A War That Named a Street
Alsace Road takes its name from the Alsace region of north-eastern France, annexed by the newly formed German Empire after the Franco-Prussian War of 1870–71. Under the Treaty of Frankfurt, signed on 10 May 1871, France was forced to cede most of Alsace and parts of Lorraine to Germany. The loss was a national humiliation, and sympathy for France ran high across Britain.
In the years that followed, streets, public houses, and even children across Britain were given names associated with the lost province. Alsace Road was laid out during the rapid residential expansion of Walworth in the 1870s and 1880s, and its name reflects this wave of popular sympathy. No formal naming record has been found, but the timing and context are strongly suggestive.
The street sits within a cluster of European place-names that reinforce the pattern. Cadiz Street, nearby, was formerly part of Trafalgar Street — a reference to the Battle of Trafalgar fought off the coast of Cádiz in 1805. Mina Road may take its name from General Francisco Espoz y Mina, a Spanish hero of the Peninsular War, or from the Plaza de Mina in Cádiz. Together, the cluster suggests a Victorian developer with an interest in European military history, or simply one following the fashion for naming streets after newsworthy places.
