The Romanovs: Autocrats of All the Russias book by W. Bruce Lincoln 

For three centuries--beginning with the accession of Mikhail Feodorovich Romanov in 1613--the Romanov Dynasty ruled Russia.  Its reign ended with the execution of Nicholas II and Alexandra in the early 20th century.  Noted Russian scholar W. Bruce Lincoln has brilliantly portrayed the achievement, significance and high drama of the Dynasty as no previous book has done.  His use of rare archival materials has allowed him to present a portrait of the Romanovs based on their own writings and those of the men and women who knew them.
