September 15th is the anniversary of the 1820 Constitutionalist revolution in Portugal but, if you’re having trouble remembering the details, don’t worry. They don’t matter.
They don’t matter because all the revolution, the counterrevolution and a bewildering series of coups and paper constitutions and dictatorship did subsequently was confirm Chamfort’s maxim that “Only the history of free peoples merits our attention; that of men under despotisms is simply a collection of anecdotes.”
So if you’re lucky enough to live in a free country, hold tight to your heritage. Don’t let it slip away leaving you nothing but grim anecdotes.
