In April 1469 parts of the north rose in rebellion against Edward IV. John Neville, the Earl of Northumberland – the Percy family having been displaced for a time – put down the rebellion killing Robin, if Polydore Vergil is to be believed. A second leader took on Robin’s authority and name and the rebellion continued. it’s worth pointing out that John was the Kingmaker’s brother and that the Kingmaker, a.k.a the Earl of Warwick, orchestrated the uprising. Amongst the rebels demands was the removal of the Woodville family from power.
The real identity of Robin is unknown. He may have been Sir John Conyers or his brother William. Sir John was Middelham’s steward, related by marriage to the Nevilles and would fight alongside the kingmaker at the Battle of Edgecote in July 1469. Conyers was one of the casualties of the battle. Equally, it seems unlikely that Warwick’s brother would put down a rebellion fermented by the Kingmaker. An alternative source for the uprising might be the Percy family who had suffered a serious setback at Towton when their rivals the Nevilles emerged victorious and the Lancastrian king was toppled from power. The north became a Neville stronghold and in 1464 Neville became the Earl of Northumberland – which did not go down well with the locals. It should also be added that the rebels weren’t keen on the tax situation. None-the-Less the Warkwarth Chronicle places the blame for the rebellion squarely on the shoulders of Warwick.
Part of the problem in terms of understanding the rebellion, or even rebellions, and its participants is that the chronicles are often written at a later date and/or by writers living in the south. The Croyland Chronicler was not a fan of anyone who lived north of the River Trent – which isn’t even the north in He-who-is-occasionally-obeyed’s opinion but then he comes from Cumbria and most of the country is the south so far as he’s concerned. The other problem is that there’s no record of trials – there is a set of records sent to Calais (remember Warwick was the Captain of Calais)
