Client state in the context of "Wars of Augustus"

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.

A colony is a territory subject to a form of foreign rule, which rules the territory and its indigenous peoples separated from the foreign rulers, the colonizer, and their metropole (or "mother country"). This separated rule was often organized into colonial empires, with their metropoles at their centers, making colonies neither annexed or even integrated territories, nor client states. Particularly new imperialism and its colonialism advanced this separated rule and its lasting coloniality. Colonies were most often set up and colonized for exploitation and possibly settlement by colonists.

The term colony originates from the ancient Roman colonia, a type of Roman settlement. Derived from colonus (farmer, cultivator, planter, or settler), it carries with it the sense of 'farm' and 'landed estate'.Furthermore, the term was used to refer to the older Greek apoikia (Ancient Greek: ἀποικία, lit. 'home away from home'), which were overseas settlements by ancient Greek city-states. The city that founded such a settlement became known as its metropolis ("mother-city"). Since early-modern times, historians, administrators, and political scientists have generally used the term "colony" to refer mainly to the many different overseas territories of particularly European states between the 15th and 20th centuries CE, with colonialism and decolonization as corresponding phenomena.

The Herodian tetrarchy was a regional division of a client state of Rome, formed following the death of Herod the Great in 4 BCE. The client kingdom was divided between Herod's sister Salome I and his sons Herod Archelaus, Herod Antipas, and Philip. Upon the deposition of Herod Archelaus in 6 CE, his territories were transformed into a Roman province. With the death of Salome I in 10 CE, her domain was also incorporated into a province.

Other parts of the Herodian tetrarchy continued to function under Herodians. Philip ruled over territories north and east of the Jordan River until 34 CE. His domain was later incorporated into the Province of Syria. Herod Antipas ruled Galilee and Perea until 39 CE. The last notable Herodian ruler with some level of independence was King Herod Agrippa I. He was given the territory of Judea with its capital Jerusalem. With his death in 44 CE, the provincial status of Judea was restored for good.

The Tripartite Pact, also known as the Berlin Pact, was an agreement between Germany, Italy, and Japan signed in Berlin on 27 September 1940 by, respectively, Joachim von Ribbentrop, Galeazzo Ciano, and Saburō Kurusu (in that order) and in the presence of Adolf Hitler. It was a defensive military alliance that was eventually joined by Hungary (20 November 1940), Romania (23 November 1940), Slovakia (24 November 1940), Bulgaria (1 March 1941), and Yugoslavia (25 March 1941). Yugoslavia's accession provoked a coup d'état in Belgrade two days later. Germany, Italy, and Hungary responded by invading Yugoslavia. The resulting Italo-German client state, known as the Independent State of Croatia, joined the pact on 15 June 1941.

The Tripartite Pact was, together with the Anti-Comintern Pact and the Pact of Steel, one of a number of agreements between Germany, Japan, Italy, and other countries of the Axis powers governing their relationship.

A vassal state is any state that has a mutual obligation to a superior state or empire, in a status similar to that of a vassal in the feudal system in medieval Europe. Vassal states were common among the empires of the Near East, dating back to the era of the Egyptian, Hittite, and Mitanni conflict, as well as in ancient China.

The relationships between vassal rulers and empires were dependent upon the policies and agreements of each empire. While the payment of tribute and military service was common amongst vassal states, the degree of independence and benefits given to vassal states varied. Today, more common terms are puppet state, protectorate, client state, associated state, or satellite state.

The Principality of Bulgaria (Bulgarian: Княжество България, romanized: Knyazhestvo Balgariya) was a vassal state under the suzerainty of the Ottoman Empire. It was established by the Treaty of Berlin in 1878.

After the Russo-Turkish War ended with a Russian victory, the Treaty of San Stefano was signed by Russia and the Ottoman Empire on 3 March 1878. Under this, a large Bulgarian vassal state was agreed to, which was significantly larger: its lands encompassed nearly all ethnic Bulgarians in the Balkans, and included most of Moesia, Thrace and Macedonia, stretching from the Black Sea to the Aegean. However, the United Kingdom and Austria-Hungary were against the establishment of such a large Russian client state in the Balkans, fearing it would shift the balance of power in the Mediterranean. Due to this, the great powers convened and signed the Treaty of Berlin, superseding the Treaty of San Stefano, which never went into effect. This created a much smaller principality, alongside an autonomous Eastern Rumelia within the Ottoman Empire.

The first government of ancient Macedonia was established by the Argead dynasty of Macedonian kings during the Archaic period (8th–5th centuries BC). The early history of the ancient kingdom of Macedonia is obscure because of shortcomings in the historical record; little is known of governmental institutions before the reign of Philip II during the late Classical period (480–336 BC). These bureaucratic organizations evolved in complexity under his successor Alexander the Great and the subsequent Antipatrid and Antigonid dynasties of Hellenistic Greece (336–146 BC). Following the Roman victory in the Third Macedonian War over Perseus of Macedon in 168 BC, the Macedonian monarchy was abolished and replaced by four client state republics. After a brief revival of the monarchy in 150–148 BC, the Fourth Macedonian War resulted in another Roman victory and the establishment of the Roman province of Macedonia.

It is unclear if there was a formally established constitution dictating the laws, organization, and divisions of power in ancient Macedonia's government, although some tangential evidence suggests this. The king (basileus) served as the head of state and was assisted by his noble companions and royal pages. Kings served as the chief judges of the kingdom, although little is known about Macedonia's judiciary. The kings were also expected to serve as high priests of the nation, using their wealth to sponsor various religious cults. The Macedonian kings had command over certain natural resources such as gold from mining and timber from logging. The right to mint gold, silver, and bronze coins was shared by the central and local governments.

The Cisalpine Republic (Italian: Repubblica Cisalpina; Lombard: Republica Cisalpina) was a sister republic or a client state of France in Northern Italy that existed from 1797 to 1799, with a second version until 1802.

The reign of Cleopatra VII of the Ptolemaic Kingdom of Egypt began with the death of her father, Ptolemy XII Auletes, by March 51 BC. It ended with her suicide in August 30 BC, which also marked the conclusion of the Hellenistic period and the annexation of Egypt into a Roman province. In the style of her Greek predecessors, Cleopatra reigned over Egypt and other territories as an absolute monarch, although the Roman Republic frequently interfered in its internal affairs. Her personal rule of Egypt was characterized by a continued reliance on agriculture, extensive trade and conflict with other states, the tackling of corruption, strategic management of the bureaucracy, and ambitious building projects.

Cleopatra initially acceded to the throne alongside her younger brother Ptolemy XIII, but a fallout between them led to open civil war. Further chaos ensued when the Roman consul Julius Caesar pursued his rival Pompey into Ptolemaic Egypt, a Roman client state. Upon arrival, Caesar discovered that Pompey had been assassinated on the orders of Ptolemy XIII. Caesar attempted to reconcile the siblings, but a discontent Ptolemy XIII and his adviser Potheinos raised forces against Caesar and Cleopatra. Reinforcements lifted the siege in early 47 BC, and Ptolemy XIII died shortly afterwards in the Battle of the Nile. Arsinoe IV (Cleopatra's younger sister and a rival claimant to the throne) was exiled, and Caesar, now dictator, declared Cleopatra and her younger brother Ptolemy XIV co-rulers of Egypt. However, Caesar maintained a private affair with Cleopatra that produced a son, Caesarion, before he departed Alexandria for Rome.
