Meibion Glyndŵr
Meibion Glyndŵr (Welsh pronunciation: [ˈməibjɔn ɡlɨnˈduːr], Sons of Glyndŵr) was a Welsh nationalist movement violently opposed to the loss of Welsh culture and language. They were formed in response to the housing crisis precipitated by large numbers of houses being bought by wealthy English people for use as holiday homes, pushing up house prices beyond the means of many locals. They were responsible for setting fire to English-owned holiday homes in Wales from 1979 to the mid-1990s.
