Saudi is a kingdom; Oman is a sultanate; the UAE is a federation of emirates. Qatar has an emir, but if you call it an emirate most people will say, "No, it's a state," which is odd because "state" is not a type of government.
Is there any real difference between an kingdom, a sultanate, and an emirate? Or are these just different words for the same thing? Obviously they have different etymologies, but is there any difference in the powers of their rulers?
I always thought there was some actual difference between the three forms of government, but here's how the CIA World Factbook defines them:

I always thought there was some actual difference between the three forms of government, but here's how the CIA World Factbook defines them:
- monarchy: "a government in which the supreme power is lodged in the hands of a monarch who reigns over a state or territory, usually for life and by hereditary right"
- sultanate: "similar to a monarchy, but a government in which the supreme power is in the hands of a sultan (the head of a Muslim state)"
- emirate: "similar to a monarchy or sultanate, but a government in which the supreme power is in the hands of an emir (the ruler of a Muslim state)."

I had thought, much as you say, that the emir is the head of a ruling family, whereas a sultan is more like a king in ruling personally. But I can't find evidence of that distinction anywhere.
Apart from it being both impolite and misleading in using a foreign name for the governmental system. If one uses Kindom one is tempted to assume the powers of the king are derived like and similar to (for example ) the British monarch - if One calls the Monarch Emperor this implies a King of Kings and an empire. Giving the monarchy the name 'emirate' makes one at least wonder what the power distribution is - how the current emir got to power; who does he need as support; who will become his successor
I think it was my Gulf history instructor who told me that nobody was entirely sure of the significance of the shift in titles beforehand. Afterwards, however, it became clear that the king had used it to cut back drastically on the number of royal family members dependent on the state. This was no small matter given the relative sizes of the country and its ruling family.
Here's the breakdown of their list:
- constitutional emirate: Kuwait
- constitutional monarchies: Antigua and Barbuda, Bahrain, Bhutan, Denmark, Jordan, Liechtenstein, Luxembourg, Malaysia, Monaco, Morocco, Netherlands, Norway, Sweden, Thailand, Tonga, United Kingdom
- constitutional sultanate: Brunei
- emirate: Qatar
- monarchies: Oman, Saudi Arabia, Swaziland
.(North Korea, for what it's worth, is listed as a "Communist state one-man dictatorship")
