Chapter 0 lists 'unique politicians, state-founding brave warriors, extraordinary jurists' as types of worldly Gurus. Can you give me the names of the specific politicians or warriors the author considered to be examples of this?

While the preface in Chapter 0 does indeed categorize individuals like 'unique politicians, state-founding brave warriors, extraordinary jurists' as worldly Gurus to whom one can offer service by writing their biographies, the provided text does not name any specific historical figures as examples. The author discusses this type of Guru service in a general sense to contrast it with the more spiritually fruitful service of writing a saint's biography, but does not offer concrete examples of who these worldly Gurus might be.
