Numidia (202 BC – 46 BCE) is an ancient Berber kingdom in modern day Algeria and a part of West Tunisia in North Africa.

Numidia was originally divided between Massyliis in Eastern Numidia with Massinissa and Masaesylis in Western Numidia diriged by Syphax.

It is Massinissa who historically won over Syphax and unifed Numidia into one kingdom.

The kingdom begins as a sovereign state and later alternates between being a Roman province and being a Roman client state.

The kingdom is located on the eastern border of modern Algeria, bordered by the kingdoms of Mauretania (modern-day Morocco ) to the west, the Roman province of Africa (modern-day Tunisia) to the east, the Mediterranean Sea to the north, and the Sahara Desert to the south.

Its people are the Numidian Berbers.

It is considered to be the first major state in the history of Algeria.
