# Algirdas

Algirdas (Belarusian: Альгерд, romanized: Alhierd; Ukrainian: Ольге́рд, О́льґерд, romanized: Olherd, Olgerd, Polish: Olgierd; c. 1296 – May 1377) was Grand Duke of Lithuania 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 80 kilometres (50 miles) of Moscow.

## Early life and rise to power

Algirdas was one of the seven sons of Grand Duke Gediminas. Before his death in 1341, Gediminas divided his domain, leaving his youngest son Jaunutis in possession of the capital, Vilnius. With the aid of his brother, Kęstutis, Algirdas drove out the incompetent Jaunutis and declared himself Grand Duke in 1345. He devoted the next thirty-two years to the development and expansion of the Grand Duchy of Lithuania.
After becoming the ruler of Lithuania, Algirdas was titled the King of Lithuania (Latin: rex Letwinorum) in the Livonian Chronicles instead of the terms knyaz (English: prince, duke) or velikiy knyaz (grand prince).
Two factors are thought to have contributed to this result: the political sagacity of Algirdas and the devotion of Kęstutis. The division of their dominions is illustrated by the fact that Algirdas appears almost exclusively in East Slavic sources, while Western chronicles primarily describe Kęstutis. Lithuania was surrounded by enemies. The Teutonic Order in the northwest and the Golden Horde in the southeast sought Lithuanian territory, while Poland to the west and the Moscow principality to the east were generally hostile competitors.

## Expansion of Lithuania

   "The entire Rus' should belong to the Grand Duchy of Lithuania"
Algirdas held his own, also acquiring influence and territory at the expense of the Moscow principality and the Golden Horde and extending the borders of the Grand Duchy of Lithuania to the Black Sea. His principal efforts were directed toward securing the Slavic lands which were part of the former Kievan Rus'. Although Algirdas engineered the election of his son Andrius as Prince of Pskov and a powerful minority of Novgorod Republic citizens supported him against the Moscow principality, his rule in both commercial centres was (at best) precarious.
Algirdas occupied the important principalities of Smolensk and Bryansk. Although his relationship with the grand dukes of Moscow principality was generally friendly (demonstrated by his marriages to two Orthodox Russian princesses), he besieged Moscow in 1368 and 1370 during the Lithuanian–Muscovite War (1368–1372). An important feat by Algirdas was his victory over the Tatars in the Battle of Blue Waters at the Southern Bug in 1362, which resulted in the breakup of the Kipchaks and compelled the khan to establish his headquarters in the Crimea.
In a 1371 letter to Philotheus Kokkinos, the Ecumenical Patriarch of Constantinople, Algirdas titled himself as a Lithuanian King, demanded a separate metropolitan bishop (from Moscow) for Kyiv, Smolensk, Tver, Little Russia, Novosil, and Nizhny Novgorod, and denied Muscovite complaints that he attacked Moscow without a reason.

## Religion and death

According to modern historians, "For Gediminas and Algirdas, retention of paganism provided a useful diplomatic tool and weapon ... that allowed them to use promises of conversion as a means of preserving their power and independence". Hermann von Wartberge and Jan Długosz described Algirdas as a pagan until his death in 1377. Contemporary Byzantine accounts support the Western sources; future Patriarch Nilus described Algirdas as a "fire-worshipping prince" and another patriarch, Philotheus, excommunicated all Ruthenian noblemen who helped the "impious" Algirdas. His pagan beliefs were also mentioned in 14th-century Byzantine historian Nicephorus Gregoras' accounts.
After his death, Algirdas was burned on a ceremonial pyre with 18 horses and many of his possessions in a forest near Maišiagala, probably in the Kukaveitis forest shrine located at 54°55′42″N 25°01′04″E﻿ / ﻿54.92833°N 25.01778°E﻿ / 54.92833; 25.01778. His alleged burial site has undergone archaeological research since 2009. Algirdas' descendants include the Trubetzkoy, Czartoryski and Sanguszko families.
Although Algirdas was said to have ordered the death of Anthony, John, and Eustathius of Vilnius, who were later glorified as martyrs of the Russian Orthodox Church, the 16th-century Bychowiec Chronicle and 17th-century Hustynska Chronicle maintain that he converted to Orthodox Christianity some time before his marriage to Maria of Vitebsk in 1318. Several Orthodox churches were built in Vilnius during his reign, but later assertions about his baptism are uncorroborated by contemporary sources. Despite contemporary accounts and modern studies, however, some Russian historians (such as Batiushikov) claim that Algirdas was an Orthodox ruler. The Kiev Monastery of the Caves' commemorative book, underwritten by Algirdas' descendants, recorded his baptismal name as Demetrius during the 1460s. Algirdas married Uliana of Tver by 1350.
Following Wojciech Wijuk Kojałowicz and Macarius I, Volodymyr Antonovych writes that Algirdas took monastic vows several days before his death and was interred at the Cathedral of the Theotokos in Vilnius under the monastic name Alexius.

## Assessment

Algirdas balanced himself between Moscow principality and Poland, spoke Lithuanian and Ruthenian (among other languages) and followed the majority of his pagan and Orthodox subjects rather than to alienate them by promoting Roman Catholicism. His son Jogaila ascended the Polish throne, converted to Roman Catholicism and founded the dynasty which ruled Lithuania and Poland for nearly 200 years.
Algirdas (Belarusian: Альгерд, Alhierd) is also widely honoured in Belarus as a unifier of all Belarusian lands within one state, a successful military commander and ruler of medieval Belarus. A monument to him has been erected in Vitsebsk in 2014, as part of the celebration of the city's 1040th anniversary. Algirdas was Duke of Vitebsk for over 20 years before becoming Grand Duke of Lithuania.
In December 2022, the National Bank of the Republic of Belarus issued a commemorative coin dedicated to the Battle of Blue Waters with a portrait of Algirdas.

## Popular culture

Algirdas features in the 2021 video game Age of Empires II: Definitive Edition in the Dawn of the Dukes campaign, detailing the exploits of himself and his brother Kęstutis.
