Grand duke of Lithuania from about 1316 to 1341 and founder of the Gediminid dynasty, who wrote to the pope and the Hanse inviting Europe into a pagan state, named Vilnius as his capital, and married his children into half the courts of eastern Europe.
Gediminas ruled Lithuania for about twenty-five years and turned a defensive pagan duchy into the largest state in eastern Europe. He did it with two instruments used at once: constant war against the Teutonic Order on the western frontier, and an open, sophisticated diplomacy that reached the pope at Avignon, the Hanseatic towns of the Baltic, and the Dominican and Franciscan orders.
His letters of 1322 to 1324 invited merchants, craftsmen and friars into Lithuania with land, freedom of worship and exemption from tolls, and they contain the first surviving mention of Vilnius as his royal city. He dangled his own baptism before Rome and then withdrew it. His children married into Poland, Moscow, Tver, Mazovia and Galicia, and the dynasty he founded ruled Lithuania and eventually Poland, Bohemia and Hungary.
His origins are obscure enough that even his relationship to the man he followed is argued over. He succeeded Vytenis around 1315 or 1316, and was probably his brother; the Teutonic chroniclers preferred a story in which the new grand duke had been his predecessor's stableman, which says more about what the Order wished to believe about Lithuanian rulers than about the family.
He was born about 1275, on a modern estimate rather than a recorded date, and came to power already middle-aged, in a state that had spent two generations absorbing annual raids from Prussia and Livonia. What he inherited was a war. What he added was everything else.
Gediminas is unusual among pagan Lithuanian rulers in that some of his own words survive. Six letters dictated in his chancery between 1322 and 1324 are preserved in copies, and they show a ruler who could speak Latin Christendom's language fluently and use it for his own ends: courteous to the pope, blunt about the Order's hypocrisy, precise about the commercial terms he was offering. Whoever drafted them — Franciscan or Dominican scribes at his court, most likely — the strategy in them is his.
The Teutonic chroniclers who supply most of the rest, Peter of Dusburg and later Wigand of Marburg, wrote as his enemies and saw a treacherous pagan whose promises of baptism were bad faith. The judgement is self-serving, since the Order's existence depended on there being unconvertible pagans next door. But the episode they point at is real: in 1324 papal legates arrived to find Gediminas declining to be baptised and blaming his own scribes for having written more than he meant.
The Rus' and Polish material gives a third angle again, and it is the one that shows the method. In his charters to the Orthodox principalities he confirmed existing law and existing princes; at Vilnius he let Franciscans keep a church while the sacred fires burned; his daughters were baptised as required by the courts they married into. The consistent thing about him is not conviction but an unusual tolerance of other people's, used as an instrument of rule over a realm where most subjects were neither pagan nor Lithuanian.
At the end of 1322 Gediminas wrote to Pope John XXII, complaining that the Teutonic Order had come to the Baltic to conquer rather than to convert, and indicating that he was willing to accept baptism if the aggression stopped. On 25 January 1323 and again on 26 May he sent circular letters to Lübeck, Bremen, Rostock, Stralsund, Greifswald, Szczecin and Gotland, and to the Dominican and Franciscan provinces, addressed to "all merchants, craftsmen and farmers" of the Latin world.
The terms were specific and commercially serious. Incomers could enter and leave freely and were exempt from tolls; knights received estates, merchants the right to trade, craftsmen land and tools; farmers were offered years free of tribute. Churches were already standing at Vilnius and Naugardukas and priests were welcome. The Riga notary who copied the May letter on 18 July 1323 recorded that it was read aloud in the town, which is how the texts survived at all.
The diplomacy peaked in October 1323 with an assembly at Vilnius, where envoys of Riga, Dorpat, Denmark, the Franciscans, the Dominicans and the Teutonic Order itself agreed a general peace, confirmed on 2 October. Then it stalled: when papal legates reached Riga in 1324 and sent representatives on to Vilnius, Gediminas refused baptism outright, and the Order returned to war. His Samogitian subjects and his Orthodox ones both had reason to resist a Catholic conversion, and he had discovered the limits of what he could sell at home.
Vilnius enters written history in the letter of 25 January 1323, where Gediminas dates the document from his royal city — the first surviving mention of the place by name. He was not founding a settlement on empty ground; there was a castle on the hill at the junction of the Neris and the Vilnia, and Kernavė and Trakai had served as earlier seats. What he did was make it the permanent centre of a state that now needed a capital foreign merchants could find.
The story everyone knows is later. In it Gediminas hunts near the rivers, sleeps at the site, and dreams of an iron wolf on a hilltop howling with the voice of a hundred wolves; his pagan priest Lizdeika reads the dream as a command to build a city whose fame will carry as far as the howling. It is a good story and it is not evidence: it first appears in the Lithuanian Chronicles of the sixteenth century, roughly two hundred years after the event it describes, in a compilation written to give the dynasty a suitably grand origin.
What the documents show instead is deliberate urban policy — a walled castle complex on the hill and in the valley, a merchant community, Franciscan and Dominican houses, the terms of the 1323 letters designed to populate it. The city grew because it was advertised across the Baltic, which is a stranger and more interesting founding than the wolf.
War with the Teutonic Order was annual and never decisive in his lifetime. Gediminas beat off major attacks in 1317, 1320, 1322 and 1329, won an engagement at Medininkai in 1320, and sent his own raids into Prussia, Livonia and Brandenburg; the Order took castles on the Nemunas and lost them again. The frontier in 1341 was roughly where he had found it, which in the circumstances counted as success.
The gains were made in the other direction. Polotsk, Vitebsk, Minsk and the Pinsk lands came under Gediminid rule by conquest, inheritance and marriage, Kiev fell into his sphere after a victory on the Irpin river, and Volhynia came through his son Liubartas. He styled himself "king of the Lithuanians and many Ruthenians", and where he took Orthodox lands he confirmed their princes, their law and their church.
The marriages were the most durable weapon. His daughter Aldona married Casimir, heir to Poland, in 1325, converting a hostile frontier into an alliance against the Order; Anastasia married Simeon, grand prince of Moscow; Maria married Dmitry of Tver; Elžbieta married Wacław of Płock; Eufemija married Bolesław-Jerzy II of Galicia. His sons took the duchies that made up the state — Algirdas at Vitebsk, Kęstutis at Trakai, Liubartas in Volhynia, Narimantas at Polotsk — an arrangement that gave the next generation both a working federation and a supply of rival claims.
