Until recently, how did an individual become a member of the house of lords in britain?

Unlike the elected House of Commons, most new members of the House of Lords are appointed. Membership of the House of Lords is made up of Lords Spiritual and Lords Temporal. There are currently 26 Lords Spiritual who sit in the Lords by virtue of their ecclesiastical role in the established Church of England. The Lords Temporal make up the rest of the membership; of these, the majority are life peers who are appointed by the Monarch on the advice of the Prime Minister, or on the advice of the House of Lords Appointments Commission.
