absentia on March 29, 1764, they were defended by Voltaire, and eventually exonerated in 1771. The outbreak of the French Revolution was generally welcomed in Castres, particularly among the local Protestant merchants and entrepreneurs, but the majority of the population remained moderate during the whole period. In 1793 for instance, Protestant pastor Alba La Source, Castres' representative at the Convention in Paris, opposed the deportation of "non-juror" Catholic priests to French Guiana, where death in the horrid jungle was certain (see Civil Constitution of the Clergy). "Non-juror" priests were by far the majority in the region of Castres. Accused of being a moderate, Alba La Source was guillotined in October 1793. Suspected of being lukewarm toward the revolution, Castres was duly chastised. The bishopric which had been established by Pope John XXII in 1317 was abolished, Castres later becoming part of the bishopric of Albi. Capital of the of Tarn in 1790, the town was downgraded to capital of an arrondissement in 1797, Albi being made the capital of the . Despite these setbacks, in the 19th century the economy of Castres developed greatly, and the town grew outside of its old medieval center. As early as 1815, the first mechanized wool mill was set up in town. Originally specialized in luxury cloth, the Castres textile industry then turned toward more ordinary types of cloth, whose markets were considerably larger. Around 1860, there were 50 wool mills in town, employing 3,000 people. In the end of the 19th century, mechanical engineering industries appeared beside the textile industry, which led to Castres becoming a major arsenal for the French army during the First World War. Castres was linked to the French railway network in 1865. At the end of the 19th century, Castres was the largest town in the of Tarn, with 5,000 more inhabitants than Albi. However, in the 20th century the town entered a new period of decline. Although Castres emerged from the two world wars unscathed, no military operations or combats taking place in southwest France, the local economy has been hard hit by change. Like so many towns and cities of Europe which had benefited most from the Industrial Revolution, Castres is experiencing a difficult restructuring of its industrial base. Textile has particularly suffered. Castres is also crippled by its geographical location, isolated in a dead end at the foot of the Massif Central mountains, away from
