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.
Lord
The upper house of the Parliament of the United Kingdom is the House of Lords, which is an abbreviation of the full title, The Right Honourable the Lords Spiritual and Temporal in Parliament Assembled. The Lords Temporal are the people who are entitled to receive writs of summons to attend the House of Lords in right of a peerage. The Lords Spiritual are the Archbishops of Canterbury and York, the Bishops of London, Winchester and Durham, and the twenty-one longest-serving bishops of the Church of England from among the other bishops, who are all entitled to receive writs of summons in right of their bishoprics or archbishoprics.
