United Kingdom
Unlike the House of Commons, the people in the House of Lords are not elected. The people who sit in the House of Lords are called peers. Most peers are appointed by the government. There are some who are hereditary peers (who inherit their peerages from ancestors or other family members). Certain bishops in the established Church of England also attend the House of Lords. (The Church of England is the national church in England. The Church of Scotland does not have bishops, and neither Wales nor Northern Ireland has an established national church.) Together, the two houses make a bicameral legislature, in which the House of Commons has more power. In the past, the House of Lords had more power. Before the 20th century, the prime minister was often a member of the House of Lords. As the House of Lords lost its powers, as political reforms tried to improve democracy, the House of Commons became more powerful and the prime minister is now always a member of the House of Commons.
