A good general history of Germany is the _Bibliothek deutscher Geschichte_, edited by H. von Zwiedeneck-Südenhorst (Stuttgart, 1876, fol.). Other general histories, although on a smaller scale, are K. Lamprecht, _Deutsche Geschichte_ (Berlin, 1891-1896); O. Kämmel, _Deutsche Geschichte_ (Dresden, 1889); K. Biedermann, _Deutsche Volks- und Kulturgeschichte_ (Wiesbaden, 1885); T. Lindner, _Geschichte des deutschen Volks_ (Stuttgart, 1894); the _Handbuch der deutschen Geschichte_, edited by B. Gebhardt (Stuttgart, 1901), and K. W. Nitzsch, _Geschichte des deutschen Volkes bis zum Augsburger Religionsfrieden_ (Leipzig, 1883-1885). Special reference is deservedly made to three works of the highest value. These are J. G. Droysen's great _Geschichte der preussischen Politik_ (Berlin, 1855-1886); the _Deutsche Reichstagsakten_, the first series of which was published at Munich (1867, fol.) and the second at Gotha (1893-1901); and the collection known as the _Regesta imperii_, which owes its existence to the labours of J. F. Böhmer. Nearly the whole of the period between 751 and 1347 is covered by these volumes; the charters and other documents of some of the German kings being edited by Böhmer himself, and new and enlarged editions of certain sections have been brought out by J. Ficker, E. Winkelmann and others. Much useful information on the history of different periods is contained in the lives of individual emperors and others. Among these are H. Prutz, _Kaiser Friedrich I._ (Danzig, 1871-1874); F. W. Schirrmacher, _Kaiser Friedrich II._ (Göttingen, 1859-1865); H. Ulmann, _Kaiser Maximilian I._ (Stuttgart, 1884-1891); F. von Hurter, _Geschichte Kaiser Ferdinands II._ (Schaffhausen, 1857-1864), and H. Blum, _Fürst Bismarck und seine Zeit_ (Munich, 1895). There is also the great series of volumes, primary and supplementary, forming the _Allgemeine deutsche Biographie_ (Leipzig, 1875, fol.), in which the word _deutsche_ is interpreted in the widest possible sense.
