Descendants of some 20 families who fought at the Battle of Bosworth, that ended the reign of Richard III, are to meet for the first time.
Researchers who identified the king using DNA from his distant family used the same techniques to find descendants of those who fought in the battle.
They will meet family members directly related to the last Plantagenet king at a reception in Leicester later.
Some have flown from Australia, South Africa and Canada for the occasion.
Richard, the last English king to die in battle, was killed at Bosworth Field in 1485, at the end of the Wars of the Roses.
