Forty years on from the Emperor Agustín episode (see preceding post), México experienced a brief imperial phase for the second time. The Second Méxican empire differed from the first in being the creation of an externally-imposed political intervention. Born out of the ambitions, dreams and adventurist tendencies of the French emperor Napoleon III, the foreign intervention resulted in a hand-picked member of the Austro-Hungarian Habsburg dynasty being elevated to a “prefabricated throne” in México [Hanna, Kathryn Abbey. “The Roles of the South in the French Intervention in Mexico.” The Journal of Southern History 20, no. 1 (1954): 3-21. Accessed November 17, 2020. doi:10.2307/2954576.].
The trigger that set off the chain of events which resulted in an otherwise undistinguished Austrian archduke sitting atop a empire in faraway México was a economic crisis plaguing the Second Méxican republic in 1861. The Juarez government owed huge sums of money to foreign creditors—in particularly to France but also to other European states—which it was either unable or unwilling to repay, eventually the regime reneged on its debts. France’s Napoleon III entered into a conspiracy with México’s rich landowning class, to subvert the Juarez regime. With back-up from Britain and Spain (also creditors of the regime), the French landed a force at the port of Veracruz and demanded that Méxican government meet its financial obligations to Europe. After an initial military setback in the Battle of Puebla※, the French army eventually captured México City. The French military intervention further inflamed a civil war already in train between the conservative and liberal forces of México [‘The Emperor Maximilian arrives in Mexico City’, (Richard Cavendish), History Today, 06-Jun-2014, www.historytoday.com].
Napoleon’s empire of opportunism
Napoleon’s foray into México was not just about the recovery of international debts, some historians contend that it had a longer strategic intent, a grandiose plan to fuel the emperor’s imperialistic designs, known as la Grande Pensée (lit: “the big thought”). Having established a protectorate over the country Napoleon’s immediate objective was to create a buffer against US expansionism, which he thought could be realised by turning México into a pliant imperial ally…amounting to the creation of “a new order” in the region , one to Napoleon’s liking. This view purports that the French emperor sought to forge a “Latin, Catholic bloc” to counter any likely further US encroachment on the central and southern parts of the continent (see more on this in Footnote)◇ [Michele Cunningham, ‘México and the Foreign Policy of Napoleon III’, (Unpublished PhD thesis, University of Adelaide, December 1996]. The timing had been right, all of America’s energies were directed towards the civil war renting the union asunder, preventing Washington from taking a robust response to the European incursion in its sphere of influence⌽.
Emperor Maximilian I
Maximilian’s reluctance to play an obliging puppet role
To head the imperial construct, Ferdinand Maximilian, younger brother of the Austro-Hungarian Emperor (Franz Josef) was chosen. Maximilian was initially loathe to take on the job, he only did so after encouragement from his ambitious wife (Carlota) and after some deception on the part of the French (a phoney plebiscite was rigged to convey the impression that the Méxican people were willing to accept an Imperio Mexicano with Maximilian as emperor). Maximilian eventually warmed to the imperial role but he proved less amenable to the conservative program espoused by his backers than they had anticipated. Seeing himself as the protector of the peasantry, Maximilian endorsed wide-reaching reforms (including abolition of serfdom and child labour) and refused to restore the powerful Catholic Church to the privileged position it held prior to Juarez’s attack on its assets (Cavendish)⌑. The loss of Catholic hierarchy support didn’t help Maximilian’s prospects of surviving when things got tight politically for him in México later on.

Confederate exile plan
Maximilian’s empire, even with its heavy reliance on French support, struggled to bend all of the internal opposition to its rule⦿. Maximilian and his French backers duly forged alliances with the American South, Confederate generals Magruder and Preston were appointed envoys to México City. The door to México was opened to Confederates…settler schemes, the brainchild of southern oceanography pioneer Matthew F Maury, were launched (New Virginia Colony/Carlota Colony) to encourage postwar migration (asylum) south of the border. Maury’s colonisation scheme was intended to bring 200,000 southerners to Méxican plantations with former slaves as ‘apprentices’, however the plan never really took off. México’s long-standing ban on slavery was a further disincentive for prospective Confederate settlers (Hanna).
French end-game
As things transpired Napoleon (and Maximilian) gambled on the wrong side in the American Civil War. The Union’s emergence from the civil war triumphant was lethal for French ambitions in México, Washington was now free to turn its attention to the foreign interloper. Invoking the Monroe Doctrine of Manifest Destiny, the US “hard-balled” France into removing its troops from México. Other urgencies closer to home were also a factor in Napoleon‘s exit from México – primarily the menace of a rising Prussia. The French departure also sealed the fate of the foreign emperor they had placed on the throne. In 1867 with dwindling support for the Méxican empire, Maximilian was comprehensively defeated by the republican forces, captured and like his monarchical Méxican predecessor Agustín I, executed by firing squad.

Footnote: A rationale for French imperial reach into México and l’Amérique latine
At the time of Napoleon’s Méxican adventurism there was a widespread undercurrent of ”Pan-Latinism” in the air. The Napoleonic foreign policy that propelled France into the midst of an internal conflict in México has its rationale in the thinking of political economist of the day, Michel Chevalier. His influential ideas about Pan-Latinism struck a particular chord in France. Chevalier developed the idea that France (as leader of the Latin language countries) had a special hegemonic role to fulfil among les races Latines (the “Latin races”(sic)) vis-a-vís the Anglo-Saxon world. In the New World this manifested itself in the idea of France taking the lead in Hispanic America as a bulwark against the US expansionist juggernaut. Specifically, this meant France intervening in México to stabilise the unstable Méxican government—providing “a strong barrier on the Rio Grande to impede the march of Anglo-Saxonism”—and thus resisting Yankee territorial expansion which would undermine the solidarity of Catholic l’Amérique latine❂. And, as alluded to above, for Napoleon of course, the structure of empire was deemed the best framework to glue the various parts of the territorial entity together. A bonus incentive for France to establish a foothold in the Americas would be a chance to share in the continent’s vast riches◇[‘Pan-latinism, French intervention in México (1861-1867) and The Genesis of the idea of Latin America’, (John Leddy Phelan), (reproduced in Historical Digital), www.historicas.unam.mx].

⦿ Emperor Maximilian was probably aware of the downside of over-association with France – French diplomats sent to México City had an unfortunate tendency to make zero effort to disguise their distain for Méxicans, engendering an understandable reciprocal feeling of antipathy on the Méxicans’ part [Barker, Nancy N. “Monarchy in Mexico: Harebrained Scheme or Well-considered Prospect?” The Journal of Modern History 48, no. 1 (1976): 51-68.
