In 1386, Grand Duke [[Władysław II Jagiełło|Jogaila]] of [[Grand Duchy of Lithuania|Lithuania]] converted to [[Catholic Church|Catholicism]] and married Queen Jadwiga of Poland. This act enabled him to become a king of Poland himself,<ref name="playground I xxviii-xxix">{{Harvnb|Davies|2005a|pp=xxviii–xxix}}</ref> and he ruled as [[Władysław II Jagiełło]] until his death in 1434. The marriage established a [[personal union|personal]] [[Polish–Lithuanian union]] ruled by the [[Jagiellonian dynasty]]. The first in a series of formal "unions" was the [[Union of Krewo]] of 1385, whereby arrangements were made for the marriage of Jogaila and Jadwiga.<ref name="playground I xxviii-xxix"/> The Polish–Lithuanian partnership brought vast areas of [[Ruthenia]] controlled by the [[Grand Duchy of Lithuania]] into Poland's sphere of influence and proved beneficial for the nationals of both countries, who coexisted and cooperated in one of the largest political entities in Europe for the next four centuries. When Queen Jadwiga died in 1399, the Kingdom of Poland fell to her husband's sole possession.<ref name="playground I xxviii-xxix"/><ref>{{Harvnb|Wyrozumski|1986|pp=178–195}}.</ref>

In the [[Baltic Sea]] region, Poland's struggle with the Teutonic Knights continued and culminated in the [[Battle of Grunwald]] (1410),<ref name="playground I xxviii-xxix"/> a great victory that the Poles and Lithuanians were unable to follow up with a decisive strike against the main seat of the [[State of the Teutonic Order|Teutonic Order]] at [[Malbork Castle]]. The [[Union of Horodło]] of 1413 further defined the evolving relationship between the Kingdom of Poland and the Grand Duchy of Lithuania.<ref name="playground I xxviii-xxix"/><ref>{{Harvnb|Wyrozumski|1986|pp=195–201}}.</ref>

The privileges of the ''[[szlachta]]'' (nobility) kept expanding and in 1425 the rule of ''[[Neminem captivabimus]]'', which protected the noblemen from arbitrary royal arrests, was formulated.<ref name="playground I xxviii-xxix"/>
