The declaration of Hungarian independence was made possible by the positive mood created by the military successes of the Spring Campaign.

[1][2] Kossuth issued the declaration himself, from the Reformed Great Church of Debrecen.

The declaration accused the Habsburgs of crimes, saying The House of Habsburg-Lorraine is unexampled in the compass of its perjuries [...] Its determination to extinguish the independence of Hungary has been accompanied by a succession of criminal acts, comprising robbery, destruction of property by fire, murder, maiming [...] Humanity will shudder when reading this disgraceful page of history.

In a banquet speech before the Corporation of New York, Kossuth urged the United States to recognize Hungarian independence, saying The third object of my humble wishes, gentlemen, is the recognition of the independence of Hungary.

[...] our Declaration of Independence was not only voted unanimously in our Congress, but every county, every municipality, has solemnly declared its consent and adherence to it; so it became not the supposed, but by the whole realm positively, and sanctioned by the fundamental laws of Hungary.
