Rebellions
Throughout the history of the wizarding world there have been rebellions where the goblins have fought against the discrimination and prejudice. These goblin rebellions were most prevalent in the 1600s and 1700s, but even today there are subversive goblin groups who work in secret against the Ministry, according to the Daily Prophet. One rebellion, in 1612, took place in the vicinity of Hogsmeade, the Inn there was used as headquarters for the rebellion. The rebellions have been described as "bloody and vicious." The names of the rebels tend to run along the lines of "Bodrod the Bearded and Urg the Unclean," according to Ron

Clevernes
Goblins are extremely clever and over the years have dealt with wizard-kind effectively. They are still subservient in the minds of most wizards, but they have established themselves as a vital part of wizarding society. The goblins run Gringotts, the wizarding bank. Therefore, they control the wizarding economy to a large extent. There are rumors, almost certainly unfounded, that Cornelius Fudge is plotting ways to take over control of the money supply and the economy from the goblins.

Apart from their cleverness with money and finances, goblins are also very capable metalsmiths. Their silverwork is well known and prized (Sirius Black's wealthy family had dishes which were 'finest fifteenth-century goblin-wrought silver, embossed with the Black family crest'. when Hagrid visited the Giants, one of the presents he brought was a goblin-wrought helmet which was described as "indestructable" . Goblins actually mint the Galleons, Sickles, and Knuts used in the wizarding world; each coin is stamped with a serial number identifying the goblin who cast it.

Which Side
The goblins suffered their share of losses during the first rise of Voldemort to power in the 1970s. A family living near Nottingham had been murdered by Voldemort's followers at that time, and Bill Weasley has been approaching the goblins, appealing to their sense of belonging to the Wizarding community. This is proving problematic, however, because a Ministry official, Ludo Bagman, swindled a group of goblins out of a large amount of gold at the Quidditch World Cup in the summer of 1995
