North Atlantic Treaty
treaty that forms the legal basis of, and is implemented by, the NATO
The North Atlantic Treaty, also known as the Washington Treaty, forms the legal basis of, and is implemented by, the North Atlantic Treaty Organization (NATO). The treaty was signed in Washington, D.C., on 4 April 1949.
Background
The treaty was signed in Washington, D.C., on 4 April 1949 by a committee which was chaired by US diplomat Theodore Achilles. Earlier secret talks had been held at the Pentagon between 22 March and 1 April 1948, of which Achilles said:
The talks lasted about two weeks and by the time they finished, it had been secretly agreed that there would be a treaty, and I had a draft of one in the bottom drawer of my safe. It was never shown to anyone except Jack [Hickerson]. I wish I had kept it, but when I left the Department in 1950, I dutifully left it in the safe and I have never been able to trace it in the archives. It drew heavily on the Rio Treaty, and a bit of the Brussels Treaty, which had not yet been signed, but of which we were being kept heavily supplied with drafts. The eventual North Atlantic Treaty had the general form, and a good bit of the language of my first draft, but with a number of important differences.
According to Achilles, another important author of the treaty was John D. Hickerson:
More than any human being Jack was responsible for the nature, content, and form of the Treaty...It was a one-man Hickerson treaty.
As a fundamental component of NATO, the North Atlantic Treaty is a product of the US' desire to avoid overextension at the end of World War II, and consequently pursue multilateralism in Europe.

Why this record matters
“North Atlantic Treaty” is worth following because a concise public description often conceals a longer documentary argument. Here, North, Atlantic and Treaty provides the most credible route into that argument.
Contemporary correspondence, administrative files and participant testimony can test how later narratives organized the event or institution. The source revision retrieved here is dated Sep 19, 2026. The linked authority identifier is Q877399. VIAF identifies the subject as 180026678. The Library of Congress control number is no92010826. 3 of 5 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1949, 1948 and 1950.
Official terminology may obscure informal participation, dissent or communities documented only indirectly. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
