The Plantagenet Alliance is a small grouping of individuals claiming to be descendants of the House of Plantagenet. The Alliance was formed in 2013 shortly after the discovery and identification of the remains of Richard III, the last Plantagenet king of England who died in 1485, in order to advance their views on the location of Richard's reburial. Reports of the number of members of the Alliance vary between fifteen and around forty.
The group campaigned to have Richard re-interred at York Minster, believing that, as his relatives, they knew his wishes. They referred to themselves as "his Majesty's representatives and voice". A campaign was launched in 2013, and their activities included initiating a judicial review of decisions taken by the Ministry of Justice relating to the proposed re-interment in Leicester. The Alliance lost the judicial review and the campaign to have Richard buried in York failed. He was interred in Leicester Cathedral on 26 March 2015.
In September 2012, an archaeological dig led by the University of Leicester resulted in the remains of Richard III, who was killed at the Battle of Bosworth Field in 1485, being discovered underneath a Council car park in Leicester. The Ministry of Justice announced in February 2013 that the University had the authority to determine the location of Richard’s reburial under the terms of the licence it had been granted to carry out the archaeological exhumation. The University of Leicester subsequently confirmed that it had always been its intention that the remains should be re-interred in Leicester Cathedral.
