umber of overseas possessions. The two most traumatic
experiences in the nation's history were the Civil War (1861-65) and
the Great Depression of the 1930s. Buoyed by victories in World Wars
I and II and the end of the Cold War in 1991, the US remains the
world's most powerful nation state. The economy is marked by steady
growth, low unemployment and inflation, and rapid advances in
technology.

Uruguay
Montevideo, founded by the Spanish in 1726 as a military
stronghold, soon took advantage of its natural harbor to became an
important commercial center. Annexed by Brazil as a separate
province in 1821, Uruguay declared its independence four years later
and secured its freedom in 1828 after a three-year struggle. The
administrations of President BATLLE in the early 20th century
established widespread political, social, and economic reforms. A
violent Marxist urban guerrilla movement, the Tupamaros, launched in
the late 1960s, led Uruguay's president to agree to military control
of his administration in 1973. By yearend, the rebels had been
crushed, but the military continued to expand its hold throughout
the government. Civilian rule was not restored until 1985. Uruguay's
political and labor conditions are among the freest on the continent.

Uzbekistan
Russia conquered Uzbekistan in the late 19th century.
Stiff resistance to the Red Army after World War I was eventually
suppressed and a socialist republic set up in 1924. During the
Soviet era, intensive production of "white gold" (cotton) and grain
led to overuse of agrochemicals and the depletion of water supplies,
which have left the land poisoned and the Aral Sea and certain
rivers half dry. Independent since 1991, the country seeks to
gradually lessen its dependence on agriculture while developing its
mineral and petroleum reserves. Current concerns include terrorism
by Islamic militants, economic stagnation, and the curtailment of

Vanuatu
The British and French, who settled the New Hebrides in the
19th century, agreed in 1906 to an Anglo-French Condominium, which
administered the islands until independence in 1980.

Venezuela
Venezuela was one of three countries that emerged from the
collapse of Gran Colombia in 1830 (the others being Colombia and
Ecuador). For most of the first half of the 20th century, Venezuela
was ruled by generally benevolent mi
