The framers of the US Constitution were influenced by the Constitution of the Republic of the United Provinces, as Federalist No. 20, by James Madison, shows. Such influence appears, however, to have been of a negative nature, as Madison describes the Dutch confederacy as exhibiting "Imbecility in the government; discord among the provinces; foreign influence and indignities; a precarious existence in peace, and peculiar calamities from war." Apart from this, the American Declaration of Independence is similar to the Act of Abjuration, essentially the declaration of independence of the United Provinces, but concrete evidence that the former directly influenced the latter is absent.
