History Of Improvised Bertsolaritza

As Joxe Azurmendi points out,

A curious contradiction arises. On the one hand, a myth surrounding the origins of bertsolaritza has been gratuitously created, trying to date it from time immemorial; on the other, in these dizzy times where all myths are opposed with such ardour, a counter-myth, just as gratuitous as the myth it claims to combat, has arisen: that bertsolaritza in the Basque Country is a phenomenon more-or-less modern, with its origins about the beginnings of the 19th century.
