Juliana menikah dengan Bernhard dari Lippe Biesterfeld, seorang bangsawan Jerman, pada tanggal 7 Januari 1937 dan mendapatkan empat anak Beatrix (1938), Irene (1939), Putri Margriet (1943), dan Marijke (1947) yang namanya kemudian diganti menjadi Christina.Ratu Juliana naik takhta menggantikan ibunya, Ratu Wilhelmina, antara tahun 1947 – 1948. Pada 27 Desember 1949, ialah yang secara resmi menyerahkan kedaulatan Hindia Belanda kepada ketua delegasi Indonesia, Mohammad Hatta, dalam pertemuan di Istana Dam, Amsterdam. Rakyat Belanda menyukainya karena ia tidak terlalu menjunjung formalitas. Putrinya, Beatrix, malah dikenal lebih formal, seperti ayahnya, Pangeran Bernhard.
Ratu Juliana pernah ke Indonesia pada tahun 1972 sambil membawa "oleh-oleh", antara lain naskah manuskrip Kakawin Nagarakretagama. Naskah lontar ini berasal dari Lombok dan sampai ke Belanda karena dijarah oleh KNIL pada tahun 1894, sewaktu tentara Belanda menaklukkan Lombok. Meski telah mengundurkan diri dari politik sejak tahun 1980, ia masih aktif di bidang sosial sampai tahun 1995. Dialah Ratu Belanda yang akhirnya mengakui kedaulatan negara Indonesia setelah pertemuannya dengan Mohammad Hatta dalam penyelesaian Diplomasi di Konferensi Meja Bundar di Den Haag, pada tanggal 23 Agustus sampai dengan 2 November 1949.
Juliana (Dutch pronunciation: [ˌjyliˈjaːnaː], Juliana Louise Emma Marie Wilhelmina; 30 April 1909 – 20 March 2004) was Queen of the Kingdom of the Netherlands between 1948 and 1980. She was the only child of Queen Wilhelmina and Prince Henry. She was married to German aristocrat Prince Bernhard of Lippe-Biesterfeld, with whom she had four children: Princess Beatrix (born 1938), Princess Irene (born 1939), Princess Margriet (born 1943), and Princess Christina (born 1947). During the Second World War she lived in exile with her children in Ottawa, Canada. She became Queen of the Netherlands with her mother's abdication in 1948 and was succeeded by Queen Beatrix after her own abdication in 1980. During her reign both Indonesia (Dutch East Indies) (proclaimed in 1945, recognized in 1949) and Suriname in 1975 became independent from the Netherlands. Her birthday was celebrated annually as Koninginnedag (Queen's Day) until the accession of her grandson King Willem-Alexander to the throne, when it was replaced with Koningsdag (King's Day). Upon her death at the age of 94, she was the longest-lived former ruling monarch in the world. She is commemorated in space, in the name of the asteroid 816 Juliana.
From the mid-1990s, Juliana's health declined and she also suffered the progressive onset of dementia. Juliana did not appear in public after this time. At the order of the Royal Family's doctors, Juliana was placed under 24-hour care. Prince Bernhard said in a television interview in 2001 that the former Queen was no longer able to recognise her family and that she had been suffering from Alzheimer's disease for several years.
Juliana died in her sleep on 20 March 2004, several weeks before her 95th birthday, at Soestdijk Palace in Baarn from complications of pneumonia, seventy years to the day after her grandmother, Queen Emma. She was embalmed, unlike her mother Wilhelmina, who chose not to be, and on 30 March 2004 interred beside her mother in the royal vaults under the Nieuwe Kerk in Delft. The memorial service made her ecumenical and often highly personal views on matters of religion public. The late Princess, a vicar said in her sermon, was interested in all religions and in reincarnation. Juliana's husband Prince Bernhard died eight months later aged 93, on 1 December 2004; his remains were placed next to hers. In 2009 an exhibition of portraits of Juliana, and objects from her life, was held at the Het Loo Palace to mark the centenary of her birth.
