Shvarn was married to the sister of Lithuania duke Voyshelk (son of Mindaugas: 1236-1263) and Voyshelk had a suport from him. In the beginning Voyshelk and Shvarn ruled together in Lithuania, while Shvarn possesed the Black Rus' lands. When Lithuanian lands were finally "safe", Voyshelk passed them on to Shvarn and went to a monastery himself. For this "kindness" duke Leo killed Voyshelk in a Volhynian monastery (in Volodymyr). Shvran did not rule long in Lithuania and after he died Traidenis became a great duke of Lithuania. The followong relations of Volhynian dukes with Lithuania were peaceful, beacuse Tatar-Mongol invasions into Lithuania (1275, 1277) organized by Leo of Galicia hindered this peace. Besides that Traidenis attempted to take a better control over the Black Rus' settling Prussians there (who were escaping from the advancement of German Crusaders). Duke of Volodymyr was against thsi but could not do anything. Clash between Volodymyr of Volhynia (son of Vasylko) with Sirputiy (the brother of Traidenis) resulted in taking of Turiysk by Volodymyr and they settled temporary peace with Traidenis.
The relations of Galician duke Leo with Lithuanian duke Traidenis first were quite friendly but then Traidenis took over Dorohychyn from Leo. Dorohychyn (now Drohiczyn in Poland) was a major trade center on the route from Lviv (Leopolis) to Torun and the Baltics. Peace was broken. Using his relatiosn with the Golden Horde, duke Leo sent messangers to Mengu-Timur, who sent him troops under the command of Yagurchyn (Yagurain) and khan ordered that all trans-Dnieper dukes (Roman, Oleh of Bryansk, Gleb of Smolensk, Pinsk and Turov dukes) and also Mstislav of Lutsk and Volodymyr of Volodymyr to go all with Leo. Leo took over control over Dorohoczyn and even occupied Novogorodok.

Relations of Leo of Galicia with khan Telebuga of Golden Horde and khan Nogay.
Galician Tatar relations were quite complicated. It is possible to think that Tatars-Mongols recognized Leo (Lev, son of Daniel of Halych) as a great ruler of Halych -Volhyn lands'. South esat Ukraine' suffered not only because it was under the rule of Golden Horde but it also experienced pressure from the horde of Nogay, who had created his center at the northern coast of the Black Sea. Nogay controlled a greater part of Ukrainian lowlands, including Galician lowlands (Ponyzzya).
After death of Mengu Timur (1280-1282), a double rule was established in Horde, which lasted until 1291. Khan Telebuga (the successor of Mengu-Timur) who took the Golden horde trone in 1287-1288, continued hostilies and fight against Nogay. It is possible to guess that presence of two centers of Tatar-Mongol rule caused two orientatiosn among local dukes. For example duke Leo maintained realatiosn with Nogay and with Mengu-Timur, while for duke of Vladimir, Mengu-Timur was once "great king" while Nogay was "cursed and unlawful".

After the next complaint (regarding Lithuania) arrived from Rus' kings not only to the Golden Horde but also to Nogay, he sent (around 1277) then his ambassodors "with letters" to Leo, Mstislav and Vladimir (such an order of listing dukes, was copied probably by Vladimir chronichle writer from khan's letter) saying "You always complain to me about Lithuania, thus I give you the army and a warlord Mamyshey with it, go with them!". Though, this raid was not successfull for Vladimir duke (Tatars fought separately around Novogorodok) and secondly duke Mstislav of Lutsk (in Volhynia) and George (or Yuri, son of Leo) together with Kholm (todays Chelm) warlord Tyuima fought at Gorodno (Hrodna) not with much luck.
We can see that Leo of Galicia was quite connected to Nogay, also from the next fact: After the death of duke Boleslaw (of Smaller Poland), duke Leo attempted to establish himself at Cracow throne or at least to occupy the town son the Vkrayina (= borderland, that is west of river Vepr / Wieprz) and in this attempt Leo asked for help from Nogay (and not from Golden Horde): Leo himself went to the "cursed and unlawful" Nogay to ask for help and khan Nogay gave him assistance and troops under the command of warlards Konchak (Konçak, probably from Cumans), Kuzey and Kubatan.
Also at this case, Khan Nogay ordered south eastern dukes to go on the raid on Cracow together with Leo. Leo was glad to advance with Tatars, while duke Mstislav (of Volhynia), duke Vladimir (of Vladimir) and his son Daniel (who died soon) went unwillingly being forced by Tatars. And during military actions, duke Vladimir delibirately stood "on the back". Since duke Leo did not succeed to take Cracow, Vladimir's chronichle-writer noted with gladness "that Galician duke returned home with great dishonour".
The growth of fight and tension between the Golden Horde khan Telebuga and Nogay, brought new troubles for Galicia and whole of south east Rus'. Sometimes, both khanes acted together, so it was during their raid on Hungary (1285). As a matter of rule, Galician and Rus' dukes were ordered to go on the raid together with them as well (Leo of Galicia and Mstislav of Volhynia departed themselves but duke Vladimir sent his army under the command of George (Yuri, son of Leo).

At this time, Polish duke Boleslaw invaded Galician lands (because of this duke Leo was freed from taking part in the raid after they entered Hungary). According to the Vladimir's chronchler, the raid of Tatar-Mongols on Hungary ended with no luck: khan Nogay turned going east to Brasov and khan Telebuga went "through the mountain". Nothing is said about Nogay further but it is said the second one got lost in the Carpathians and "left with shame".
The next raid of Tatars khans clearly showed disagreements and tensiosn between them. In 1286 khan Telebuga decided to oragnize the raid on Poland, and probably together with Nogay. For this purpose, khan Telebuga arrived with the armies to Nogay's headquarters but there was "a great disagreement between them" and in the end khan Telebuga moved against Poland himself. Telebuga gave order to be accompnied in the raid by all Galician- Volhynian and trans-Dnieper dukes. Thsi time, his way laid through Volhynia. At the river Horyn (Goryn), khan Telebuga was met with presents by duke Mstislav of Volhnynia. At Peremyl (now a small town on the south east of Volyn region in Western Ukraine) on the river Lypa Telebuga was greeted with presents by Vladimir (son of Vasylko) and at Buzhkovychi (today a village further east from Peremyl) khan was welcomed by Leo (son of Daniel) of Galicia.
Khan Telebuga left part of his troops in Volodymyr (then capital of Volhynian principality) and moved against Poland together with Rus' regiments. Note that Tatars-Mongols had plundered Volhynian land by that. Tatar-Rus' troops were advancing towards Cracow via Sandomyr (Sandomierz) and Zavykhost (Zawichost). But here was a surprise! Khan Telebuga learned "that Nogay went ahead of him to Cracow" and had to return back plundering Lviv lands on the way.
Khan Nogay had led his troops to Cracow also but by a different root - through western Galicia and Peremyshl (Przemysl). Because of this hatred between khans Telebuga and Nogay became even greater, being afraid of each other.
