Criticism of the Spanish king, long targeted by separatists and left-wing anti-monarchists, increased after 2017 when he called for Spanish unity following a violent police crackdown on people trying to votes for Catalonia's independence referendum.
Tens of thousands of people from Spain's Basque Country joined hands to form a human chain running some 202 kilometres (125 miles) on Sunday to call for the right to hold a regional independence vote.
The Basque militant group is set to complete its dissolution at a peace conference in the French Basque Country a day after they released a "final declaration" recorded by a historic high-ranking ETA figure.
Senior ETA members including fugitives are expected to appear in a video declaring the end of their separatist campaign.
The meeting will take place in Cambo-les-Bains in southwest France, where the separatist group is expected to make a historic declaration that it is ending its fight in Spain's Basque Country.
