In the real world:
Aleksandr Kerensky, (born April 22, 1881, died June 11, 1970) a socialist in Russia, was well known for his oratory skill and popularity among the general public.
When the Russian Revolution of 1905 caused the creation of the Duma, Kerensky was able to attain a position in the fourth Duma, in 1912. He gained a reputation as an eloquent, dynamic politician of the moderate left.
In the aftermath of the Russian February Revolution of 1917 he was appointed the leader of the provisional government, and conducted an unsuccessful offensive towards the end of World War I. This and other actions dramatically lowered his public status, and when the Bolshevik Revolution occured, he was forced to flee the country. He spent the rest of his life fighting the Soviet regime, and eventually moved to the United States, where he died in 1970.

It was his dream of someday returning to conquer the Inner Sphere and reunite it under one rulership. Upon his death, his son, Nicholas Kerensky created The Clans in a second exodus.
