Nierodzim is a district (osiedle) of Ustroń, Silesian Voivodeship, Poland.

[2][3] Politically the village belonged then to the Duchy of Teschen, formed in 1290 in the process of feudal fragmentation of Poland and was ruled by a local branch of Piast dynasty.

After the 1540s Protestant Reformation prevailed in the Duchy of Teschen and later local Lutherans built a wooden church.

It was taken from them (as one from around fifty buildings) in the region by a special commission and given back to the Roman Catholic Church on 16 April 1654.

According to the censuses conducted in 1880, 1890, 1900 and 1910 the population of the municipality (together with the cadastral community of Bładnice Górne) grew from 578 in 1880 to 626 in 1910 with a majority being native Polish-speakers (98.4%-99.3%) and a small German-speaking minority (most 10 or 1.6% in 1910), in terms of religion majority were Protestants (57% in 1910), followed by Roman Catholics (42.1% in 1910) and Jews (6 people).
