Question: Who is blamed by Tacitus for provoking a queen of the Celtic Iceni tribe?

Context paragraphs:
Boadicea (disambiguation): Boadicea was the queen of the British Iceni tribe who led an uprising against the forces of the Roman Empire.  The name may also refer to:

Iceni Way: The Iceni Way is a collective name for several long distance footpaths running from Knettishall Heath to Hunstanton via the Little Ouse and Great Ouse valleys in the English county of Norfolk.  The name comes from the Iceni tribe that once lived in the area.

Dulgubnii: The Dulgubnii are a Germanic tribe mentioned in Tacitus' "Germania" (Chapter ) as living in what is today northwest Germany.  Tacitus describes them being to the north of the Angrivarii and Chamavi, and as having moved from the north into the area once belonging to the Bructeri, between Ems, Lippe, and Weser.  In this same area as the Dulgubnii, north of the Chamavi and Angrivarii, were the Chasuarii, and north of these, on the North Sea coast, where the Chauci.  The Chasuarii's name is thought to derive from the River Hase which feeds into the middle of the Ems from the east, just northwest of the area associated with the Angrivarii, on the Weser.  So from Tacitus it appears that the Dulgubnii probably lived near the Weser.

Catus Decianus: Catus Decianus was the procurator of Roman Britain in AD 60 or 61.  Tacitus blames his "rapacity" in part for provoking the rebellion of Boudica.  Cassius Dio says he confiscated sums of money which had been given by the emperor Claudius to leading Britons, declaring them to be loans to be repaid with interest.

Boadicea and Her Daughters: Boadicea and Her Daughters is a bronze sculptural group in London featuring Boudica, queen of the Celtic Iceni tribe who led an uprising in Roman Britain.  It is located to the north side of the western end of Westminster Bridge, near Portcullis House and Westminster Pier, facing Big Ben and the Palace of Westminster across the road.  It is considered the "magnum opus" of its sculptor, the English artist and engineer Thomas Thornycroft.  Thornycroft worked on it from 1856 until shortly before his death in 1885, sometimes assisted by his son William Hamo Thornycroft, but it was not erected in its current position until 1902.

Nemetes: The Nemetes (Ancient Greek: Νεμῆται ; German: "Nemeter" ), by modern authors sometimes called Nemeti, were an ancient Celtic tribe living by the Rhine where Ariovistus had led them, the Suebi and other allied Germanic peoples in the second quarter of the 1st century BC.  The Roman name for Speyer, "Noviomagus Nemetum", reflects this city's status as the Nemetes' tribal capital.  According to Tacitus, they were "unquestionably Germanic".  The name of the tribe, however, is Celtic as the name of its main town "Noviomagus" meaning "noviios" 'new' and "magos" 'plain', 'market' (cf. Old Irish "mag" 'plain'), as are those of a number of gods worshipped in their territory, including Nemetona, who is thought to have been their eponymous deity.  Both of these names derive from the Celtic root "nemeto-", referring to sacred spaces.

Boudica (film): Boudica (released in the United States as Warrior Queen) is a British television film released in 2003.  Starring Alex Kingston, Steven Waddington and Emily Blunt, in her film debut, the film is a biopic of the queen of the Iceni tribe, Boudica.

Boudica: Boudica or Boudicca ( , Latinised as Boadicea or Boudicea , and known in Welsh as Buddug ] ) was a queen of the British Celtic Iceni tribe who led an uprising against the occupying forces of the Roman Empire in AD 60 or 61, and died shortly after its failure.  She is sometimes considered a British folk hero.

Battle of Camulodunum: The Battle of Camulodunum, also known as the Massacre of the Ninth Legion, (60 or 61 AD) was the major military victory of the Iceni and their allies over an organised Roman army during the revolt of Boudica against the Roman occupation of Britain.  A large vexillation of the "Legio IX Hispana" were destroyed by the rebels.  Attempting to relieve the besieged "colonia" of Camulodunum (Colchester, Essex), legionaries of the Legio IX Hispana led by Quintus Petillius Cerialis, were attacked by a horde of British tribes, led by the Iceni.  Possibly 80% of the Roman foot-soldiers were killed in the battle.  The event is recorded by the historian Tacitus in his "Annals".

Buri tribe: The Buri were a Germanic tribe mentioned in the Germania of Tacitus, where they initially "close the back" of the Marcomanni and Quadi of Bohemia and Moravia.  It is said that their speech and customs were like those of the Suebi.  Such a statement implies that the Buri had recently come from the direction of the Baltic Sea, as other Germanic settlers in Bohemia and Moravia were newcomers, having driven out the Celtic Boii and taken their lands.  In Tacitus, the Buri are not linked to the Lugii.
