Wales lies west of England and is separated from England by the Cambrian Mountains. It is bordered on the northwest, west, and south by the Irish Sea and on the northeast and east by England. Wales is generally hilly; the Snowdon range in the northern part culminates in Mount Snowdon (3,560 ft, 1,085 m), Wales's highest peak.
Until 1999, Wales was ruled solely by the UK government and a secretary of state. In the referendum of Sept. 18, 1997, Welsh citizens voted to establish a national assembly. Wales will remain part of the UK, and the secretary of state for Wales and members of parliament from Welsh constituencies will continue to have seats in parliament. Unlike Scotland, which in 1999 voted to have its own parliament, the national assembly will not be able to legislate and raise taxes. Wales will, however, control most of its local affairs. The Welsh national assembly officially opened on July 1, 1999.
The prehistoric peoples of Wales left behind megaliths and other impressive monuments. They were followed by settlements of Celts in the region. The Romans occupied the region from the 1st to the 5th century A.D. Thereafter Angles, Saxons, and Jutes invaded the British island, but they left Wales virtually untouched. Beginning in the 8th century, the various Welsh tribes fought with their Anglo-Saxon neighbors to the east, but the Welsh were able to thwart attempted invasions. After William the Conqueror subdued England in 1066, however, his Norman armies marched into Wales in 1093 and occupied portions of it. By 1282, the English conquest of Wales was complete, and in 1284, the Statute of Rhuddlan formalized England's sovereignty over Wales. In 1301, King Edward I gave his son, who later became Edward II, the title Prince of Wales, a gesture meant to indicate the unity and relationship between the two lands. With the exception of Edward II, all subsequent British monarchs have given this title to their eldest son.
In 1400, the Welsh prince Owen Glendower led a revolt against the English, expelling them from much of Wales in just four years. By 1410, however, his rebellion was crushed. In 1485, Henry VII became king of England. A Welshman and the first in the Tudor line, Henry's reign, and those of subsequent Tudors, made English rule more palatable to the Welsh. His son, King Henry VIII, joined England and Wales under the Act of Union in 1536.
The Industrial Revolution transformed Wales and threatened the traditional livelihood of farmers and shepherds. In the 20th century, the economy of Wales was based primarily on coal production. After World War I, coal prices dropped; this, coupled with the Great Depression, fueled high unemployment rates and economic uncertainty.
In recent years, a resurgence of the Welsh language and culture has demonstrated a stronger national identity among the Welsh, and politically the country moved toward greater self-government (devolution). In 1999, with the strong support of Britain's prime minister, Tony Blair, Wales opened the Welsh national assembly, the first real self-government Wales has had in more than 600 years.
