Grand Duke of Lithuania (1430–1432), the brother of Jogaila whose bid for an independent, Orthodox-backed Lithuania against Poland plunged the realm into civil war.
Švitrigaila was Grand Duke of Lithuania from 1430 to 1432, the restless and rebellious youngest brother of Jogaila. He succeeded the great Vytautas as ruler of Lithuania on his cousin's death, and at once pursued a policy that set Lithuania against Poland: he sought to make the grand duchy fully independent of the Polish crown and drew his support from the Orthodox Ruthenian nobility of the eastern lands.
His challenge to the Polish-Lithuanian union provoked a coup in 1432 by the pro-Polish party, who raised Sigismund Kęstutaitis in his place. The result was a bitter civil war that raged for years across Lithuania and Ruthenia, and though Švitrigaila fought on, he was ultimately defeated, ending his long life as merely a duke in Volhynia.
Švitrigaila was born about 1370, the youngest son of Grand Duke Algirdas and a brother of Jogaila. Ambitious and turbulent from his youth, he spent decades as a perennial malcontent within the Gediminid family, repeatedly intriguing and rebelling against his brother Jogaila and his cousin Vytautas, and at times allying with the Teutonic Knights and other enemies of the union.
When the long-dominant Vytautas died in 1430 without a son, the Lithuanian nobles, asserting their right to choose, elected Švitrigaila grand duke — to the alarm of the Poles.
Švitrigaila is remembered as a bold, energetic, and deeply unstable figure — a lifelong rebel whose driving passion was resistance to Polish domination of Lithuania, but whose impulsiveness and poor judgement repeatedly wrecked his own cause. Restless and quarrelsome, he made and broke alliances with reckless abandon and alienated even his natural supporters.
Yet his career gave voice to something real and lasting: the desire of many Lithuanians, and especially of the Orthodox Ruthenian nobility, for a Lithuania independent of Poland and respectful of their faith and rights. That he championed the Orthodox lords, previously excluded from the highest offices, made him a figure of genuine significance in the history of the grand duchy — even as his own volatility ensured that the cause he embodied went down to defeat.
As grand duke, Švitrigaila broke sharply with Poland. He refused to acknowledge Polish overlordship, courted the Emperor Sigismund and the Teutonic Order, and above all drew his strength from the Orthodox nobility of the vast Ruthenian lands, promising them a share in power. This threatened to pull Lithuania out of its union with Poland altogether.
In 1432 the pro-Polish party struck back in a coup that installed Sigismund Kęstutaitis as grand duke. Švitrigaila fled to the Ruthenian east, where his Orthodox supporters proclaimed him, and a long and destructive civil war followed. Defeated in a great battle at Wiłkomierz in 1435, his cause collapsed, though he lingered for years as a claimant before finally accepting a modest lordship in Volhynia.
Švitrigaila died at Lutsk on 10 February 1452, an old man of over eighty, holding only the duchy of Volhynia. He was the last of the sons of Algirdas.
Švitrigaila is remembered as the grand duke whose war for an independent Lithuania and for the rights of the Orthodox nobility failed, but whose challenge marked a decisive moment in the long struggle over the nature of the Polish-Lithuanian union. His defeat confirmed the union and the primacy of the Catholic nobility, yet the grievances he championed — Lithuanian autonomy and Orthodox rights — would echo through the later history of the grand duchy.
