the two most notable societies of ricardians are the richard iii society, and the richard iii foundation, inc. a third much smaller ricardian organisation, composed of "collateral descendants" of richard iii, is the plantagenet alliance. in 2012 the richard iii society was instrumental in leading an archaeological effort to positively locate and identify the long-lost remains of richard iii, which resulted in the discovery and retrieval of the remains from beneath a leicester car park. subsequently, much popular historical interest was generated in this historical period. such historical interest resulted in the review and publication of many articles and documents regarding richard's reign, which have contributed to the scholarship of latter 15th-century england. after their discovery, richard iii's remains were first scientifically evaluated, then formally re-interred within the interior of leicester cathedral on 26 march 2015. their re-interment occurred amidst days of solemn ceremonies and pageantry.
