32 nations fought in the First World War. This 32-book series looks at the seminal events surrounding the Paris peace treaties through the eyes of the key leaders involved - genuinely the Makers of the Modern World.

While Portuguese-speaking Brazil declared war on Germany, in the First World War, the rest of South America held back. In the end no other South American nation joined the fighting. But four - Bolivia, Equador, Peru and Uruguay - did break off diplomatic relations with Germany in 1917, in sympathy with US policy and with the Allies in Europe. Their reward was a place at the Paris Peace Conference table and for the first time a chance to play a role on the world stage rather than just in their own backyard.
