Dual monarchy

After the Imperial Republic absorbed the Kingdom of Albion in Year 42,607, this led to the rule of the local Logan dynasty which not only ruled the autonomous kingdom, but it's Kings and Queens often were elected Emperor of the Republic.

Of course, this phenomenon of dual monarchy has not always been true, but most Emperors of the the Republic in recent centuries have been members of the Logan family, being the siblings, spouses, parents, cousins, or otherwise relatives of the Albion monarchs, if not the Albion rulers themselves.

On the relatively rare occasions a non-Logan Emperor was elected during the era of the so-called Logan dynasty, it has almost always been a noble from the rival family of House Corrino.

The only elected Emperor of the Imperial Republic not belonging to either the Logan family or House Corrino during the time of the Logan dynasty has been the Asguardian Dwarf Hida Starironson, who served as Emperor from Year 43,960 to Year 43,980.

When the Council of Twelve nominated candidates for Emperor during this time, the usually nominate four or five candidates, usually three or four Logan family members and one member of House Corrino, more rarely a candidate from outside both the Logan and Corrino families being nominated. Often, the Regular Council members are forced into a second, runoff ballot when the top two vote-getters on the first ballot are both Logans. On the occasions a Logan was pitted against a Corrino on the second ballot, a Corrino Emperor was elected.
