Law of Blood

(redirected from Ius Sanguinis)

Law of Blood

A citizenship law stating that all or nearly all persons born to citizens of a given state are themselves citizen of that state, regardless of where they were born. For example, one with a parent who has been a U.S. citizen for one year is a citizen of the U.S., regardless of where one was born. Some countries (including the United States) also follow the law of the soil in addition to the law of blood.

Nowadays, most countries do not apply either ius sanguinis or ius soli, but a combination of both principles.
It is important to realise, that already the choice for a certain application of ius soli/ ius sanguinis implies an unequal competition of States in respect of sports(wo)men and unequal opportunities for athletes.
But in fact, if States do not apply ius soli or make exceptions regarding ius sanguinis this is often to some extent compensated by facilitated access to the nationality.
Insistence on ius sanguinis in identifying citizenship eligibility means that generations of immigrant descendants, eligible for citizenship according to ius soli, are uprooted from their countries of origin and marginalized in the societies where they were born.
