Selma Ottilia Lovisa Lagerlöf (] ; 20 November 1858 – 16 March 1940) was a Swedish author and teacher.
 She was the first female writer to win the Nobel Prize in Literature.
Wang Bao () (c. 84c.
 53 BCE), courtesy name Ziyuan (子淵), was a lyricist, writer, and a poet of the Classical Chinese poetry tradition, who was involved in the "Chu Ci" poetry revival which took place in the second part of Emperor Xuan's reign, and which led to development of parts of what would eventually be the final form of the early poetry anthology by the same name, compiled by Wang Yi: "Chu Ci" means "literature of Chu", Chu being the area of a former independent kingdom, located in what was from the viewpoint of the Han Dynasty the south of China.
 Wang Bao is particularly known today as the author of the "Chu Ci" section "Nine Regrets".
 Although not as famous as ""Li Sao"" or "Heavenly Questions", and despite (as have all the "Chu Ci" contents) having sometimes having had Qu Yuan credited as author, having his works included in one of the two major early anthologies of Chinese poetry helped to secure Wang Bao's legacy as poet and author.
 Wang Bao became famous during the reign of Han Dynasty emperor Emperor Xuan (r. 74 BCE – 49 BCE), and he attended the emperor and the prince, his presumptive heir.

The Brazilian monarchy came to an end on November 15, 1889, following a military coup which overthrew Emperor "Dom" Pedro II and established a republic.
 According to the Imperial Constitution (1824), the Brazilian monarchy was hereditary according to male-preference primogeniture among the dynastic descendants of Emperor Pedro I of Brazil, and the crown could only be inherited by one who held Brazilian nationality.
 The Imperial constitution also states that the Emperor and his heir presumptive should be Catholic, and the marriage of the princess heir presumptive required consent of the Emperor or the Assembly.
Orthodoxy, Autocracy, and Nationality (Russian: Правосла́вие, самодержа́вие, наро́дность, "Pravoslaviye, Samoderzhaviye, Narodnost′" ), also known as Official Nationality, was the dominant ideological doctrine of Russian emperor Nicholas I.
 It was "the Russian version of a general European ideology of restoration and reaction" that followed the Napoleonic Wars.
The Emperor of Portugallia (Swedish: Kejsarn av Portugallien) is a novel by Nobel-laureate Selma Lagerlöf, published in 1914 with drawings by Albert Engström.
 Lagerlöf called it a "Swedish King Lear".
 The novel was a success with critics and readers, newspaper reviewers said the novel was at the same level as Lagerlöf's earlier novels "Gösta Berling's Saga" and the first part of "Jerusalem".
 It has been filmed three times: 1925, 1944 and 1992.
 An English translation by Velma Swanston Howard was published in 1916.

Nicholas I (Russian: Николай I Павлович , "Nikolay I Pavlovich" ; 6 July [O.S. 25 June] 1796 – 2 March [O.S. 18 February] 1855 ) was the Emperor of Russia from 1825 until 1855.
 He was also the King of Poland and Grand Duke of Finland.
 He is best known as a political conservative whose reign was marked by geographical expansion, repression of dissent, economic stagnation, poor administrative policies, a corrupt bureaucracy, and frequent wars that culminated in Russia's defeat in the Crimean War of 1853–56.
 His biographer Nicholas V. Riasanovsky says that Nicholas displayed determination, singleness of purpose, and an iron will, along with a powerful sense of duty and a dedication to very hard work.
 He saw himself as a soldier—a junior officer totally consumed by spit and polish.
 A handsome man, he was highly nervous and aggressive.
 Trained as an engineer, he was a stickler for minute detail.
 In his public persona, says Riasanovsky, "Nicholas I came to represent autocracy personified: infinitely majestic, determined and powerful, hard as stone, and relentless as fate."
 His reign had an ideology called "Official Nationality" that was proclaimed officially in 1833.
 It was a reactionary policy based on orthodoxy in religion, autocracy in government, and Russian nationalism.
 He was the younger brother of his predecessor, Alexander I.
 Nicholas inherited his brother's throne despite the failed Decembrist revolt against him and went on to become the most reactionary of all Russian leaders.
 His aggressive foreign policy involved many expensive wars, having a disastrous effect on the empire's finances.
