History 
Commentry was home to Compagnie de Commentry-Fourchambault-Decazeville, thanks to an important coal deposit. The coal mine fueled a huge growth in population, from under 1,000 to more than 12,000, while Stéphane Mony was its CEO (1840–1884). Commentry was the first commune ever to elect a socialist mayor: Christophe Thivrier was elected 6 June 1882. The Socialist Party of France was founded in Commentry in September 1902. Economy
Commentry gave its name to a coal field over 21 square kilometres in extent, and historically had important foundries and forges. Science
