History
Around the year 1000 the Counts of Calw had a fortress built near today's village of Neuenbürg-Dennach. The fortress was called Straubenhardt after the inhospitable area. The castellan soon took on the name of the fortress. Starting 1320 the castle and its surrounding areas came increasingly under the domination of the House of Württemberg. The Schmalensteiners who were related by marriage to the Lords of Straubenhardt and who also lived at the fortress, therefore joined a Federation of the Knights under the leadership of Wolf von Eberstein. In 1367 the Federation of the Knights committed an assault on Count Eberhard II of Württemberg while he was staying in Wildbad. It is not clear whether this happened at the present Bad Wildbad or at Bad Teinach. However, the description of his escape route indicated that it indeed happened at today's Bad Wildbad. The Count was able to flee to the fortress Zavelstein. In retaliation, and due to further differences, Count Eberhard II occupied the fortress Straubenhardt sometime between 1374 and 1381 and had it destroyed. After the destruction of their fortress the nobles of Straubenhardt moved their residence to Schwann and built a castle there. Schwann was the center of an administrative district and jurisdiction of the nobles of Straubenhardt and the family of Schmalenstein. The family Straubenhardt became extinct in 1442 and the sovereignty of the properties slowly moved towards Württemberg and Baden. It is suspected that the nobles of Straubenhardt initiated the foundation of the villages Conweiler, Feldrennach, Langenalb, Schwann as well as Arnbach, Dennach, Dobel, Neusatz and Rotensol. The discovery of a relief of the hunting goddess Diana, found in the wall of the rectory of Ottenhausen, indicates an early Roman settlement in this area. Ottenhausen which consists of the older village Rudmersbach and the newer part Ottenhausen was first documentary mentioned in 1262 with the name 'Rutmerspach'. Pfinzweiler which was mentioned in 1328 as hamlet 'uff dr Pfinz' was abandoned during the Thirty Years' War. The reestablishment of Pfinzweiler in 1713 can be traced back to 7 citizens of Feldrennach and one person from Conweiler. On December 1, 1973, today's municipality Straubenhardt was created by the merger of the municipalities Conweiler, Schwann, Pfinzweiler-Feldrennach. On January 1, 1974 Ottenhausen joined Straubenhardt by a voluntary agreement and on January 1, 1975 Langenalb was incorporated by the order of the Baden-Wuerttemberg Municipal Reform Act. By nomenclature and adoption of the Straubenhardt coat of arms the historical connection to the earlier nobles of Straubenhardt was restored.
