5-3P7 was a protocol droid, who was owned by a noble. 5-3P7 noticed that the noble was treating his droids cruelly, so the protocol droid united the noble's droids, as well as the droids of other nobles, to form the Idle. The droids all stopped working and the nobles responded by destroying or deactivating a number of the droids. 5-3P7 was one of the first to be deactivated, but the movement was eventually successful and the noble agreed to treat his droids better.
