The 1994 Ethiopian constitution creates a unique federal state. Its preamble declares:

The constitution goes on to reconstruct Ethiopia as a federation wherein ‘all sovereign power resides’, not in the people of Ethiopia but among its many, diverse ‘nations, nationalities and peoples’. No distinction is made between a nation and a people. Both are defined as a group sharing a common language, culture, customs, history and identity. All such groups are endowed with a corporate right to constitute themselves into a self-governing state or local government within a state. Each enjoys an unconditional right to self-determination, including the right to secession (articles 8 and 39).

In contrast, the preamble to the 1997 constitution of Eritrea – once a territory of the Ethiopian empire, but now (through force of arms and unilateral invocation of self-determination) Africa's newest independent state – declares:

The constitution recognises Eritrea's notable ethnic, regional and religious pluralism, but it tells us that these peoples, as a result of their collective exercise of self-determination, are now a single nation ‘guided by the principle of unity in diversity’ (preamble and art. 6).
