Congrès celtique
There had been an eleven-year gap before the August 1949 Celtic Congress at Bangor, Wales where delegates included Sir Ifor Williams and Conor Maguire, Chief Justice of Ireland. Meetings have been held almost every year since then. The Celtic Congress of 1950, held at the Royal Institution of Cornwall in Truro, was a catalyst for the foundation of Mebyon Kernow the following year. The Wales branch hosted the meeting at Aberystwyth in 1960.
