Contemporaries (including King Charles) and some in subsequent generations believed that Charles Louis' motive in visiting Roundhead London was that he hoped that Parliament would enthrone him in place of his uncle.
Kaasaegsed (sealhulgas kuningas Charles) ja mõned järgmistest põlvkondadest uskusid, et Karl Ludwigi motiiv Ümarpeade Londoni külastamiseks oli, et ta lootis, et parlament paneb ta oma onu asemel troonile.
