The Crown episode “Tywysog Cymru” appears in season 3. It is the sixth episode of that season and focuses on Prince Charles’s 1969 investiture as the Prince of Wales, along with his time studying Welsh at Aberystwyth University.
The Welsh title “Tywysog Cymru” translates as “Prince of Wales.” In the episode, Prime Minister Harold Wilson encourages the Queen to send Charles to Wales so he can learn the language and better understand the country before delivering his investiture speech. Charles’s teacher, Edward Millward, was a Welsh nationalist and approached the royal institution with deep skepticism.
The real investiture took place at Caernarfon Castle on 1 July 1969. The ceremony was televised and became a major public event, while the episode dramatizes the tensions between royal duty, Welsh identity, and rising nationalism. The title is therefore associated with season 3, not the later seasons covering Charles’s marriage and mature public life.
