EAC Bloc Recognition
Swahili ranks as one of three official languages (with English, French) for the EAC, covering eight nations: Burundi, DRC, Kenya, Rwanda, Somalia, South Sudan, Tanzania, Uganda. This enables parliamentary use, trade standardization, and cross-border education, though implementation varies—Rwanda emphasizes Kinyarwanda primarily, Somalia uses it regionally.
Other Recognized Areas
-
Rwanda/Burundi: National working language in EAC contexts; school subject.
-
Mozambique: Official minority language in north (Mwani dialect).
-
Comoros: Comorian dialect (Shingazija) nationally official.
Tanzania uniquely mandates Swahili exclusively for unity post-independence, unlike multilingual peers
