De jure

In law and government, de jure (/deɪ ˈdʒʊəri, di -, - ˈjʊər-/; Latin: [deː ˈjuːre]; lit.

The phrase is often used in contrast with de facto ('in fact'), which describes situations that exist in reality, even if not formally recognized.

[2][3] In U.S. law, particularly after Brown v. Board of Education (1954), the difference between de facto segregation (that existed because of voluntary associations and neighborhoods) and de jure segregation (that existed because of local laws) became important distinctions for court-mandated remedial purposes.

However, starting from around 1882, the rulers had only de jure rule over Egypt, as it had by then become a British puppet state.

The de jure borders of a country are defined by the area its government claims, but not necessarily controls.
