A brief popular history of the Welsh protest against the Investiture of Prince Charles in Caernarfon in 1969 (as seen in popular Netflix series The Crown). From Cymdeithas yr Iaith to the Free Wales Army, Mudiad Amddiffyn Cymru and many other groups, placards, sit-ins, paramilitary-style parades and even a bombing campaign across the country showed that many in Wales were not happy to accept an English Prince of Wales.
