In the 10th century, the area became part of the emerging Polish state under its first historic ruler Mieszko I.
In 1242, Duke Casimir I of Kuyavia from the Piast dynasty stayed in Sompolno, and issued a privilege for the Sulejów Abbey there.
A route connecting Warsaw with Poznań and Dresden ran through the town in the 18th century and King Augustus III of Poland often traveled that route.
[3] During the German occupation of Poland (World War II), Sompolno was renamed to Deutscheck between 1939 and 1943 and then later to Deutscheneck between 1943 and 1945[4] in an attempt to erase traces of Polish origin.
