Závada (Polish: Zawadaⓘ) is a village and administrative part of Petrovice u Karviné in Karviná District, Moravian-Silesian Region, Czech Republic.
The name of the village is of Slavic topographic or cultural origins denoting "a natural or artificial obstacle".
[1] Politically the village belonged initially to the Duchy of Teschen, a fee of the Kingdom of Bohemia, which after 1526 became a part of the Habsburg monarchy.
In terms of the dominant language spoken colloquially the majority were Polish-speakers (between 95.1% and 96.3%), accompanied by German-speakers (at most 4.7% in 1880), and by Czech-speakers (at most 5 or 0.9% in 1910).
Following the Munich Agreement, in October 1938 together with the Trans-Olza region it was annexed by Poland, administratively organised in Frysztat County of Silesian Voivodeship.
