History
The village was established in the early 14th century shortly after the foundation of Bielsko. It was first mentioned in 1312 in the document of Mieszko I, Duke of Cieszyn in which the duke bestowed the forest between Kamienica and Mikuszowice upon the town dwellers of Bielsko. Being then mentioned as Nickelstorff, the name being an amalgam of Nicholas in German spelling and dorf, it was undoubtedly established by German settlers. In 1314 or 1315 in the process of feudal fragmentation of Poland the Duchy of Oświęcim was split from the Duchy of Teschen with the new border running along Biała River and cutting through Mikuszowice, dividing it into two parts.
The part of the village on the left bank of the Biała river continued to be a part of the Duchy of Teschen, which like the Duchy of Oświęcim in 1327 also became a fee of the Kingdom of Bohemia. However, when the Duchy of Oświęcim became a part of Poland in the 1450s, the Duchy of Teschen continued to be a part of the Kingdom of Bohemia, which itself became a part of the Habsburg Monarchy in 1526. Biała River constituted then a state border. In 1572 Mikuszowice Śląskie were sold together with Bielsko and dozen surrounding villages by dukes of Teschen and formed Bielsko state country. In the middle of the 17th century Stanisław Warszycki, the owner of Mikuszowice Krakowskie occupied the Silesian counterpart of the village, which led to an intervention of the Habsburg army in 1655. A year later the village was assaulted by Swedish army in the course of the so called Deluge, local peasants failed to defend themselves, and both villages were burned on 8 March. After the Revolutions of 1848 in the Austrian Empire a modern municipal division was introduced in the re-established Austrian Silesia. The village as a municipality was subscribed to the political and legal district of Bielsko. According to the censuses conducted in 1880, 1890, 1900 and 1910 the population of the municipality grew from 809 in 1880 to 1502 in 1910 with the majority being native German-speakers accompanied by Polish-speaking minority. In terms of religion in 1910 the majority were Roman Catholics, followed by Protestants, Jews and 3 others. It was then considered to be a part of a German language island around Bielsko. In the late 19th century Mikuszowice Śląskie became a spa resort for Bielsko residents, in contradistinction to the more industrialized Mikuszowice Krakowskie.
After the division of Cieszyn Silesia in 1920 Mikuszowice Śląskie also became a part of Poland. The villages were then administratively joined. The municipality was annexed by Nazi Germanyat the beginning of World War II, after it they were restored to Poland. Afterwards they were intermittently separated. In 1957 Mikuszowice Śląskie gained a status of urban-type settlement. Mikuszowice became administratively a part of Bielsko-Biała in 1968.
