Given the task definition and input, reply with output. In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: The term Belorussia (Russian: Белору́ссия, the latter part similar but spelled and stressed differently from Росси́я, Russia) first rose in the days of the Russian Empire, and the Russian Tsar was usually styled "the Tsar of All the Russias", as Russia or the Russian Empire was formed by three parts of Russia—the Great, Little, and White. This asserted that the territories are all Russian and all the peoples are also Russian; in the case of the Belarusians, they were variants of the Russian people.After the Bolshevik Revolution in 1917, the term "White Russia" caused some confusion, as it was also the name of the military force that opposed the red Bolsheviks. During the period of the Byelorussian SSR, the term Byelorussia was embraced as part of a national consciousness. In western Belarus under Polish control, Byelorussia became commonly used in the regions of Białystok and Grodno during the interwar period.The term Byelorussia (its names in other languages such as English being based on the Russian form) was only used officially until 1991, when the Supreme Soviet of the Byelorussian SSR decreed by law that the new independent republic should be called Republic of Belarus (Республика Беларусь spelled in Russian), and that its abridged form should be "Belarus". The law decreed that all the forms of the new term should be transliterated into other languages from their Belarusian language forms. The use of Byelorussian SSR and any abbreviations thereof were allowed from 1991 to 1993. Conservative forces in the newly independent Belarus did not support the name change and opposed its inclusion in the 1991 draft of the Constitution of Belarus.Accordingly, the name Byelorussia was replaced by Belarus in English. Likewise, the adjective Belorussian or Byelorussian was replaced by Belarusian in English. Belarusian is closer to the original Belarusian term of bielaruski. Belarusian intelligentsia in the Stalin era attempted to change the name from Byelorussia to a form of Krivia because of the supposed connection with Russia. Some nationalists object to the name for the same reason. Several local newspapers kept the old name of the country in Russian in their names, for example Komsomolskaya Pravda v Byelorussii, which is the localized publication of a popular Russian newspaper. Also, those who wish for Belarus to be reunited with Russia continue to use Belorussia. Officially, the full name of the country is "Republic of Belarus" (Рэспубліка Беларусь, Республика Беларусь, Respublika Belarus listen ).
What did Byelorussia become after 1991?
