his sons passed to the clergy and do not appear in genealogy records due to compulsory celibacy associated with the clergy. Soltan/Soldan's descendants, who were more widespread in south-west Germany, include notable German artists, scholars, doctors, lawyers and politicians. For example, through his maternal grandmother, the renowned German poet and writer Johann Wolfgang von Goethe belonged to the descendants of the Soldan family and thus had Turkish ancestry. Bernt Engelmann has said that "the German poet prince [i.e. Goethe] with oriental ancestors is by no means a rare exception." Indeed, other descendants of the first recorded Turk in Germany include the lawyer ; the city architects and wine masters Heinrich Soldan and his son Johann Soldan who both served as Mayor of Frankenberg; the sculptor and artist ; and the pharmacist Carl Soldan who founded the confectionery company "". Carl Soldan's grandson, Pery Soldan, has said that the family continue to use the crescent and star on their coat of arms. According to Latif Çelik, as of 2008, the Soldan family numbered 2,500 and are also found in Austria, Finland, France and Switzerland. Turkish migration from the Ottoman Empire The Turkish people had greater contact with the German states by the sixteenth century when the Ottoman Empire attempted to expand their territories beyond the north Balkan territories. The Ottoman Turks held two sieges in Vienna: the first Siege of Vienna in 1529 and the Second Siege of Vienna in 1683. The aftermath of the second siege provided the circumstances for a Turkish community to permanently settle in Germany. Many Ottoman soldiers and camp followers who were left behind after the second siege of Vienna became stragglers or prisoners. It is estimated that at least 500 Turkish prisoners were forcibly settled in Germany. Historical records show that some Turks became traders or took up other professions, particularly in southern Germany. Some Turks fared very well in Germany; for example, one Ottoman Turk is recorded to have been raised to the Hanoverian nobility. Historical records also show that many Ottoman Turks converted to Christianity and became priests or pastors. The aftermath of the second siege of Vienna led to a series of wars between the Ottoman Empire and the Holy League, known as the "Great Turkish War", or the "War of the Holy League", which led to a series of Ottoman defeats. Consequently, more Turks were taken by the Europeans as prisoners.
