. Algirdas, who was the Grand Duke, spent most of his time dealing with the eastern provinces of the Grand Duchy, inhabited by Ruthenians of Orthodox faith. Kęstutis in the name of Algirdas handled most of the affairs in the western part, including defense against the Teutonic Knights. Algirdas died in 1377 and left the throne to Jogaila, his eldest son from the second marriage with
Uliana of Tver Uliana Aleksandrovna ( – 17 March 1391) was a grand duchess of Lithuania as the second wife of Algirdas. She was the daughter of Alexander of Tver and Anastasia of Galicia, daughter of Yuri I of Galicia. Life After her father and eldes ...
. Kęstutis and Vytautas continued to collaborate with Jogaila even when his right of inheritance was challenged by Andrei of Polotsk, Algirdas' eldest son from his first marriage with Maria of Vitebsk. The Teutonic Knights continued their crusade against pagan Lithuania. A large campaign was organized in winter of 1378, during which the Teutons reached Brest and as far as the

. It was the last treaty that Kęstutis and Jogaila signed jointly. It was followed by a three-day secret negotiations between Jogaila and the Knights in Vilnius. However, the truce protected only the Christian lands in the south, while Kęstutis' pagan realms in northern and western Lithuania were still vulnerable to Teutonic attacks. In February 1380, Jogaila, without Kęstutis, made a five-month truce with the Livonian Order to protect his Lithuanian domains and cease Livonian support to Andrei of Polotsk. On May 31, 1380, Jogaila and Grand Master Winrich von Kniprode signed the secret Treaty of Dovydiškės. The clauses of the treaty were, overall, convoluted and not entirely clear. Based on the terms of the accord, Jogaila agreed not to intervene during attacks by the Teutonic Knights against Kęstutis or his children. However, if providing aid to Kęstutis were necessary to avoid any suspicions, it would not be a violation of the treaty. The treaty remains controversial as the motives behind it are not entirely clear. Some historians blame Uliana, mother of Jogaila, or his adviser Vaidila, others point out generational differences: Kęstutis was about 80 years old and determined not to accept Christianity, while Jogaila was about 30 and was looking for ways to convert and modernize the country. Still others have suggested that the treaty was primarily directed against Andrei and his allies – his brother Dmitry of Bryansk and Grand Duke of Moscow

recruited in Galicia–Volhynia. On August 3, 1382, the armies of Kęstutis and Jogaila met near Trakai for a decisive battle, but it never began. According to Teutonic sources, Kęstutis saw that Jogaila, aided by the Teutonic Knights, had superior forces when his Samogitian contingent was reluctant to fight. Both sides agreed to negotiate. Kęstutis and Vytautas arrived in Jogaila's camp, but were arrested and sent to a prison in the Kreva Castle. Their army was disbanded. On August 15, five days after imprisonment, Kęstutis was found dead by Skirgaila. Jogaila claimed that he had hanged himself, but rumors spread that he had been strangled. Jogaila organized a large pagan funeral to Kęstutis: his body was burned along with horses, weapons, and other treasures in Vilnius.


Vytautas' escape

Vytautas remained in prison until fall 1382. He managed to escape with help from his wife Anna, who received permission to visit her husband. According to different sources Vytautas exchanged clothes with either Anna or one of her female servants and sneaked out undetected. First he sought help from his sister

, then he turned to Siemowit IV, Duke of Masovia. Eventually he came to his enemies, the Teutonic Knights, asking for protection and military aid against Jogaila. According to Wigand of Marburg, Birutė, mother of Vytautas, was drowned in Brest, likely in response to his escape. Two of her relatives, Vidimantas and Butrimas, were also murdered. The Knights received Vytautas without enthusiasm. At the time Jogaila was negotiating with the Teutonic Order. On October 31, 1382, they formulated the Treaty of Dubysa in three separate acts. It was a reward for their help in defeating Andrei and Kęstutis. In it, Jogaila promised to accept Christianity within four years, become an ally of the Order, not to initiate a war without Order's approval, and cede Samogitia, which still supported Vytautas, up to the Dubysa River. However, ratification of the treaty was continuously put off. One of the reasons for the cooling relations was a war in

, that Jogaila had started without consulting the Knights. The Knights also attempted to play Vytautas and Jogaila off against each other. Other historians suggest that Jogaila was already thinking about an alliance with either Moscow or Poland. Eventually, in June 1383, a scheduled meeting between Jogaila and the Grand Master did not take place on a formal pretext and the alliance broke down. The Knights resumed their war with Lithuania.


Reconciliation

In early September, the Knights and Vytautas briefly took control of Trakai and unsuccessfully attacked Vilnius. On October 21, 1383, in Tapiau, in a small ceremony Vytautas was baptized in the Catholic rite, receiving the name of Wigand (Lithuanian: ''Vygandas'') after his godfather Wigand, komtur of Ragnit. Vytautas received New Marienburg, a castle on the

He then proceeded to burn two Teutonic castles on the

Aftermath

Vytautas returned to Lithuania without a clear written agreement with Jogaila. He received

, Vytautas was baptized in the Orthodox rite. Skirgaila continued to rule Trakai. Vytautas pledged loyalty to Jogaila and became one of the many regional dukes. Jogaila was considering different baptism proposals. He had already refused the Treaty of Dubysa with the Teutonic Knights. He negotiated with Moscow, but it was a dangerous ally and Orthodoxy would not save Lithuania from attacks by the Teutonic Knights. Furthermore, Muscovy lost some of its power and influence after the siege of Moscow in 1382 by the Mongols. A third option was presented by Poland: it was looking for a suitable groom for

between Lithuania and Poland. In 1386, he was baptized and crowned King. Skirgaila was left as his regent in Lithuania. Taking advantage of Jogaila's absence, Andrei of Polotsk renewed his bid for the throne of Lithuania. During this time Vytautas remained loyal and helped Jogaila and Skirgaila to defeat Andrei. On April 28, 1387, after Andrei's defeat, Skirgaila received Polotsk and Trakai – thus breaking the promise given to Vytautas that he would receive Trakai when Skirgaila received Polotsk. Trying to appease his cousin, Jogaila gave him Lutsk (but left a Pole in charge of Lubart's Castle) and

. This did not help and the relationship turned sour. At the same time dissatisfaction with Skirgaila's rule continued to grow among the Lithuanians, who resented growing Polish influence in the state. They wanted to maintain Lithuanian legal distinctiveness and reserve offices for the Lithuanians. The duped Teutonic Knights continued to demand Samogitia and continued to wage war. All these circumstances allowed Vytautas to renew his struggle for power. He escaped to the Teutonic Knights for the second time and waged another civil war. It ended with the

of 1392, wherein Vytautas acknowledged fealty to Jogaila and was granted extensive autonomy in Lithuania. Thus he became the Grand Duke of Lithuania and started his 38-year reign.
