Furioso II was imported to Germany by the legendary Oldenburg breeder, George Vorwerk (father of Gudula Vorwerk who currently stands a string of stallions, including - and until his recent death, Rubinstein). Furioso II was out of the great mare, Dame de Renville, who produced a series of wonderful horses when mated with Furioso. The first of these was Mexico, who standing at the French National Stud of Le Pin, sired 20 approved sons, 20 dams of stallions, and famous international showjumping horses, including Laeken, Jexico de Parc and Heur de Bratand. His son, Le Mexico, has been a hugely influential sire of jumping horses in Holland.

Furioso II was interesting to the Oldenburg breeders as they needed a half-blood stallion to help make the transformation of their mares to more modern lines, without too much direct Thoroughbred blood.
Furioso II was approved for the Oldenburg studbook in 1967, and then went on to easily win his 100 day test. Later he was approved for Hannover, Rhineland, Hessen and Westfalia. For many years, Furioso II was ranked in the top three sires of leading money winners in Germany. Furioso II had winners in all disciplines. His showjumping stars included: FBI (with Thomas Frhmann), Heissman (ridden by Eric Van Der Vleuten, then Michael Matz) and For Pleasure.

Heissman under his original name, Friesengeist was sold to the stables of Henk Nooren, who later sold him to the United States, when ridden by Michael Matz he was Horse of the Year, and 4th at the Barcelona Olympics.

For Pleasure was originally ridden by Lars Nieberg, and under his guidance won team gold at Atlanta, before the ride was transferred to Marcus Ehnning. For Pleasure is already the sire of eight licensed Hanoverian stallions, and was a member of the gold medal winning German team at the Sydney Olympic Games.

Perhaps Furioso IIs most influential son is Voltaire - out of a mare by another classic sire of jumping horses, Gotthard. Voltaire is the sire of 33 approved sons and top jumpers like Finesse and Altaire.
In dressage, his son, Purioso is the sire of numerous stars including Anky van Grunsvens Grand Prix horse Cocktail (who is the sire of Jazz); Le Mexico is the sire of Ulft, who in turn is the sire of Ferro. The Oldenburg stallion Welt As is out of a Furioso II daughter, and is the sire of Ankys gold medallist Bonfire and Christine Stckelbergers Grand Prix horse, STC Diamond.
