Inlaw and government, de jure (/deɪ ˈdʒʊəri, di -, - ˈjʊər-/, Latin: [deː ˈjuːre]; lit. 'by law') describes practices that are legally recognized, regardless of whether the practice exists in reality.[1] In contrast, de facto ('in fact') describes situations that exist in reality, even if not formally recognized.[2]
Between 1805 and 1914, the ruling dynastyofEgypt were subject to the rulers of the Ottoman Empire, but acted as de facto independent rulers who maintained a polite fiction of Ottoman suzerainty. However, starting from around 1882, the rulers had only de jure rule over Egypt, as it had by then become a British puppet state.[3] Thus, by Ottoman law, Egypt was de jure a province of the Ottoman Empire, but de facto was part of the British Empire.
InU.S. law, particularly after Brown v. Board of Education (1954), the difference between de facto segregation (segregation that existed because of the voluntary associations and neighborhoods) and de jure segregation (segregation that existed because of local laws that mandated the segregation) became important distinctions for court-mandated remedial purposes.[4]
