Tarnawa has a long history, dating back to the Middle Ages. From its earliest days until the end of the 17th century, it was owned by various families of the Drużyna coat of arms, including the great Lubomirski house. It was the home of the wooden parish church under the invocation of Blessed Virgin Mary, temporary changed into a Calvinist congregation. In the following years, Tarnawa became a part of the Wiśnicki demesne, passing into the hands of various representatives of side branches of the Lubomirski family, as well as the Sanguszko and Potocki families. In the 19th century, it was bought by the Marynowski family, who were severely affected by the Galician Slaughter of 1846. After them, the estate was taken over by the Brunicki barons, creating the so-called Gierczyce Dominion. Then, until the outbreak of World War I, the estate was held by the Radomyski family of the Rogala coat of arms. The 20th century was for Tarnawa a time of constant struggle with the issue of agricultural reform and division of the property of landowners, endless friction with the Stojowski heirs and involvement of local residents in the peasant movement.
