Through a study of an 'invented' royal ceremony held in Wales in 1911 and again in 1969, "Investiture: Royal Ceremony and National Identity in Wales 1911-1969" explores the problematic, contested and changing relationship between nationality, ethnicity and the state in the United Kingdom. What happens to the meaning of the British monarchy when it leaves the English centre and crosses into the Celtic periphery? How does royal ceremony become a vehicle for defining and contesting the relationship between ethnicity, nationality and the state when it takes place amongst a problematic group like the Welsh? How are internal social and cultural divisions within the periphery represented, addressed and reconciled in such ceremonial? How do these relationships and the constellations of identity that they form change over time? This study explores the ethnic margins and imperial dimensions of British national identity through the ceremonies of the Investiture of the Prince of Wales and the public reaction to them. Through the vehicle of ascribing meaning to this royal ceremony, competing parties and social groups defined alternative and often conflicting models of Welshness and its relationship to British national identity, the British state and the British Empire.
