Eritrean - Ethiopian War
Eritrea x Ethiopia conflict has taken place in the last 20 years in East Africa. It started in May 1998 and "ended" in June 2000, but only in 2018 the Peace Agreement was officially signed. A few years before this conflict, both countries had been fighting a long 30 years war where Eritrea demanded Independence from Ethiopia. However, following peaceful separation in 1993, both countries disagreed over trade, territory and currency issues which led to the second conflict (Eritrean-Ethiopian War).
The Bill of Rights was the 10 proposed amendments intended to protect citizens rights.
