Human Chain for Basque Self-determination, 2014
The Human Chain for Basque Self-determination, also called gure ESKU bidea (Basque words which mean "our right" and also "the way is in our hands," as a pun), was a human chain and demonstration held on 8 June 2014 in the Basque Country, claiming the Basque people's right to decide about their political status, eventually as a nation. It linked Durango (Biscay) to Iruñea (Navarre) by a human chain along 123 km.
