Works & Achievements
Agreement signed following the defeat at Isly, by which Morocco committed to ceasing all support for Abd el-Kader. This treaty marked the first major Moroccan concession under French colonial pressure and signaled the end of official backing for Algerian resistance.
Treaty establishing, under duress, the border between Morocco and French Algeria. This artificial frontier, which ignored local tribal realities, generated lasting tensions in the region and remained disputed well beyond the nineteenth century.
An attempt to create a regular infantry trained along European lines with the help of foreign instructors. The first outline of military modernization in modern Moroccan history, it foreshadowed the reforms that his successors would continue to pursue.
Trade agreement granting customs advantages to British merchants in Morocco. Signed under diplomatic pressure, it illustrates the economic concessions the sultan was compelled to make in order to preserve an increasingly fragile political independence.
A body of letters and negotiations with France, Spain, Great Britain, and the Ottoman Empire, preserved in Moroccan and European archives. These documents attest to an active diplomacy aimed at maintaining Sharifian sovereignty in the face of colonial ambitions.
Anecdotes
In 1832, the French painter Eugène Delacroix accompanied a French diplomatic mission to Morocco. Moulay Abd er-Rahman received him in solemn audience at Meknes, surrounded by his mounted Black Guard. This encounter inspired the famous painting *The Sultan of Morocco and His Entourage*, exhibited at the Salon of 1845, which revealed the splendor of the Sharifian court to European audiences.
On August 14, 1844, the Moroccan army was crushed by the French forces of Marshal Bugeaud on the banks of the Isly River, near Oujda. Despite the numerical superiority of his cavalry, the sultan was overwhelmed by devastating modern artillery. This humiliating defeat forced him to sign a peace treaty and officially abandon all support for Abd el-Kader.
Before the Battle of Isly, the fleet of the Prince of Joinville bombarded Tangier (August 6, 1844) and then Mogador — present-day Essaouira — from the sea. These naval bombardments, to which Morocco had no answer for lack of a war fleet, laid bare the military gulf between the Sharifian empire and Europe's industrial powers.
Aware of the technical lag in his armies, Moulay Abd er-Rahman attempted to introduce a European-style regular infantry known as the *Nizam*. Foreign instructors were recruited to train these new units, but internal resistance and a lack of resources hampered this ambitious reform, which remained unfinished until his death in 1859.
After the defeat at Isly and Abd el-Kader's surrender to the French in 1847, the sultan was compelled to accept an Algerian-Moroccan border imposed by the Treaty of Lalla Maghnia (1845). This border, drawn without regard for the nomadic tribes who freely crossed it, would remain a source of tension between Morocco and Algeria well beyond the nineteenth century.

The Sultan rode out from his palace on horseback, surrounded by his guard and his officers. His dress was simple yet his bearing commanded great majesty; he scarcely glanced at the crowd, with that air of confidence that comes from a lifetime of absolute command.
We have always wished to maintain relations of sincere friendship with France; the disputes that have arisen cannot alter our shared will for peace and trade, founded on the mutual respect of our sovereignties.
