Introductioncardinal [Lat., = attached to and thus "belonging to" the hinge], in the Roman Catholic Church, a member of the highest body of the church. The sacred college of cardinals of the Holy Roman Church is the electoral college of the papacy. Its members are appointed by the pope. A cardinal's insignia resemble those of a bishop, except for the characteristic red, broad-brimmed, tasseled hat, which is conferred by the pope but not subsequently worn. Cardinals, the "princes of the church," are styled "Eminence."
The term cardinal was formerly applied to important clergymen of all sorts and countries, but in the Middle Ages it was restricted to the Roman province. The college of cardinals is the modern derivative of the clergy of the ancient diocese of Rome, used by the pope for advice and transaction of business. Pope Sixtus V set the maximum number of cardinals at 70, a tradition maintained for centuries until the pontificate of Pope John XXIII. Since then it has increased to well over 100, approaching twice that at times. The number number of cardinals eligible to vote in papal elections (those under 80 years old) was limited to 120 by Paul VI and John Paul II, but John Paul appointed more than that number several times. Following the lead of Pius XII, John XXIII and Paul VI promoted the international character of the college. John Paul continued to expand international representation in the college, and Europeans now account for only about half of the cardinals eligible to vote in papal elections.
