Masaesyli in the context of "Masinissa"

Numidia (Punic: 𐤌𐤌𐤋𐤊𐤕 𐤌𐤔𐤋𐤉𐤉𐤌, romanized: MMLKT MŠLYYM) was the ancient kingdom of the Numidians in northwest Africa, initially comprising the northern part of what is now Algeria, but later expanding into modern Tunisia and Libya. The polity was originally divided between the Massylii state in the east (Capital: Cirta) and the Masaesyli state in the west (Capital: Siga). During the Second Punic War (218–201 BC), Masinissa, king of the Massylii, defeated Syphax of the Masaesyli to unify Numidia into the first unified Berber state for Numidians in present-day Algeria. Initially a sovereign state and an ally of Rome, the kingdom later alternated between being a Roman province and a Roman client state.

Numidia, at its foundation, was bordered by the Moulouya River to the west, Africa Proconsularis and Cyrenaica to the east. the Mediterranean Sea to the north, and the Sahara to the south so that Numidia entirely surrounded Carthage except towards the sea. before Masinissa expanded past the Moulouya and vassalizing Bokkar, and reaching the Atlantic ocean to the west.

Mauretania (/ˌmɒrɪˈteɪniə, ˌmɔːrɪ-/; Classical Latin: [mau̯.reːˈt̪aː.ni.a]) is the Latin name for a region in the ancient Maghreb. It extended from central present-day Algeria to the Atlantic, encompassing northern present-day Morocco, and from the Mediterranean in the north to the Atlas Mountains. Its native inhabitants, of Berber ancestry, were known to the Romans as the Mauri and the Masaesyli.

In 25 BC, the kings of Mauretania became Roman vassals until about 44 AD, when the area was annexed to Rome and divided into two provinces: Mauretania Tingitana and Mauretania Caesariensis. Christianity spread there from the 3rd century onwards. After the Muslim Arabs subdued the region in the 7th century, Islam became the dominant religion.

The Massylii or Maesulians (Neo-Punic: 𐤌𐤔𐤋𐤉𐤉𐤌, MŠLYYM) were a Berber federation in eastern Numidia (central and eastern Algeria), which was formed by an amalgamation of smaller tribes during the 4th century BC. They were ruled by a king. On their loosely defined western frontier were the powerful Masaesyli. To their east lay the territory of the rich and powerful Carthaginian Republic. Their relationship to Carthage resembled that of a protectorate. Carthage maintained its dominance over the Massylii by skillful diplomatic manoeuvering, playing off local tribal and kingdom rivalries. The principal towns of the Massylii were Cirta, Tébessa and Thugga in modern-day Algeria and Tunisia.

Syphax (Ancient Greek: Σύφαξ, Sýphax; Punic: 𐤎𐤐𐤒, SPQ) was a king of the Masaesyli tribe of western Numidia (present-day Algeria) during the last quarter of the 3rd century BC. His story is told in Livy's Ab Urbe Condita (written c. 27–25 BC). He ruled over a territory extending from present day Constantine to Moulouya.
