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.
Hereditary peer
The peerage has traditionally been associated with high gentry, the British nobility, and in recent times, the Conservative Party. Only a tiny proportion of wealthy people are peers, but the peerage includes a few of the very wealthiest, such as Hugh Grosvenor (the Duke of Westminster) and Lord Salisbury of Hatfield House. Most of the largest stately homes belong to the National Trust due to forms of estate tax. A few peers own one or more of England's largest estates passed down through inheritance, particularly those with medieval roots: until the late 19th century the dominant English and Scottish land division on death was primogeniture.
