Seiseno Tarrasa

The Seiseno was struck during the Corpus de Sang uprising of 1640, when Catalonia repudiated Philip IV and placed itself under French protection — a convulsion that opened the Guerra dels Segadors and effectively forced the Principality to issue its own emergency coinage. The Barcelona mint operated under direct instruction from the Generalitat rather than the Crown for the duration, a jurisdictional rupture with no peacetime precedent.

French recognition came at a steep price: Louis XIII was proclaimed Count of Barcelona in 1641, meaning these coins were technically issued under dual authority during their final production year.
