He was the eldest son of King Nicholas I of Montenegro and Queen Milena Vukotić. During the Balkan Wars and World War I he led the Montenegrin Army with his father (the King), Janko Vukotić, and Mitar Martinović.
His reputation was undermined by announcing his renunciation on 5 March only to publicly retract this the following day, before re-affirming it the day after that. His decision was met with much dismay amongst the Montenegrin expatriate community. Prince Danilo was married to Duchess Jutta of Mecklenburg (1880–1946) the daughter of Adolf Friedrich V, Grand Duke of Mecklenburg-Strelitz, but the marriage was childless.
After his renunciation in 1921, he spent most of his life living in Nice.
Prince Danilo resurfaced in 1934 when he sued Metro-Goldwyn-Mayer for libel and collected $4,000 in a Paris court for the false depiction of him in the first version of the film The Merry Widow. In the film, "Prince Danilo of Montenegro" seduces a commoner and then rejects her because it could impoverish the royal treasury.
The film bears no relation to reality. The film was re-shot after the lawsuit.
In addition to demoting the Prince to a Captain, the date of the action was changed from 1905 to 1885, when the real Prince was a young boy.
Danilo died in Vienna (which had recently been annexed by Nazi Germany) in 1939 without issue. Danilo is famous as a one-time composer, composing the music for the Serb patriotic song of his predecessor King Nikola Onamo, "namo!, which he published in Prague.
