Rom

 or Gypsy plural Roma

Any member of a people originating in northern India but now living worldwide, principally in Europe. Most speak Romany in addition to the local language. It is thought that Roma groups left India in successive migrations, reaching western Europe by the 15th century. In the 20th century they spread to North and South America and Australia. Because of their often nomadic and marginalized lives, population figures are largely guesswork; estimates in the early 21st century range from two to three million. They have often been persecuted and harassed; the Nazis killed about 400,000 Roma in extermination camps. How many Roma retain a nomadic lifestyle is unclear, but those that migrate do so at least seasonally along patterned routes that ignore national boundaries. They pursue occupations compatible with a nomadic life. In the past they were often livestock traders, tinkers, fortune-tellers, and entertainers; today they are often car mechanics, auto-body repairmen, and workers in traveling circuses and amusement parks. Confederations of 10–100 families elect chieftains for life, but their title is not heritable. Women are organized as a group within the confederation and represented by a senior woman. Modern Roma culture faces erosion from urban influences; integrated housing, economic independence, and intermarriage with non-Roma have weakened Roma law.

Rome

 Italian Roma

City (pop., 2001 prelim: 2,459,776), capital of Italy. It is situated on the Tiber River in the central part of the country. The historical site of Rome on its seven hills was occupied as early as the Bronze Age (c. 1500 BC), and the city was politically unified by the early 6th century BC. It became the capital of the Roman Empire (see Roman Republic and Empire). The Romans gradually conquered the Italian peninsula (see Etruscan), extended their dominion over the entire Mediterranean basin (see Punic Wars), and expanded their empire into continental Europe. Under Pompey the Great and Julius Caesar, Rome's influence was extended over Syria, Jerusalem, Cyprus, and Gaul. After the Battle of Actium, all Roman lands were controlled by Octavian (Augustus), the first Roman emperor. As the imperial capital, Rome became the site of magnificent public buildings, including palaces, temples, public baths, theatres, and stadiums. It reached the peak of its grandeur and ancient population during the late 1st and early 2nd centuries AD. It remained the capital of the Roman Empire until Emperor Constantine the Great dedicated Constantinople (now Istanbul) in 330. By the end of the 6th century the protection of the city was in the hands of the Roman Catholic church (see Holy Roman Empire), which achieved absolute rule only in the 15th century. The city flourished during the Renaissance and was the seat of the papacy and the Papal States. In 1870 it became the capital of a united Italy. It was transformed into a modern capital in the 1920s and '30s and is Italy's administrative, cultural, and transportation centre. See also Vatican City.
