Kugler's Geschichte der Kreuzziige (in Oncken's series) still remains a suggestive and valuable work; and L.
Oncken's Lassalle (Stuttgart, 1904); another excellent work on his life and writings is George Brandes's Danish work, Ferdinand Lassalle (German translation, 4th ed., Leipzig, 1900).
Then turning to a wider theme Prutz contributed to Oncken's university history the two volumes on the political history of Europe during the middle ages (Staatengeschichte des Abendlandes im Mittelalter, Berlin, 1885-1887).
Thus the great enterprises of to-day are co-operative - the Cambridge Modern History, Lavisse and Rambaud's Histoire generale, or Lavisse's Histoire de France, like Hunt and Poole's Political History of England, and Oncken's Allgemeine Geschichte in Einzeldarstellungen.
