Tocqueville was a member of Parliament at the time of the 1848 revolution in France, which took down Louis Philippe's monarchy and replaced him for a Republic; he was part of the committee that drafted the Republican constitution and then was Minister of Foreign Affairs for a brief time the next year. Here he tells his impressions of the whole thing.
It is always interesting to read of troubling times from a first-hand witness, but in this case there is the added incentive that Tocqueville is a man in the habit of observing and reflecting, and his judgements on a number of happenings and characters are fascinating, especially because he is outrageously candid in his opinions and very sincere as to his own conniving (obviously the "Souvenirs" were not initially intended for publication, which allows him to be less diplomatic).
His opinions in themselves are interesting because they come from a man belonging to an aristocracy which had lost all power but retained a certain influence, who hates the feeling of being under the thumb of what he feels as a crass, utilitarian, indelicate and badly educated bourgeoisie, despises a king who thinks only of the industry, describes Louis Napoleon as an adventurer too dangerous to the State to be left unchecked (trying to handle him was an interesting proposition but it ultimately fails, same as Cicero failed to handle young Octavian in a not entirely dissimilar situation), and generally thinks of his fellow politicians only in terms of how they can best be used to serve Tocqueville's purposes. I find it is to Tocqueville's credit, thinking as he does, that he is quite reconciled to the idea of having a republic he doesn't particularly like, because he can see no other viable option for the survival of the State, and does his utmost to protect the system, even though governed by people he doesn't particularly relate to and while knowing that the whole thing is doomed because of the intrinsic contradiction of a strong Parliament and a strong Presidency held by someone with barely concealed imperial ambitions.
I read this book shortly after reading Victor Hugo's "Histoire d'un crime", which also relates first-hand impressions of what happens eighteen months later, when President Louis Napoleon indeed carries out a coup against the Parliament. Victor Hugo was also a member of Parliament (though rather more to the left than Tocqueville), was already opposed to Louis Napoleon himself before the coup and, incensed at the audacity of "Napoleon le Petit", tries to lead a counter-revolution against the government by prompting the people to the barricades (ultimately this failed too, France ended up as an empire again and Victor Hugo paid for his acts with a 20-year exile). It is very interesting to compare the two as a rendering of the times from the two perspectives of a cold-blooded, thinking and rather cynical right-wing man (Tocqueville) and a very hot-blooded left-wing man of action inspired by the heroic romanticism of the era (Hugo).
