founder Joseph Smith, Jr. had himself crowned King of the Earth by the Council of the Fifty in 1844 not too long before his death.
Every successive leader of the Mormon Church has been also crowned "King" of the Earth. Present Mormon Leader Thomas Monson is also crowned King of the Earth.
The semi-secret Council of the Fifty (spelled backwards in early times, "ytfif "in a clumsy attempt to conceal it) was created by Joseph Smith to prepare the way for the Mormon concept of the Kingdom of God on Earth. It is and has been relentless in that pursuit.
