In addition certain relatives of the monarch (by blood or marriage) possess special privileges and are subject to certain statutes, conventions, or special common law. The precise functions of a royal family vary depending on whether the polity in question is an absolute monarchy, a constitutional monarchy, or somewhere in between. In certain monarchies, such as that found in Saudi Arabia or Kuwait, or in political systems where the monarch actually exercises executive power, such as in Jordan, it is not uncommon for the members of a royal family to hold important government posts or military commands. In most constitutional monarchies, however, members of a royal family perform certain public, social, or ceremonial functions, but refrain from any involvement in electoral politics or the actual governance of the country.
The specific composition of royal families varies from country to country, as do the titles and royal and noble styles held by members of the family. The composition of the royal family may be regulated by statute enacted by the legislature (e.g. Spain, the Netherlands, and Japan since 1947), the Sovereign's prerogative and common law tradition (e.g. the United Kingdom), or a private house law (e.g., Liechtenstein, the former ruling houses of Bavaria, Prussia, Hanover, etc.). Public statutes, constitutional provisions, or conventions may also regulate the marriages, names, and personal titles of royal family members. The members of a royal family may or may not have a surname or dynastic name.
In a constitutional monarchy, when the monarch dies, there is always a law or tradition of succession to the throne that either specifies a formula for identifying the precise order of succession among family members in line to the throne or specifies a process by which a family member is chosen to inherit the crown. Usually in the former case the exact line of hereditary succession among royal individuals may be identified at any given moment during prior reigns (e.g. United Kingdom, Sark, Nizari Ismailis, Japan, Balobedus, Sweden, Benin Empire) whereas in the latter case the next sovereign may be selected (or changed) only during the reign or shortly after the demise of the immediately preceding monarch (e.g. Cambodia, KwaZulu Natal, Buganda, Saudi Arabia, Swaziland, Yorubaland, The Kingitanga). Some monarchies employ a mix of these selection processes (Malaysia, Monaco, Tonga, Jordan, Morocco), providing for both an identifiable line of succession as well as authority for the monarch, dynasty or other institution to alter the line in specific instances without changing the general law of succession.
Some countries have abolished royalty altogether, as in post-revolutionary France and Russia.
