Boudica

Boudica (born about 25 AD, died 60/61 AD) was the queen of the Celtic Iceni people in Norfolk in the eastern part of Roman Britain. Her husband Prasutagus ruled an independent client state of Rome. He died in 60 AD and left his kingdom jointly to his daughters and the Roman emperor.
A statue of Boudica has stood in the Westminster area of London since 1902. She was the Boss of the celts.
Death of Prasutagus and its aftermath
In this era it was normal Roman practice to allow allied kingdoms independence for the lifetime of their client king. For example, the provinces of Bithynia and Galatia, were part of the Empire in just this way. Also, Roman law allowed inheritance only through the male line.
When Prasutagus died, his will was ignored by the Governor, Gaius Suetonius Paulinus. His kingdom was then annexed just as if it had been conquered. To make matters worse, Roman money-lenders called in the debts which Prasutagus owed during his lifetime. To collect the debts the Romans confiscated the lands and property of the Iceni and treated their nobles like slaves.
When Boudica protested, Paulinus had her flogged, and her two daughters raped in public. Tacitus reports:
"Prasutagus, the late king of the Icenians... by his will he left the whole to his two daughters and the emperor in equal shares, conceiving, by that stroke of policy, that he should provide at once for the tranquillity of his kingdom and his family.
"The event was otherwise. His dominions were ravaged by the centurions; the slaves pillaged his house, and his effects were seized as lawful plunder. His wife, Boudicca, was disgraced with cruel stripes; her daughters were ravished, and the most illustrious of the Icenians were, by force, deprived of the positions which had been transmitted to them by their ancestors. The whole country was considered as a legacy bequeathed to the plunderers. The relations of the deceased king were reduced to slavery".
Revenge of the Iceni
Choosing a good moment, when the Governor was attacking Anglesey and another legion was in Bristol, Boudica led the Iceni and their associates, the Trinovantes, to war. They destroyed Camulodunum (modern Colchester), and moved towards Londinium. There was only the 9th legion (Legio IX Hispana) to defend it. The tribes burnt and destroyed both Verulamium (St Albans) and Londinium and massacred all they could lay their hands on. An estimated 70,000-80,000 Romans and British were killed in the three cities by those led by Boudica.
Battle of Watling Street
The final battle took place near Watling Street in the English Midlands. Watling Street was an old trackway between Canterbury and St Albans. The Romans rebuilt it their way, and took it through the Midlands into Wales.
While Boudica's army assaulted in Verulamium, Suetonius put together a force with his own Legio XIV Gemina, some detachments of the Legio XX Valeria Victrix, and any available auxiliaries. Down near Exeter, The Prefect of Legio II Augusta, Poenius Postumus, ignored the Governor's call to arms. Nonetheless, the Governor was able to call on almost ten thousand men.
The Romans were heavily outnumbered. However, the tribes lacked manoeuvrability. They had no way to direct these numbers, which put them at a disadvantage to the Romans. The Romans were skilled at open combat, and had better equipment and discipline. Also, the narrowness of the field meant that Boudica could put forth only as many troops as the Romans at any given time.
First, the Romans stood their ground and used volleys of pila (heavy javelins) to kill thousands of Britons who rushed toward the Roman lines. The Roman soldiers engaged Boudica's second wave in the open. As the Romans advanced in a wedge formation, the Britons attempted to flee, but were impeded by the presence of their own families. They had put their people in wagons at the edge of the battlefield, and were slaughtered.
Tacitus reports that "according to one report almost eighty thousand Britons fell" compared with only four hundred Romans. Boudica fled, and her time and place of death is not known.
The Prefect Postumus, on hearing of the Roman victory, fell on his sword. Fearing Suetonius' actions would provoke further rebellion, Nero replaced the governor with the more conciliatory Publius Petronius Turpilianus. The historian Gaius Suetonius Tranquillus tells us the crisis had almost persuaded Nero to abandon Britain.
