Muñagorriren bertsoak
Muñagorriren bertsoak (Basque for 'Muñagorri's bertsos') are a set of written bertsos (extemporaneous poems in Basque) written and published in Gipuzkoa (Basque Country, Spain) in 1838 during the last stage of the First Carlist War. During the war various bertso leaflets were published, promoting various factions, with some enjoying wide circulation and influence over public opinion across Basque language areas, the main Carlist stronghold.
