Known for military leadership? Very doubtful
Well known in UK? Reply hazy try again
Dead male non-P European politician? Signs point to yes.

Died after 1900? Without a doubt.

All right. Reluctantly I think I need to abandon the 8-ball, or I risk confusing and infuriating you all.
Die after 2000? No.
Francophone? I can't tell from the sources I have checked. French was not his mother tongue, but there are some reasons to believe he may at least have had a working knowledge of the language.
Well-known in the UK? Concentrate and ask again. Oh, sorry. I do not think that, at the present time, you would say that. But the abstract connection is at least somewhat well-known.

Quisling? It is decidedly so! An impressive leap there. The answer is indeed Vidkun Quisling, leader of the Norwegian collaborationist government from 1942-45. Tuj asked the wrong question. One baton inscribed "with best wishes, Adolf" handed over.

Yes, well, sometimes an answer just jumps into your head and you have to take a guess.
This next one is ABSTRACT with ANIMAL connections

[Software] human animal? - YES is probably the most helpful answer

(The next question is: "Is this person in the arts and entertainment professions?")

[CdM] Fictional - YES
The next answer is NO

Actually, the best answer to Software would have been YESish and NO

[Chalky] 'well, sometimes an answer just jumps into your head and you have to take a guess' - this one happens to be wrong

[Phil] Godlike animal? - NO *a couple of audience members exchange significant glances*

[Tuj] R-start? - NO
[Quen] Proverb? - Not as such but *some applause*
[CdM] Just the one? YES and NO
[Phil] Mythical? - YES and NO
[Raak] Aslan? - NO

[Software] Grauniad Angle? - NO

[Phil] Character in book? - The human animal appears in at least one literary work.

[Chalky] I say, I say, I say? - NO
[Tuj] >1 creature? - YES! *relieved applause*
