its lands and castle passing to the Öhringen-Neuenstein branch (sold in 1952), but the branches of Hohenlohe-Langenburg (residing at Langenburg Castle) and Hohenlohe-Ingelfingen still exist, the latter being divided into Hohenlohe-Ingelfingen-Öhringen (which became extinct in 1960) and Hohenlohe-Oehringen (today residing at Neuenstein Castle). The two actual heads of the branches of Langenburg and Oehringen are traditionally styled Fürst. Frederick Louis, Prince of Hohenlohe-Ingelfingen, had acquired the estates of Slawentzitz, Ujest and Bitschin in Silesia by marriage in 1782, an area of 108 square miles, where his grandson Hugo zu Hohenlohe-Öhringen, Duke of Ujest, established calamine mines and founded one of the largest zinc smelting plants in the world. His son, prince Christian Kraft (1848-1926), sold the plants and went almost bankrupt with a fund in which he had invested in 1913; the mines he had still kept were, however, divided between Germany and Poland, together with Upper Silesia, in 1922, and in 1945 were depropriated by communist Poland. The Roman Catholic branch of Hohenlohe-Waldenburg was soon divided into three side branches, but two of these had died out by 1729. The surviving branch, that of Schillingsfürst, was divided into the lines of Hohenlohe-Schillingsfürst and Hohenlohe-Bartenstein, with further divisions following. The four catholic lines which still exist today (with their heads styled Fürst) are those of Hohenlohe-Schillingsfürst (at Schillingsfürst), Hohenlohe-Waldenburg-Schillingsfürst (at Waldenburg), Hohenlohe-Jagstberg (at Haltenbergstetten) and Hohenlohe-Bartenstein (at Bartenstein). A side branch of the House of Hohenlohe-Schillingsfürst inherited the dukedom of Ratibor in Silesia in 1834, together with the principality of Corvey in Westphalia. While the Silesian property was expropriated in Poland in 1945, Corvey Abbey remains owned by the Duke of Ratibor to this day, together with further inherited properties in Austria. The Holy Roman Emperors granted the title of Imperial Prince (Reichsfürst) to the Waldenburg line (in 1744) and to the Neuenstein (Öhringen) line (in 1764). In 1757, the Holy Roman Emperor elevated possessions of the Waldenburg line to the status of Imperial Principality. In 1772, the Holy Roman Emperor elevated possessions of the Neuenstein and Langenburg lines to the status of Imperial Principality. On 12 July 1806, the principalities became parts of the kingdoms of Bavaria and of Württemberg by the Act of the Confederation of the Rhine. Therefore, the region of Hohenlohe is presently located for the most part in the north eastern part of the State of Baden-Württemberg (forming the counties of Hohenlohe, Schwäbisch Hall and
