Ruthenian language
Algirdas balanced himself between Moscow principality and Poland, spoke [[Lithuanian language|Lithuanian]] and [[Ruthenian language|Ruthenian]] (among other languages) and followed the majority of his [[paganism|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 [[Jagiellons|the dynasty]] which ruled Lithuania and Poland for nearly 200 years.
