Wales is a Celtic nation of the United Kingdom renowned for its dramatic landscapes, medieval castles, and vibrant culture. From the soaring peaks of Snowdonia to the rugged Pembrokeshire coastline and the charming capital city of Cardiff, Wales offers extraordinary diversity in a compact area. Welsh language, music, and traditions remain alive and celebrated, giving the country a distinct identity that sets it apart from its neighbours.
Wales has one of the longest continuous histories of any nation in Europe. The Welsh are descendants of the Celtic Britons who inhabited the island before the Roman conquest in 43 AD. After Rome's withdrawal, Welsh kingdoms flourished. Viking raids, Norman conquest (1066), and repeated wars with England shaped the medieval period. Edward I's 'Iron Ring' of castles (1277–1307) are UNESCO World Heritage Sites and stand as monuments to military architecture — and Welsh resistance. Owain Glyndŵr's revolt (1400–1415) was the last major Welsh uprising. Wales was legally incorporated into England by the Acts of Union (1536). The 19th-century coal and slate industries transformed south and north-west Wales, making Cardiff one of the world's busiest coal ports. Welsh devolution (1999) established the Senedd Cymru in Cardiff Bay, returning legislative power to Wales for the first time since 1536.
