The North Atlantic Treaty was signed on 4 April 1949 by NATO's 12 founding members. In the 75 years since, the Alliance has grown to include 32 Allies from Europe and North America. Throughout 2024, NATO Allies celebrated the Alliance's 75th anniversary - and the anniversaries of their accessions to NATO - by painting murals, playing music, sharing birthday cake and bringing NATO blue to every corner of the Alliance.
