Some context: Ivan IV Vasilyevich (Russian: Ivan Vasil'evich, tr. Ivan Vasilyevich; 25 August 1530 - 28 March [O.S. 18 March] 1584), commonly known as Ivan the Terrible or Ivan the Fearsome (Russian:  Ivan Groznyi  , Ivan Grozny; a better translation into modern English
Despite calamities triggered by the Great Fire of 1547, the early part of Ivan's reign was one of peaceful reforms and modernization. Ivan revised the law code, creating the Sudebnik of 1550, founded a standing army (the streltsy), established the Zemsky Sobor (the first Russian parliament of the feudal Estates type) and the council of the nobles (known as the Chosen Council), and confirmed the position of the Church with the Council of the Hundred Chapters (Stoglavy Synod), which unified the rituals and ecclesiastical regulations of the whole country. He introduced local self-government to rural regions, mainly in the northeast of Russia, populated by the state peasantry.  By Ivan's order in 1553 the Moscow Print Yard was established and the first printing press was introduced to Russia. Several religious books in Russian were printed during the 1550s and 1560s. The new technology provoked discontent among traditional scribes, leading to the Print Yard being burned in an arson attack. The first Russian printers, Ivan Fedorov and Pyotr Mstislavets, were forced to flee from Moscow to the Grand Duchy of Lithuania. Nevertheless, printing of books resumed from 1568 onwards, with Andronik Timofeevich Nevezha and his son Ivan now heading the Print Yard.  Ivan had St. Basil's Cathedral constructed in Moscow to commemorate the seizure of Kazan. There is a false legend that he was so impressed with the structure that he had the architect, Postnik Yakovlev, blinded so that he could never design anything as beautiful again. In reality, Postnik Yakovlev went on to design more churches for Ivan and the walls of the Kazan Kremlin in the early 1560s, as well as the chapel over St. Basil's grave that was added to St. Basil's Cathedral in 1588, several years after Ivan's death. Although more than one architect was associated with this name and constructions, it is believed that the principal architect is one and the same person.  Other events of this period include the introduction of the first laws restricting the mobility of the peasants, which would eventually lead to serfdom, instituted during the rule of future tsar Boris Godunov in 1597. (See also Serfdom in Russia.)

Some context: Osceola was named Billy Powell at birth in 1804 in the Creek village of Talisi. now known as Tallassee, Alabama, in current Elmore County. "The people in the town of Tallassee...were mixed-blood Native American/English/Irish/Scottish, and some were black. Billy was all of these."
Through the 1820s and the turn of the decade, American settlers kept up pressure on the US government to remove the Seminole from Florida to make way for their desired agricultural development. In 1832, a few Seminole chiefs signed the Treaty of Payne's Landing, by which they agreed to give up their Florida lands in exchange for lands west of the Mississippi River in Indian Territory. According to legend, Osceola stabbed the treaty with his knife, although there are no contemporary reports of this.  Five of the most important Seminole chiefs, including Micanopy of the Alachua Seminole, did not agree to removal. In retaliation, the US Indian agent, Wiley Thompson, declared that those chiefs were deposed from their positions. As US relations with the Seminole deteriorated, Thompson forbade the sale of guns and ammunition to them. Osceola, a young warrior rising to prominence, resented this ban. He felt it equated the Seminole with slaves, who were forbidden to carry arms.  Thompson considered Osceola to be a friend and gave him a rifle. Osceola had a habit of barging into Thompson's office and shouting complaints at him. On one occasion Osceola quarreled with Thompson who had the warrior locked up at Fort King for a two nights until he agreed to be more respectful. In order to secure his release, Osceola agreed to sign the Treaty of Payne's Landing and to bring his followers into the fort. After his humiliating imprisonment, Osceola secretly prepared vengeance against Thompson.  On December 28, 1835, Osceola, with the same rifle Thompson gave him, killed Wiley Thompson. Osceola and his followers shot six others outside Fort King, while another group of Seminole ambushed and killed a column of US Army, over 100 troops, marching from Fort Brooke to Fort King, in what Americans called the Dade Massacre. These nearly simultaneous attacks began the Second Seminole War.

Some context: The Romani (also spelled Romany , ), or Roma, are a traditionally itinerant ethnic group, living mostly in Europe and the Americas and originating from the northern Indian subcontinent, from the Rajasthan, Haryana, Punjab and Sindh regions of modern-day India and Pakistan. A DNA study conducted by Indian and Estonian research facilities shows that the Roma/Romani/Gypsy and Sinti people originate from the so-called "Untouchable" Dalit community from India. The Romani are widely known among English-speaking people by the exonym Gypsies (or Gipsies), which some people consider pejorative due to its connotations of illegality and irregularity. They are a dispersed people, but their most concentrated populations are located in Europe, especially Central, Eastern and Southern Europe (including Turkey, Spain and Southern France).
The English term Gypsy (or Gipsy) originates from the Middle English gypcian, short for Egipcien. The Spanish term Gitano and French Gitan have similar etymologies. They are ultimately derived from the Greek Aiguptioi (Aigyptioi), meaning Egyptian, via Latin. This designation owes its existence to the belief, common in the Middle Ages, that the Romani, or some related group (such as the Middle Eastern Dom people), were itinerant Egyptians. According to one narrative they were exiled from Egypt as punishment for allegedly harbouring the infant Jesus. As described in Victor Hugo's novel The Hunchback of Notre Dame, the medieval French referred to the Romanies as Egyptiens. The word Gypsy in English has become so pervasive that many Romani organizations use it in their own organizational names.  This exonym is sometimes written with capital letter, to show that it designates an ethnic group. However, the word is sometimes considered derogatory because of its negative and stereotypical associations. The Council of Europe consider that 'Gypsy' or equivalent terms, as well as administrative terms such as 'Gens du Voyage' (referring in fact to an ethnic group but not acknowledging ethnic identification) are not in line with European recommendations. In North America, the word Gypsy is most commonly used as a reference to Romani ethnicity, though lifestyle and fashion are at times also referenced by using this word.  Another common designation of the Romani people is Cingane (alt. Tsinganoi, Zigar, Zigeuner), which likely derives from Athinganoi, the name of a Christian sect with whom the Romani (or some related group) became associated in the Middle Ages.
