John Edward Lloyd was one of Wales’s most noted historians. He was educated at Aberystwyth University and Lincoln College, Oxford, where he successfully obtained a First Class degree in Honours and Classical Moderations in 1883. Two years later Lloyd was also placed in the First Class of History at Oxford. An academic career soon followed – he was appointed lecturer in History at Aberystwyth University in 1885 and Professor of History at the University College of North Wales, Bangor in 1899. John Edward Lloyd was a medieval specialist and he wrote many comprehensive papers on the early history of Wales. ‘A History of Wales: from the earliest times to the Edwardian conquest’ was published in two volumes in 1911 and is remembered as Lloyd’s great standard work; his masterpiece. It was unique in the sense that its content was compiled through a critical assessment of the sources and thorough scientific research. This book was a turning-point in the study of Welsh history and was arguably the first substantial publication to be considered by professionals as an authoritative assessment on the subject. It is no surprise therefore that some scholars have referred to John Edward Lloyd as the ‘father’ of the study of Welsh history.
