The Kolašin Affair (Serbian: Колашинска афера ) was a rebellion in the Montenegrin military against the dictatorship of the Prince of Montenegro, Nikola I Petrović-Njegoš, that broke out in 1909.
 It followed the failed Bombaš Affair (Бомбашка афера), a conspiracy organized in 1907 by a group of Montenegrin students connected to the Black Hand to break the Montenegrin government through terrorist attacks (with bombs, hence "Bombaši"), and ultimately unite Montenegro with Serbia, that was detected and led to numerous arrests in 1908.
 In the same year, a secret organization of Montenegrin politicians and political emigrees in Belgrade in opposition to Nikola I was formed.
 The organization's statute said that Nikola I was to be killed.
 The organization planned to free the "Bombaši" and change Tomanović's reactionary regime.
 The organization had important subsidiaries in Vasojevići, Kuči and Bratonožići, and allegedly had 1,000 members.
 It was detected by the Montenegrin police and led to the imprisonment and death sentences of the conspirators.
 The two affairs led to deteriorating bilateral relations between Montenegro and Serbia.

 An exceptionally skilful wizard, his coldly sarcastic and controlled exterior conceals deep emotions and anguish.
 A Professor at Hogwarts School of Witchcraft and Wizardry, Snape is hostile to the series' protagonist, Harry, the moment he sets foot in Snape's classroom; this hostility is rooted in Harry's resemblance to Harry's father James, who bullied and harassed Snape during their time at Hogwarts.
 Though philosophically attracted to the Dark Arts and Lord Voldemort's ideology of wizard supremacy, Snape's love for Muggle-born Lily Evans, Harry's mother, eventually compels him to defect from the Death Eaters.
 Snape becomes a double-agent on behalf of Albus Dumbledore and the Order of the Phoenix, and protects Harry throughout the series.

The Street is a novel published in 1946 by African-American writer Ann Petry.
 Set in World War II era Harlem, it centers on the life of Lutie Johnson.
 Petry's novel is a commentary on the social injustices that confronted her character, Lutie Johnson, as a single black mother in this time period.
 Lutie is confronted by racism, sexism, and classism on a daily basis in her pursuit of the American dream for herself and her son, Bub.
 Lutie fully subscribes to the belief that if she follows the adages of Benjamin Franklin by working hard and saving wisely, she will be able to achieve the dream of being financially independent and move from the tenement in which she lives on 116th Street.
 Franklin is embodied in the text through the character Junto, named after Franklin's secret organization of the same name.
 It is Junto, through his secret manipulations to possess Lutie sexually, who ultimately leads Lutie to murder Junto's henchman, Boots.
 Junto represents Petry's deep disillusionment with the cultural myth of the American dream.
