No. What seems to be three separate entities;
Benin
Republic of Benin and
Peoples Repuplic of Benin
are all the same place, the nation that used to be Dahomey.
Dahomey is, interestingly, the last African Nation that bought
slaves from other nations and sold them to Portugese traders. The
loss of the slave trade was a brutal blow to the economy of
Dahomey, from which it may never recover.
