The city council of Hendaia (Lapurdi) held a one-day colloquium last Friday, October 28, to celebrate the contribution of Portuguese immigrants to society in Iparralde and beyond. It was timed to coincide with the 100th anniversary of a Franco-Portuguese agreement in 1916 that helped facilitate Portuguese emigration to the French Republic, for which Hendaia was often the first point of arrival. An exhibition titled “Sala de Espera” (Waiting Room), featuring images of newly arrived Portuguese immigrants, was held to coincide with the colloquium.

Between 1886 and 1966, Portugal lost more people to emigration than any West European country except Ireland. As regards Basque-Portuguese links, in Iparralde, there is an important Portuguese settlement in Baiona and people of Portuguese origin are estimated to make up 1.5% of the total population of France as a whole. In Hegoalde, Portuguese settled in both Greater Bilbao and Ermua, Bizkaia, as well as in the fishing towns of the Bizkaian coast and in northern Nafarroa.
One well-known Basque cultural figure of Portuguese extraction is the bertsolari (oral improviser) Xabier Silveira, from Lesaka, Nafarroa. Check out the interview with him (in Basque) above.
Interestingly, two(well, one certainly, and another possibly) key figures in modern Portuguese history were of Basque descent: Manuel de Arriaga (1840-1917), the first elected president of the First Portuguese Republic; and, conceivably–Salazar being a recognized Basque surname–António de Oliveira Salazar (1889-1970), the authoritarian ruler of Portugal from 1932 to 1968.
