Italy is largely homogeneous linguistically and religiously but is diverse culturally, economically, and politically. Italy has the fifth-highest population density in Europe--about 200 persons per square kilometer (490 per sq. mi.). Minority groups are small, the largest being the German-speaking people of Bolzano Province and the Slovenes around Trieste. Other groups comprise small communities of Albanian, Greek, Ladino, and French origin. Immigration has increased in recent years, however, while the Italian population is declining overall due to low birth rates. Although Roman Catholicism is the majority religion--85% of native-born citizens are nominally Catholic--all religious faiths are provided equal freedom before the law by the constitution.

Greeks settled in the southern tip of the Italian Peninsula in the eighth and seventh centuries B.C.; Etruscans, Romans, and others inhabited the central and northern mainland. The peninsula subsequently was unified under the Roman Republic. The neighboring islands came under Roman control by the third century B.C.; by the first century A.D., the Roman Empire effectively dominated the Mediterranean world. After the collapse of the Roman Empire in the West in the fifth century A.D., the peninsula and islands were subjected to a series of invasions, and political unity was lost. Italy became an oft-changing succession of small states, principalities, and kingdoms, which fought among themselves and were subject to ambitions of foreign powers. Popes of Rome ruled central Italy; rivalries between the popes and the Holy.
