Ulmus minor Mill., the field elm, is by far the most polymorphic of the European species, although its taxonomy remains a matter of contention. Its natural range is predominantly south European, extending to Asia Minor and Iran; its northern outposts are the Baltic islands of Öland and Gotland, although it may have been introduced by humans. The tree's typical habitat is low-lying forest along the main rivers, growing in association with oak and ash, where it tolerates summer floods as well as droughts.

Maximilien de Béthune Sully, 1st Prince of Sully, Marquis of Rosny and Nogent, Count of Muret and Villebon, Viscount of Meaux was a nobleman, soldier, statesman, and counselor of King Henry IV of France. Historians emphasize Sully's role in building a strong, centralized administrative system in France using coercion and highly effective new administrative techniques. While not all of his policies were original, he used them well to revitalize France after the European Religious Wars. Most, however, were repealed by later monarchs who preferred absolute power. Historians have also studied his Neostoicism and his ideas about virtue, prudence, and discipline.
