republican riots
We must not think of artists as men unconnected to political and social changes of their time. Besides their own personal involvement, they were often able to use art works as testimony of their protests or accusations. Michelangelo, for example, always sustained Florentine republic in the ideas of Savonarola (he made David for that movement), Picasso was involved in the leftist ideas of his time and so, when Franco obtained the power, the painter ordered that his Guernica should not return to Spain before the end of his dictatorship. Daumier, for a caricature of king Luis Philip, on 15 September 1831 was condemned to 6 months of jail and 500 Francs of fine.
