Isly (1844) and the Tetouan War

By Laura Whitfield

The nineteenth century taught Morocco the cruelest lesson of the modern age: that courage without industry cannot stop an industrial empire. The Battle of Isly in 1844 and the Spanish war of 1859–60 were the two hammer blows that broke Morocco's military independence and opened the long road to the protectorate.

The first blow was French. In 1844, France — consolidating its conquest of Algeria — demanded that Morocco stop sheltering the Algerian resistance leader Abd al-Qadir. Sultan Moulay Abderrahmane refused, and the French responded with overwhelming force: the navy bombarded Tangier and Mogador (Essaouira), and on 14 August 1844 Marshal Bugeaud's expeditionary corps met the Moroccan army at the Isly river near Oujda. The Moroccans fought with traditional bravery — cavalry charges against artillery and rifle squares — and were destroyed. The Treaty of Tangier that followed humiliated the Sultan, recognized the French conquest of Algeria, and fixed a border designed in Paris.

The lesson was not learned fast enough. Morocco's makhzen remained a pre-industrial state: no conscript army, no artillery foundries, no military schools. When Spain — seeking colonial prestige after losing its American empire — provoked a war over Ceuta in 1859, the result was worse. Spanish forces under General O'Donnell landed at Ceuta, took Tetouan in February 1860 after bloody fighting in which Moroccan troops again charged modern rifles, and marched toward Tangier. Only British pressure stopped the Spanish from taking the whole northern coast.

The Treaty of Wad Ras (April 1860) was a catastrophe: Morocco paid Spain an indemnity of 100 million pesetas — twenty million dollars, an astronomical sum — ceded the enclave of Sidi Ifni, and accepted Spanish occupation of Tetouan until the debt was paid (the British advanced the money, taking Moroccan customs revenues as collateral). To pay, the Sultan borrowed from European banks at ruinous rates: the debt trap that would, within fifty years, deliver the country's finances — and then the country — to France.

Yet the defeats also planted the seeds of modern Morocco. Sultan Hassan I (1873–1894) — "the great traveler," who toured his kingdom to assert authority — attempted the first reforms: a modern army trained by European instructors, new taxes, the beginnings of a central administration. The ulama and the makhzen debated how a Muslim kingdom could adopt European techniques without becoming European. The questions raised at Isly and Tetouan — how does an old civilization survive the industrial age? — are the questions Morocco has been answering ever since, from the protectorate's reforms to the modern kingdom's industrialization.

Isly and Tetouan are remembered in Morocco not as shame but as warning: the moment the country understood that independence must be manufactured, not merely proclaimed.

The human cost of the nineteenth-century defeats is written in the Moroccan archives: the indemnity of 1860 — 100 million pesetas — was raised by squeezing the countryside, and the British loan that covered it mortgaged the customs houses of every Moroccan port to European controllers, the "Moroccan Debt" administered from Tangier. The makhzen's response, under Hassan I, was the mahalla — the Sultan's great traveling court, thousands of tents moving through the kingdom, collecting taxes and dispensing justice in person, the pre-modern state's answer to the crisis of authority. Hassan I died in 1894 on just such a tour, in the Atlas, and his death triggered the succession crisis that opened the road to Algeciras and the protectorate. The irony the historians note: the very reforms Isly demanded — a modern army, a central treasury, European instructors — were attempted, but the debt incurred to pay for the defeats starved the reforms of funds. Morocco learned the industrial lesson while chained to the financial consequences of not having learned it sooner — the cruelest pedagogy in modern history.
