A western Berber kingdom born of a betrayed peace offer and a king's betrayal of his own son-in-law, surviving two centuries as Rome's client and reaching its height under a scholar-king married to Cleopatra's own daughter, before an emperor executed its last king for wearing too fine a robe.

Bocchus's rejected peace embassyTreaty
Bocchus sent envoys to Rome asking for a treaty of friendship at the very outset of the Jugurthine War - an alliance that would have served Rome's own interest in the war then just beginning, left to die by senators too distracted by Numidian bribes to answer a king who had nothing yet to offer them.

Bocchus allies with JugurthaTreaty
Persuaded by his own son-in-law's warning that Rome's appetite for conquest would reach Mauretania eventually regardless of what Bocchus did, the king took up arms alongside Jugurtha against Rome, marching with him toward the Roman spoils gathered at Cirta.

Bocchus betrays Jugurtha to SullaTreaty
Judging Jugurtha's cause lost and unwilling to let a losing war cost him his own throne, Bocchus turned an ambush Jugurtha had proposed against the Roman quaestor Sulla back on its own author, delivering his son-in-law to Rome in chains.

A divided kingdom backs CaesarTreaty
By the time Rome's own civil war reached Africa, two kings named Bocchus and Bogud held Mauretania between them, and both backed Julius Caesar against the Pompeian refuge in neighboring Numidia - the same calculation of self-interest that had once cost Jugurtha his throne, now running in Rome's favor a second time.

Juba II transferred to MauretaniaTreaty
Trading Juba's own hereditary Numidian throne - by then largely absorbed into Roman territory - for Mauretania and the former possessions of Bocchus and Bogud, Augustus reunited the kingdom under a single client king for the first time since Caesar's civil war, and installed as its ruler a man raised in Italy and married to Cleopatra Selene, daughter of Antony and Cleopatra.

The Gaetulians rise against JubaRevolt
Discontented with Juba's own rule and unwilling to be governed by Romans at one remove, the Gaetulians rose, ravaged neighbouring territory and killed a number of the Roman soldiers sent against them before Cornelius Cossus subdued them - a revolt substantial enough that Cossus was voted triumphal honours and the title Gaetulicus for ending it.

A treaty Rome's greed refused
formationDrafted from Pollard), The Catiline and Jugurtha of Sallust, Translated into English (1882)
Bocchus ruled all the Mauritanians, the westernmost of Africa's
peoples, a king who knew the Roman name and nothing more of Rome
itself until Jugurtha's own war brought the two into contact. At the
very outset of that war, Bocchus had sent an embassy to Rome asking
for a treaty of friendship - an alliance that would have served Rome's
own interest in the war then just beginning. It came to nothing. The
same senators whose greed had already sold Jugurtha half a kingdom and
a king's own silence let the offer die rather than trouble themselves
over a distant ruler with nothing yet to offer them.

A marriage that meant less than it looked
Bocchus had also, some time before, married one of Jugurtha's own
daughters - a tie the text notes was held cheaply among both
Numidians and Mauritanians, where kings kept as many wives as they
could afford and no single marriage carried the weight it might
elsewhere. It was a slight bond, but it was there when Jugurtha, cast
off by Rome's rejected friendship and needing every ally he could
still find, came to Bocchus with an offer of his own.
A speech about a hunger that never stops
The two kings met with their armies at an agreed place, exchanged
pledges, and Jugurtha made his case in a single speech: the Romans
were unjust and boundlessly greedy, the common enemy of every people,
and had no more real quarrel with Bocchus than they had once had with
Carthage, or with King Perses of Macedon after that - each simply the
richest victim within reach at the time. Whoever they had not yet
attacked would be attacked eventually; it was only a matter of whose
turn came next. Persuaded, Bocchus took up arms against Rome
alongside his new son-in-law, marching with him toward the Roman
spoils gathered at Cirta.
A king who played both sides
peakDrafted from Pollard), The Catiline and Jugurtha of Sallust, Translated into English (1882)
Alliance with Jugurtha did not stop Bocchus from testing the other
side. As the Roman general Metellus pressed the war, he sent envoys
urging Bocchus to abandon a doomed son-in-law before his own kingdom
shared Jugurtha's ruin - warning him that a war easy to begin was hard
to end, and that only the victor, not the man who started it, got to
choose when it stopped. Bocchus answered warmly, professing he wanted
peace but pitied Jugurtha's misfortune, and would treat if Jugurtha
were offered the same terms. Messages went back and forth for months
without a decision either way.
A third of a kingdom, offered twice
When the Roman consul Marius pushed Jugurtha out of Capsa and a string
of other strongholds, Jugurtha sent for Bocchus again, this time with
a concrete bribe attached: a third of Numidia itself, once the war was
won or settled on terms that left Bocchus's own lands untouched.
Bribery had worked on Bocchus's own courtiers before it worked on the
king, but it worked. Bocchus led his army into Numidia and joined
Jugurtha in a night attack on Marius's own column, catching the Romans
before they could form ranks or receive orders - a chaotic, close-run
fight that felt, by the Roman survivors' own account, more like a
brawl with bandits than a battle between armies.
A ruin he chose not to share
The fighting that followed wore Bocchus down rather than Marius.
Months of further reverses convinced him that Jugurtha's cause, and
not Rome's, was the one about to fail - and when Jugurtha himself
proposed one final scheme, a peace conference at which Bocchus would
seize the Roman quaestor Sulla and hand him over as a hostage, Bocchus
turned the plan back on the man who had suggested it. An ambush laid
for Sulla caught Jugurtha instead, and Bocchus delivered his own
son-in-law to Rome in chains rather than let a losing war cost him his
own throne.

A kingdom split in two
contractionDrafted from Way), Caesar: Alexandrian, African and Spanish Wars (1955)
By the time Rome's own civil war reached Africa, six decades after
Bocchus handed Jugurtha to Sulla in chains, the single Mauretanian
throne he had ruled no longer existed. Two kings, both named in the
record only as Bocchus and Bogud, now held the country between them -
and both, unlike their Numidian neighbor Juba I, backed Julius Caesar
rather than the Pompeians who had made Africa their own refuge after
Pharsalus.

The safer bet, twice over
The choice made sense on its own terms. Juba's Numidia could field
four legions and cavalry beyond counting, resources the two smaller
Mauretanian kingdoms could not match alone - but Caesar's own cause in
Africa was reinforced by Sittius, a Roman adventurer who had spent
years already operating in the region with a private army of his own,
giving Bocchus and Bogud a patron whose interests ran alongside
theirs rather than a neighbor whose ambitions, like Jugurtha's before
him, might eventually reach for their own thrones next. Where a
Mauretanian king had once married into Numidia's royal house and
fought Rome at its side, his successors now stood against Numidia
and beside Rome instead - the same calculation of self-interest,
running in the opposite direction.
Two names outlasting one kingdom's memory
Whether Bocchus and Bogud divided a kingdom once ruled by a single
line, or represented two houses with older claims of their own, goes
unexplained in the war's own narrative. What that narrative shows
plainly is a Mauretania no longer capable of acting as one power even
when its interests aligned - two kings making the same choice
separately, rather than one making it for both.
A kingdom of his fathers
contractionDrafted from Foster), Dio's Roman History, Volume VI: Books 51-55 (1955)
Not long after Actium, Augustus settled the fate of a boy who had
been paraded through Rome as a child in his father's triumph and then
raised at the emperor's own court. Juba, son of the Numidian king
Juba I, was given both a bride and a throne: Cleopatra Selene,
daughter of Antony and Cleopatra, and "the kingdom of his fathers" -
Numidia, the realm his father had lost to Caesar's own conquest a
generation before. It was restoration by favour rather than by right,
granted to a man who had spent his whole life among the people who
had destroyed his father's kingdom in the first place.

The arrangement did not last as first made. In 25 BC Augustus moved
Juba again, trading his hereditary Numidian throne - by then already
folded largely into Roman provincial territory - for Mauretania and
the former domains of Bocchus and Bogud. For the first time since
Caesar's civil war split the kingdom between two rival kings,
Mauretania answered to one ruler alone, and that ruler owed the whole
of his throne, twice over now, to Roman favour rather than Mauretanian
succession.
A revolt Rome had to finish for him
Favour did not buy loyalty from the kingdom's own subjects. Around AD
6 the Gaetulians, a people within Juba's own territory, rose against
him, unwilling to accept rule at one remove by a king who was himself
little more than a Roman appointee. They ravaged the country
bordering their own lands and killed a number of the Roman soldiers
sent to help put them down, gaining enough ground that it took a
dedicated Roman commander, Cornelius Cossus, to finish the campaign -
a service substantial enough that Cossus returned to Rome with
triumphal honours and a new title, Gaetulicus, taken from the very
people he had subdued in another king's name.
Died lately
contractionDrafted from Falconer), The Geography of Strabo (1856)
A geographer writing in the last years of his own life, revising an
account of the western world he had been building for decades, paused
over Mauretania long enough to note what had become of the king who
ruled it. Juba, he records, had held the kingdom "having received it
from Augustus Caesar, in addition to his paternal dominions" - the
same double grant of Numidia and then Mauretania that had defined the
whole of his reign. And then, in the same breath, the geographer
closes the account of him: Juba "died lately, and was succeeded by
his son Ptolemy, whose mother was the daughter of Antony and
Cleopatra."

Nothing in the geographer's own words marks the succession as
contested, delayed, or violent. Ptolemy took his father's throne as
plainly as the sentence that records it - the son of Cleopatra Selene
inheriting a kingdom his grandmother had lost and his father had spent
a lifetime being given back, piece by piece, at another empire's
discretion.

A purple robe was the last straw
endDrafted from Forester), The Lives of the Twelve Caesars: Caligula (1855)
Three generations after Bocchus and Bogud backed Caesar's winning
side, the Mauretanian throne belonged to Ptolemy, grandson of Mark
Antony through his mother, Cleopatra Selene, and son of Juba, a king
whom the emperor Caligula counted among his own cousins and invited to
Rome with every mark of honor. The reception did not last. Caligula
had the young king put to death for no greater offense, by the
historian Suetonius's own account, than that Ptolemy had drawn every
eye in the theatre at a public exhibition by the splendor of his own
purple robe - a display of royal magnificence the emperor could not
forgive in a client king who was supposed to owe his own position to
Rome's favor.

A death with an empire attached
Ptolemy's execution, probably in AD 40, left Mauretania without an
heir Rome recognized, and the emperor who had ordered the killing
simply absorbed the kingdom rather than name a successor. The
Mauretanian throne Bocchus had first brought into the Roman historical
record a century and a half earlier, through an embassy Rome's own
corrupt senators had once refused to answer, ended the same way most
of the ancient world's smaller kingdoms eventually did: annexed by an
emperor who wanted the throne more than he wanted any reason to
justify taking it.
