In the contribution were shown threads devoted to Lithuania and Lithuanians, based on the data from the Silesian chronicles and annals that were written in Silesia in the Middle Ages. Considerable geographic distance and almost any direct contact caused relatively little interest in the presenting this subject by the Silesian chroniclers. A little more attention was paid in the connection with the baptism of the grand duke of Lithuania Jogaila, his accession to the Polish throne, and the Christianisation of Lithuanians. The victory of the Polish-Lithuanian troops over the Teutonic Knights in the battle of Grunwald in 1410 was also of interest of the historiographers.
