Editing Yaroslav the Wise (section)

===Allies along the Baltic coast===
In his foreign policy, Yaroslav relied on a Scandinavian alliance and attempted to weaken the Byzantine influence on Kiev. According to ''Heimskringla'', Olaf the Swede made an alliance with Yaroslav, even though the alliance was not liked in Sweden, in order to declare war against [[Olaf II of Norway]]. This was sealed in 1019 when King Olof of Sweden married his daughter to Yaroslav instead of the Norwegian king. That led to protests in Sweden because the Swedes wanted to reestablish control over their lost eastern territories and bring in tribute from Kievan Rus', as his father [[Eric the Victorious]] had, but after years of war against Norway, Sweden no longer had the power to collect regular tributes from Kievan Rus', according to ''Heimskringla''. In 1022 Olaf was deposed and forced to give power to his son [[Anund Jakob]].<ref name="Snorre Sturluson 1992, pp. 89-95">Snorre Sturluson, Nordiska kungasagor. Vol. II.

In a successful military raid in 1030, he captured [[Tartu]], [[Estonia]] and renamed it Yuryev<ref>{{cite book|last1=Tvauri|first1=Andres|title=The Migration Period, Pre-Viking Age, and Viking Age in Estonia|date=2012|pages=33, 59, 60|url=https://www.etis.ee/Portal/Publications/Display/b80b6f11-43ed-4b8c-b616-48ac53b70ec5?language=ENG|access-date=27 December 2016}}</ref> (named after Yury, Yaroslav's [[patron saint]]) and forced the surrounding [[Ugandi County]] to pay annual tribute.

In 1031, he conquered [[Cherven cities]] from the Poles followed by the construction of [[Sutiejsk]] to guard the newly acquired lands. In c.1034 Yaroslav concluded an alliance with [[Kings of Poland|Polish King]] [[Casimir I the Restorer]], sealed by the latter's marriage to Yaroslav's sister, Maria.

Yaroslav's eldest son, [[Vladimir of Novgorod|Vladimir]], ruled in Novgorod from 1034 and supervised relations in the north.<ref name="martin"/>

Later in Yaroslav's reign, around c.1035, [[Ingvar the Far-Travelled]], [[Anund Jakob]]'s jarl, sent Swedish soldiers into Kievan Rus due to Olof's son wanting to assist his father's ally Yaroslav in his wars against the Pechenegs and Byzantines. Later, in c.1041 Anund Jakob tried to reestablish [[Sweden|Swedish]] control over the Eastern trade routes and reopen them.<ref>{{Cite web|url=http://viking-nevo.narod.ru/eng/expeditions/2004-vittfarne.html|title=Vittfarne expedition - Viking-Nevo}}</ref> The Georgian annals report 1000 men coming into [[Georgia (country)|Georgia]] but the original force was likely much larger, around 3,000 men.<ref>{{Cite web|url=https://www.georgianjournal.ge/discover-georgia/29710-vikings-in-georgia.html|title = Vikings… in Georgia?}}</ref>

Ingvar's fate is unknown, but he was likely captured in battle during the Byzantine campaigns or killed, supposedly in 1041. Only one ship returned to Sweden, according to the legend.<ref>{{Cite web|url=https://www.snerpa.is/net/forn/yngvar.htm|title = Yngvars saga víðförla}}</ref>
