On 25 March 1941, Yugoslavia signed the Tripartite Pact with the Axis powers. The agreement was reached after months of negotiations between Germany and Yugoslavia and was signed at the Belvedere in Vienna by Joachim von Ribbentrop, German foreign minister, and Dragiša Cvetković, Yugoslav Prime Minister. Pursuant to the alliance, the parties agreed that the Axis powers would respect Yugoslav sovereignty and territorial integrity, including the Axis refraining from seeking permission to transport troops through Yugoslavia or requesting any military assistance.
