Prince

What should a ruler do to get reputation and support when his kingdom is acquired with the forces of others and with good luck?

Go bribe his supporters – financial and military ones.

Yes, but that’s not enough. Since his reign does not come from the ordinary people, he could only gain their support (or avoid their fierce opposition) by bribing them. Giving out quick money is an easy way. Even if he has the vision, nothing would be done for long term benefit if there is short term compromise of the common people. The country would not prosper.

PS. Discerning visitors may notice the first sentence of this discussion sounds old and familiar.

Go read Niccolo Machiavelli’s The Prince.
