Question: Butautas attempted to depose the uncle who ruled the Lithuanians during what period?

full_context: Document 1: Michael Žygimantaitis: Michael Žygimantaitis (Lithuanian: "Mykolas Žygimantaitis" , Polish: "Michał Bolesław Zygmuntowicz" ; before 1406 – shortly before February 10, 1452 in Moscow) was the last male descendant of Kęstutis, Grand Duke of Lithuania. He supported his father Sigismund Kęstutaitis in power struggles with Švitrigaila. In 1435 he led his father's army to victory in the Battle of Pabaiskas. After his father's assassination in 1440, Michael unsuccessfully fought against Casimir IV Jagiellon for the title of the Grand Duke of Lithuania. At first Michael was supported by Samogitia, but in 1441 Casimir issued a privilege confirming Samogitia's semi-autonomous status and thus avoiding a civil war. Until 1447 he was supported by Dukes of Masovia. In 1448 Michael asked help from the Crimean Khanate. With their help he attacked and shortly took control of Kiev, Starodub, Novhorod-Siversky. Soon he was captured and transported to the Grand Duchy of Moscow where he died under unclear circumstances (possibly poisoned). He was buried in Vilnius Cathedral.
Document 2: Daujotas: Daujotas was one of the 5 elder Lithuanian dukes mentioned in the peace treaty with Halych-Volhynia in 1219. In the same document Vilikaila is mentioned as brother of Daujotas which suggests that Daujotas was the older or perhaps more influential brother. The brothers are not mentioned in any other sources. Tomas Baranauskas, a modern Lithuanian historian, believes that Vilikaila and Daujotas might be sons of Stekšys, a Lithuanian duke killed in 1214.
Document 3: Lithuanian Civil War (1389–92): The Lithuanian Civil War of 1389–92 was the second civil conflict between Jogaila, King of Poland and Grand Duke of Lithuania, and his cousin Vytautas. At issue was control of the Grand Duchy of Lithuania, then the largest state in Europe. Jogaila had been crowned King of Poland in 1386; he installed his brother Skirgaila as ruler of Lithuania. Skirgaila proved unpopular and Vytautas attempted to depose him. When his first attempt to take the capital city of Vilnius failed, Vytautas forged an alliance with the Teutonic Knights, their common enemy – just as both cousins had done during the Lithuanian Civil War between 1381 and 1384. Vytautas and the Knights unsuccessfully besieged Vilnius in 1390. Over the next two years it became clear that neither side could achieve a quick victory, and Jogaila proposed a compromise: Vytautas would become Grand Duke and Jogaila would remain Superior Duke. This proposal was formalized in the Ostrów Agreement of 1392, and Vytautas turned against the Knights. He went on to reign as Grand Duke of Lithuania for 38 years, and the cousins remained at peace.
Document 4: Dausprungas: Dausprungas (also "Dovsprunk" in Russian sources, died before 1238) was the older brother of Mindaugas, the first King of Lithuania. Dausprungas is mentioned in the peace treaty with Galicia–Volhynia in 1219 among the 21 early dukes of Lithuania as one of the five elder dukes, the other four being Živinbudas, Daujotas, Mindaugas and Viligaila (Daujotas' brother). Since Dausprungas is the only known brother of Mindaugas, Mindaugas' nephews Edivydas and Tautvilas are presumed to be his sons. If that is true, then Dausprungas is father-in-law of Daniel of Halych and he was also married to Vykintas' sister. Because it is known that Mindaugas used to kill his relatives to gain power and because Dausprungas is not mentioned in any other sources, some imply that he was killed by Mindaugas, but others rebut since his sons still ruled their lands in 1248.
Document 5: Vaidotas: Vaidotas or Wojdat (fl. 1362) was a son of Kęstutis, Grand Duke of Lithuania. In reliable historical sources he is mentioned only twice: as defender of Kaunas Castle in 1362 and as ruler of Navahrudak. Due to very limited information, his life is subject to wide-ranging theories by historians.
Document 6: Andrei of Polotsk: Andrei of Polotsk (Belarusian: Андрэй Альгердавіч , Lithuanian: "Andrius Algirdaitis" Polish: "Andrzej Olgierdowic" , ca. 1325 – 12 August 1399, in the Battle of the Vorskla River) was the eldest son of Algirdas, Grand Duke of Lithuania, and his first wife Maria of Vitebsk. He was Duke of Pskov (through his deputy Yuri, 1342–1348) and Polotsk (1342–1387). As the eldest son of the Grand Duke, Andrei claimed his right to the throne after his father's death in 1377. Algirdas left Jogaila, his eldest son with his second wife Uliana of Tver, as the rightful heir. Andrei's rivalry with Jogaila, Grand Duke of Lithuania and later King of Poland, eventually led to his demise.
Document 7: Butautas: Butautas (baptized "Henryk"; died on May 7, 1380 in Prague) was a son of Kęstutis, Grand Duke of Lithuania. He attempted to depose his uncle Algirdas and usurp power in Lithuania, but failed and was forced into exile. He joined the court of the Holy Roman Emperor and even inspired a poem about conversion to Christianity. Butautas is sometimes confused with his brother Vaidotas.
Document 8: Algirdas: Algirdas (Belarusian: Альгерд , Russian: Ольгерд , Polish: "Olgierd" ;  1296  – May 1377) was a ruler of medieval Lithuania. He ruled the Lithuanians and Ruthenians from 1345 to 1377. With the help of his brother Kęstutis (who defended the western border of the Duchy) he created an empire stretching from the present Baltic states to the Black Sea and to within fifty miles of Moscow.
Document 9: Mikhailo Olelkovich: Mikhailo Aleksandrovich Olelkovich (executed on August 30, 1481 in Vilnius) was a noble from the Olelkovich family of the Grand Duchy of Lithuania. He was the brother of Prince Simeon Olelkovich of Kiev and cousin of Grand Prince Ivan III of Moscow. Mikhailo was allegedly involved both in bringing the Judaizer Heresy to Novgorod and the failed defection of the city to the Grand Duchy of Lithuania in 1471. He also organized a coup against Casimir IV Jagiellon, King of Poland and Grand Duke of Lithuania, but was discovered and executed in 1481. Mikhailo's son Semen continued the family line.
Document 10: Lithuanian Civil War (1381–84): The Lithuanian Civil War of 1381–1384 was the first struggle for power between the cousins Jogaila, Grand Duke of Lithuania and later King of Poland, and Vytautas the Great. It began after Jogaila signed the Treaty of Dovydiškės with the Teutonic Knights which was aimed against his uncle Kęstutis, father of Vytautas. Kęstutis briefly seized power in the Grand Duchy, but was betrayed by adherents of Jogaila primarily from Vilnius. During negotiations for a truce Kęstutis and Vytautas were arrested and transported to the Kreva Castle. Kęstutis died there a week later but Vytautas managed to escape and then sought an alliance with the Teutonic Knights. Subsequently their joint forces raided Lithuanian lands. Eventually the cousins were reconciled as Jogaila needed internal stability in anticipation of negotiations with the Grand Duchy of Moscow and the Kingdom of Poland regarding the possible Christianization of Lithuania. The war did not settle the power struggle; it continued during the next Lithuanian Civil War (1389–1392) which was resolved by the signing of the Ostrów Agreement. After more than ten years of struggle, Vytautas finally became the Grand Duke of Lithuania and ruled the country for thirty-eight years.
Document 11: Vytautas: Vytautas (c. 1350 – October 27, 1430), also known as Vytautas the Great (Lithuanian: "   ", Belarusian: "Вітаўт Кейстутавіч (Vitaŭt Kiejstutavič)" , Polish: "Witold Kiejstutowicz" , Rusyn: "Vitovt", Latin: "Alexander Vitoldus") from the 15th century onwards, was a ruler of the Grand Duchy of Lithuania, which chiefly encompassed the Lithuanians and Ruthenians. He was also the Prince of Hrodna (1370–1382), Prince of Lutsk (1387~1389), and the postulated king of the Hussites.
Document 12: Kęstutis: Kęstutis (] ; born ca. 1297, died on 3 August or 15 August 1382 in Kreva) was a ruler of medieval Lithuania. He was the Duke of Trakai and governed the Grand Duchy of Lithuania, 1342–82, together with his brother Algirdas (until 1377), and with his nephew Jogaila (until 1381). He ruled over the Lithuanians and Ruthenians.
Document 13: Ruadhri of Bute: Ruadhri is an obscure 13th-century noble, who claimed the Isle of Bute through hereditary descent. Outlawed by King Alexander III of Scotland, because of attacks against Scottish lands, which he had undertaken as a result of him being denied his declared patrimony to the Isle of Bute through his hereditary right. When King Hakon IV of Norway began his 1263 expedition against Scotland, Ruadhri presented himself to Hakon and swore fealty to the King of Norway. He was allowed to participate in the attack on Bute, as part of the campaign, with Rothesay Castle surrendering. He took revenge on the garrison killing nine upon their retreat. He was granted the Isle of Bute by King Hakon, however he disappears from contemporary records shortly afterwards.
