The village was first mentioned in a Latin document of Diocese of Wrocław called Liber fundationis episcopatus Vratislaviensis from around 1305 as item in Goschegowitz debent esse XIII) mansi.[1][2][3] It meant that the village was supposed to pay a tithe from 13 greater lans. 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.
In the early 18th century they were subdivided into two separate villages: Kozakowice Małe (Klein Kozakowice, later Kozakowice Dolne) and Kozakowice Wielkie (Gros Kozakowice, later Kozakowice Górne).[4]
After Revolutions of 1848 in the Austrian Empire a modern municipal division was introduced in the re-established Austrian Silesia. Kozakowice as two separate municipalities were subscribed to the political district of Bielsko and the legal district of Skoczów. According to the censuses conducted in 1880, 1890, 1900 and 1910 the population Kozakowice Dolne grew from 217 in 1880 to 277 in 1910 and of Kozakowice Górne from 233 in 1880 to 276 in 1910. In both villages a majority of the inhabitants were native Polish-speakers (99.1%-100% in Kozakowice Dolne and 99.3%-100% in Kozakowice Górne; not more than 2 people speaking a different language), in terms of religion the majority were Protestants (in 1910 90.6 in Kozakowice Dolne and 82.6% in Kozakowice Górne), followed by Roman Catholics (in 1910 9.4% in Kozakowice Dolne and 17.4% in Kozakowice Górne).[5] The villages were also traditionally inhabited by Cieszyn Vlachs, speaking Cieszyn Silesian dialect.
