Oldřichovice (Třinec)

[2] The settlement was first mentioned in a Latin document of Diocese of Wrocław called Liber fundationis episcopatus Vratislaviensis from around 1305 as item in Ulrici villa.

The creation of the village was a part of a larger settlement campaign taking place in the late 13th century on the territory of what will be later known as Upper Silesia.

Politically the village belonged initially 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.

According to the censuses conducted in 1880, 1890, 1900 and 1910 the population of the municipality grew from 1,574 in 1880 to 2,009 in 1910 with a majority being native Polish-speakers (growing from 98.7% in 1880 to 98.8% in 1900 then dropping to 96.1% in 1910) accompanied by German-speaking (at most 57 or 2.8% in 1910) and Czech-speaking people (at most 21 or 1.1% in 1910).

Following the Munich Agreement, in October 1938 together with the Zaolzie region it was annexed by Poland, administratively adjoined to Cieszyn County of Silesian Voivodeship.
