The Last King of Scotland is a 2006 historical drama film based on Giles Foden's novel "The Last King of Scotland" (1998), adapted by screenwriters Peter Morgan and Jeremy Brock, and directed by Kevin Macdonald.
 The film was a co-production between companies from the United Kingdom and Germany.
Don Carlos, Prince of Bourbon-Two Sicilies, Infante of Spain (Full Italian name: "Carlo Maria Francesco d'Assisi Pasquale Ferdinando Antonio di Padova Francesco de Paola Alfonso Andrea Avelino Tancredi, Principe di Borbone delle Due Sicilie, Infante di Spagna"; 10 November 1870, , Bolzano, Italy – 11 November 1949, Seville, Spain) was the son of Prince Alfonso of the Two Sicilies, Count of Caserta and his wife Princess Maria Antonietta of Bourbon-Two Sicilies, and nephew of the last King of the Two Sicilies, Francis II.
Umberto II (Italian: "Umberto Nicola Tommaso Giovanni Maria di Savoia" ; 15 September 190418 March 1983), was the last King of Italy.
 He reigned for 34 days, from 9 May 1946 to 12 June 1946, although he had been "de facto" head of state since 1944, and was nicknamed the May King (Italian: Re di Maggio ).
Italy, as a single nation state, began only in 1861, after the Piedmont-based Kingdom of Sardinia conquered most of present-day Italy.
 At that point, titles were recognized to all who held them according to the law of so-called "pre-unitarian" States.
 Consequently, the Kingdom of Italy had several different nobility traditions, one for each pre-unitarian State and one for the unified state (that was actually the Piedmontese-Savoyard one).
 That is why the Italian College of Arms, called "Consulta araldica" (heraldic council), was organized in 14 "regional" commissions.
 Common rules concerning all titles were established only in 1926.
 That is why a list of Italian marquisates has to be divided into different pre-unitarian lists, plus a unified list for titles granted after 1861.
 The latter should be completed with titles granted by the last King of Italy, Humbert II, during his exile and after the proclamation of the republic (1946), until his death in 1983: these concessions base upon the fact that he was not defeated in war and thus remained a king, that is a "fons honorum", but this issue is controversial, titles granted by a non-reigning king not being recognized by most noble and royal families in Europe.
 Only the Sovereign Military Order of Malta and the Corpo della Nobiltà Italiana recognize these titles, while the CILANE treats them as mere titles of courtesy.
Meresankh I ("She loves life") was Ancient Egyptian kingʻs wife and the mother of King Sneferu.
 She may have been a wife of King Huni, the last king of the 3rd dynasty.
Stanisław II Augustus (also Stanisław August Poniatowski; born Stanisław Antoni Poniatowski; 17 January 1732 – 12 February 1798) was the last King of Poland, Grand Duke of Lithuania and the last monarch of the united Polish–Lithuanian Commonwealth (1764–95).
 He remains a controversial figure in Polish history.
 Recognized as a great patron of the arts and sciences and an initiator and firm supporter of progressive reforms, he is also remembered as the last king of the Commonwealth whose election was marred by Russian involvement.
 He is criticized primarily for his failure to stand against the partitions, and thus to prevent the destruction of Poland.
Netjerkare Siptah (also Neitiqerty Siptah and likely the same person as Nitocris) was an Ancient Egyptian pharaoh, the seventh and last ruler of the 6th Dynasty.
 Alternatively some scholars classify him as the first king of the combined 7th and 8th Dynasties.
 As the last king of the 6th Dynasty, Netjerkare Siptah is considered by some Egyptologists to be the last king of the Old Kingdom period.
Princess Maria Beatrice of Savoy (born 2 February 1944) is the youngest daughter of Italy's last King, Umberto II, and his wife, Queen Marie José.
Jian, King of Qi (; reigned 264–221 BC) was the last king of Qi, one of the seven major states of the Warring States period of ancient China.
 His personal name was Tian Jian (田建), ancestral name Gui, and he did not have a posthumous title because he was the last king of Qi.
Princess Yolanda of Savoy (1 June 1901 – 16 October 1986) was the eldest daughter of King Victor Emmanuel III of Italy and his wife Queen Elena of Montenegro, and the sister of Umberto II, the last king of Italy.
