Political consulting is a form of consulting that consists primarily of advising and assisting political campaigns. Although the most important role of political consultants is arguably the development and production of mass media (largely television, direct mail, and digital advertising), consultants advise campaigns on many other activities, ranging from opposition research and voter polling, to field strategy and get out the vote efforts.
A druid was a member of the high-ranking priestly class in ancient Celtic cultures. The druids were religious leaders as well as legal authorities, adjudicators, lorekeepers, medical professionals and political advisors. Druids left no written accounts. While they were reported to have been literate, they are believed to have been prevented by doctrine from recording their knowledge in written form. Their beliefs and practices are attested in some detail by their contemporaries from other cultures, such as the Romans and the Greeks.
The earliest known references to the druids date to the 4th century BCE. The oldest detailed description comes from Julius Caesar's Commentarii de Bello Gallico (50s BCE). They were described by other Roman writers such as Cicero, Tacitus, and Pliny the Elder. Following the Roman invasion of Gaul, the druid orders were suppressed by the Roman government under the 1st-century CE emperors Tiberius and Claudius, and had disappeared from the written record by the 2nd century.
