Good call on all of those, Rufus Here are a few of mine:-

Jan Hus - an early critic of the abuses of the Roman church who died for his beliefs, but whose beliefs lived on after his death and inspired.....

....Jan Zizka - a superb military thinker who shaped an armed gang into a fighting force that was more than a match for any army that stood against it, and that only suffered ultimate downfall due to internal divisions.

Joan of Arc - arguably a mere figurehead but who persuaded the French that the English were beatable.

Ferdinand and Isabella - the 'Catholic Kings' who united Spain - completed the Reconquista, and then translated that fanaticism into the foundations of an Empire that lasted into the last century.

Owain Glyndwr - for giving us Welsh a last decent stab at nationhood
