I figured this would be an appropriate day to ask this. So the various rebellions of the Irish and Scots against the English are fairly well known, but there seem to be no such events regarding the Welsh, at least not that are widely known. I know the Welsh and English alignment goes back a lot further than that with the Scots or Irish, but it seems hard to imagine there was never a large scale Welsh independence movement. So, was there ever any, and do the Welsh have their own versions of William Wallace and Wolfe Tone?
I search the faq and didn't really seem to find anything there.
Never heard of Owain Glyndŵr? There were certainly heroes and villains in Welsh history against the steadily increasing pressure of English overlordship of Wales, the difficulty is identifying quite to what extent this authority was recognised and thus what a rebellion is. So instead of me going into the minutia of Anglo-Welsh history in the twelfth- and early-to-mid thirteenth-centuries let's take post-1283/4 as our starting point.
The Welsh were suprisingly tractable in the fourteenth-century. There were a few small-scale violent attacks on the English but they never gained significant traction. So why, in stark contrast to the tumultous Welsh of the twelfth- and thirteenth-centuries, were the Welsh unable to motivate a pan-Welsh movement? Here's the gist.
The twelfth- and thirteenth-centuries had witnessed a series of succession crises which had resulted in the Princes of Gwynedd becoming the only really significant force against English hegemony in Wales. The Conquest had resulted in Llywelyn ap Gruffudd and his younger brother Dafydd both dying and there was really no one with the authority or general support to replace them.
This was an unprecedented state of affairs and it was the policies of the successive Edwards which really cemented English control over Wales, and managed to do so with only relatively small-scale resistance. The English crown assumed direct control of Gwynedd and engaged in an immense castle-building policy while inserting their own governors of the region. Almost every native ruling dynasty, except the fractured kingdom of Powys, had been destroyed and the English crown exacerbated the atomisation of native power by bluntly interpreting the manner in which Welsh territories were partibly inherited. Furthermore the Marches were now inhabited by some of the most powerful earls of England. There really wasn't much willpower or wherewithal to pose a notable threat to English rule.
Owain Glyndwr led the last major Welsh uprising from 1400 to 1415. At the time there was definitely a current of Welsh nationalism, the previous king Richard II had supported and rewarded his Welsh followers in an attempt to build a power base in Wales. When Henry Bolingbroke unseated Richard II in 1399 the Welsh nobles lost influence (similar to how Scots lost influence with the rise of Labour, if you're looking for a parallel).
The rebellion itself became so widespread that the French even signed a treaty promising formal aid. Yet eventually Henry of Monmouth (the young Henry V) slowly strangled the resistance through an economic blockade with the remaining English castles on the coast. When Henry became king he granted royal pardons to the rebellion's leaders, and the rebellion slowly died out. That's the short of it.
