Parliament met about twice a year and lasted from two weeks to several months. There was a well-defined group of about fifty barons and a few spiritual peers who were always summoned to Parliament and who composed a House of Lords. "Peer" now meant a member of the House of Lords. All peers had the right to approach the king with advice. The baron peers reasoned that the custom of regular attendance was a right that should be inherited by the eldest son, or by a female heir, if there were no male heirs. However, the theory of nobility by blood as conveying political privilege had no legal recognition. No female could attend Parliament; the husband of a baroness attended Parliament in her stead. Edward III and Richard II created new peers with various titles of dignity, such as duke and marquess, which were above barons and earls. The dukes and marquesses were identified with a territorial designation such as an English county or county town. Whenever a Parliament was assembled the commons were present. The commons was composed of representatives from 100 boroughs and 37 counties. Each new Parliament required an election of representatives. The members of the commons were generally the most prominent and powerful economic and political figures of the county and were repeatedly reelected. The electors were usually influenced by the sheriff or a powerful lord who suggested suitable men. The wealthy merchants typically represented the boroughs and paid much of the taxes. Under Edward III, the commons took a leading part in the granting of taxes and the presentation of petitions and became a permanent and distinct body, the House of Commons, with a spokesman or "speaker", chosen by the Crown, and a clerk. The speaker came to be an intermediary between the Commons and the king and between the Commons and the Lords. A clerk of Parliament registered its acts and sat with the Lords. A clerk of the Crown superintended the issue of writs and the receipt of the returns and attested the signature of the king on statutes. It became a regular practice for the Chancellor to open Parliament with an opportunity to present petitions after his opening speech. The king then referred them to certain peers and justices, who decided to which court, or Parliament, they should be sent. During the 1300s, the number of barons going to Parliament gradually decreased.
