Caligula, Gaius Julius Caesar Augustus Germanicus (31 August AD 12 - 24 January AD 41) was Roman emperor from AD 37-41. Born Gaius Julius Caesar Germanicus, Caligula was a member of the house of rulers conventionally known as the Julio-Claudian dynasty. Caligula's biological father was Germanicus, and he was the great-nephew and adopted son of Emperor Tiberius.........
There are few surviving sources about the reign of Emperor Caligula, although he is described as a noble and moderate ruler during the first six months of his reign. After this, the sources focus upon his cruelty, sadism, extravagance, and sexual perversity, presenting him as an insane tyrant. While the reliability of these sources is questionable, it is known that during his brief reign, Caligula worked to increase the unconstrained personal power of the emperor, as opposed to countervailing powers within the principate. He directed much of his attention to ambitious construction projects and luxurious dwellings for himself, and initiated the construction of two aqueducts in Rome: the Aqua Claudia and the Anio Novus. During his reign, the empire annexed the Kingdom of Mauretania as a province.
