What is a country with an aristocracy?

Answer 1

Technically, no countries are run by aristocracy. Aristocracy is present in many forms around the world and generally consists of honorific titles and governance over areas of land. However, even aristocrats have bosses and the supreme aristocrats are given supreme honorifics such as King, Caliph, Emperor etc. These countries are considered to be governed by 'Monarchy' not 'Aristocracy'. There are also places like India, the UK and Sweden where aristocratic tradition persists but the country is ruled by democracy.

Answer 2

In the broad sense, every country has an "aristocracy." most commonly this is the group presently controlling most of the wealth, which in places like Europe & the U.S. in modern times would (mostly) be/mean the business, banking, manufacturing people; but this can/does also include those with the abilities to govern and/or "charisma" to influence (the latter today evinced in the phenomenon of "celebrity" & its created "aristocracy"). If you mean today a country or nation that still maintains a separate privileged royal class like kings & queens and their considered relatives, England, Denmark, Holland, Japan & Saudi Arabia, to name a few. In most cases today this is mostly kept as part the country's historical tradition; the monarch & noble class being now essentially figureheads as part of a constitutional democratic government. In Saudi Arabia & a few other places, however, the monarch's/royals's still maintain themselves as a totally exclusive class with virtually absolute power, authority, wealth.
