The idea of citizenship is most usually encountered in the relationship between an individual and the sovereign state. For the vast majority of us, this relationship is with a single sovereign state; the number of people possessing dual nationality is very small and, indeed, a number of states refuse to countenance granting citizenship to an individual on anything other than an exclusive basis. Equally, the number of people who are citizens of no state is also small, thankfully so in most cases as being a stateless person can be a dangerous position, as well as an inconvenient one.
