Tywysog Cymru sees The Crown tackle Prince Charles' term at Aberystwyth University and his investiture in 1969. But what does the title of this episode of the Netflix drama actually mean?
For those unfamiliar with Welsh translations (this episode is largely in Welsh by the way) we've got the answer right here.
'Tywysog Cymru' means 'Prince of Wales' - it's pretty easy to work out, really, considering the entire episode is about Charles, the Prince of Wales himself.
The episode sees Charles (Josh O'Connor) made to leave Cambridge University to study Welsh at Aberystwyth, ahead of his investiture in the July of 1969. You can read more from Josh about playing Prince Charles, in this interview here.
In the show it's seen as a measure by the government to keep the growing Welsh nationalist popularity subdued for the 'future of the union' as Prime Minister Harold Wilson (Jason Watkins) says in the show.
"Why not pull him out of Cambridge and send him to Wales for a term? We think it would be enormously helpful."
At Aberystwyth University he was tutored by Welsh nationalist lecturer, Dr Edward Millward, who is profiled here.
