relief, in sculpture, three-dimensional projection from a flat background. In alto-relievo, or high relief, the protrusion is great; basso-relievo, or bas-relief, protrudes only slightly; and mezzo-relievo is intermediate between the two. Ancient Egyptians and Etruscans also used cavo relievo, intaglio, or sunken relief, in which the design is incised deeper than the background. High relief, although also used in ancient times, reached its climax in the baroque period. Bas-relief is commonly employed on coins and on medals.

United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA), agency of the United Nations, with headquarters in Amman, Jordan. Established in 1949, it replaced the United Nations Relief for Palestine Refugees in 1950 as the major UN agency dealing with Palestine refugees. By 2003 more than 4 million refugees and their descendents who had been displaced by the various Arab-Israeli Wars were registered with UNRWA, more than 1.3 million of them in UNWRA refugee camps. Originally the agency was charged with the care of the refugees until they could be repatriated, compensated, or resettled; UNRWA has, in fact, found itself faced with the job of housing, feeding, and educating people for long periods of time in Lebanon, Syria, Jordan, the West Bank, and the Gaza Strip. During this period, it has had the difficult task of dealing with the competing interests of Israel, the Arab states, and the Palestinian movement.

United Nations Relief and Rehabilitation Administration (UNRRA), organization founded (1943) during World War II to give aid to areas liberated from the Axis powers. There were finally 52 participating countries, each of which contributed funds amounting to 2% of its national income in 1943. A sum of nearly $4 billion was expended on various types of emergency aid, including distribution of food and medicine and restoration of public services and of agriculture and industry. China, Czechoslovakia, Greece, Italy, Poland, the Ukrainian SSR, and Yugoslavia were the chief beneficiaries. UNRRA returned some 7 million displaced persons to their countries of origin and provided camps for about 1 million refugees unwilling to be repatriated. More than half the funds were provided by the United States, and the three directors general—Herbert H. Lehman, Fiorello La Guardia, and Gen. Lowell Rooks—were American. UNRRA discontinued its operations in Europe on June 30, 1947. Its remaining work, chiefly in China, ended on Mar. 31, 1949. The functions of UNRRA were transferred to other UN agencies, chiefly the International Refugee Organization, the Food and Agriculture Organization, and the United Nations Children's Fund.

or relief printing or typographic printing

In commercial printing, process by which many copies are produced by repeated direct impression of an inked, raised surface against sheets or a continuous roll of paper. Letterpress is the oldest traditional printing technique, the only important one from the time of Johannes Gutenberg (circa 1450) until lithography (late 18th century) and especially offset printing (early 20th century). The ink-bearing surface for a page of text was originally assembled letter by letter and line by line. The Monotype and Linotype were the first keyboard-activated typesetting machines. Letterpress can produce high-quality work at high speed, but requires much time to prepare and adjust the press. For the sake of speed, newspapers are now printed by the offset process.

Public or private aid to people in economic need because of natural disasters, wars, economic upheaval, chronic unemployment, or other conditions that prevent self-sufficiency. A distinction may be drawn between relief targeting upheavals and natural disasters and relief of chronic social conditions, now usually referred to as welfare. In 17th-century China the government maintained ever-normal granaries for use in the event of famine. Through the 19th century, disaster relief in Europe consisted largely of emergency grants of food, clothing, and medical care through hastily organized local committees. In the 20th century, disaster relief became one of the chief activities of the International Red Cross and other international agencies. Assistance to the needy from public funds has traditionally been strictly limited; in England, the Poor Law Reform Act of 1834 required people able to work to enter a workhouse in order to receive public assistance. The U.S. government responded to the Great Depression with the New Deal, which emphasized work relief programs such as the Works Progress Administration. In the later 20th century, the work requirement was abandoned in most countries, and the needy received direct cash payments, though in the U.S. the movement for welfare reform resulted in the passage in 1996 of “workfare” laws cutting off relief for most able-bodied welfare recipients who failed to find a job or perform community service.
