Peerage of England
The ranks of the English peerage are, in descending order, Duke, Marquess, Earl, Viscount, and Baron. While most newer English peerages descend only in the male line, many of the older ones (particularly older baronies) can descend through females. Under English inheritance law all daughters are co-heirs, so many older English peerage titles have fallen into abeyance between various female co-heirs.
Peerages in the United Kingdom
The ranks of baron and earl date to feudal, and perhaps Anglo-Saxon, times. The ranks of duke and marquess were introduced in the 14th century, and that of viscount in the 15th century. While peerages for life were often created in the early days of the peerage, their regular creation was not provided for by Act of Parliament until the Appellate Jurisdiction Act 1876.
