Almanach royal de Westphalie: pour l’an 1812, 1813 is an official court and state directory of the Kingdom of Westphalia during the final years of its existence under Jérôme Bonaparte. Issued annually in French—the administrative language of the Napoleonic regime—the Almanach functioned as both a prestige publication and a practical reference work, comparable to other European court almanacs of the period.
The volume is organized in a hierarchical format, beginning with the royal family and court, followed by detailed listings of government ministries, administrative departments, judicial institutions, diplomatic representatives, and military commands. Each section identifies officeholders by name, rank, title, and often honors or decorations, providing a precise snapshot of the kingdom’s political and administrative elite in 1812 and 1813. The military sections are particularly useful, as they outline regimental structures, officer corps, and command arrangements during the height of Napoleonic mobilization.
Beyond its administrative function, the Almanach reflects the French-imposed bureaucratic order in the German states. It demonstrates the adoption of centralized governance, standardized offices, and a court culture modeled on Napoleonic France. The use of French language and terminology underscores the political alignment of Westphalia within Napoleon’s sphere and offers insight into how governance and identity were reshaped during this period.
For historians, the Almanach royal de Westphalie is a rich prosopographical source, allowing for the reconstruction of careers, networks, and institutional structures. Comparing the 1812 and 1813 editions can also reveal changes caused by the pressures of the Napoleonic Wars—such as shifts in military leadership, administrative turnover, and the strain placed on the state in its final phase before collapse in 1813.
