In my world, because of how difficult the dark lord antagonist is to kill, he was permanently trapped in a weird substance. However, centuries later, he gets out and he is free. He awakens now in my world's equivalent to the 19th century, and he is from the 17th century. People are shocked that he is back and alive, and now he has to regain his kingdom. What would cause the people to allow him back into politics, even though he is a literal dark lord covered in armor? While this may be for one dark lord, this is meant to dark lords in general, because this happens a lot in the lore, but in different parts of the world. Notes to mention:

* He was originally from the Renaissance era, and is now in the Victorian era
* He was originally an absolute monarch, though now the kingdom is a constitutional monarchy
* The kingdom is based on the Ottoman Empire
* He cannot influence with "evil powers", because there is no such thing, his powers are mainly based around durability and near-immortality (he can live forever, but can get killed. Extremely difficult, but not impossible)
