In history, buried continuities are usually stronger than explosive ruptures. Even if they are continuities processed through the blender of geek nostalgia, behind which one doesn't need to rummage much to find the defense of unconfessable interests and ultranationalism. Now Donald Trump wants to return to the 19th century: commercial protectionism (multi-purpose tariffs), superpower geopolitics (peace through the threat of war, not through diplomatic multilateralism), and shattered democratic institutions (strong, personalist, autocratic political leaderships). Does the 21st century Catalan resemble the 19th century too? The political scientist Jordi Muñoz argued a few days ago for the similarity between territories where Sílvia Orriols' xenophobic Alliance has more demographic momentum and the regions where 19th-century Carlism received more electoral support towards the end of the 1800s.
