Germanicus
Germanicus (Latin: "Germanicus Julius Caesar"; 24 May 15 BC – 10 October AD 19) was a member of the Julio-Claudian dynasty and a prominent general of the Roman Empire, who was known for his campaigns in Germania.
The son of Nero Claudius Drusus and Antonia Minor, Germanicus was born into an influential branch of the patrician "gens Claudia".
The agnomen "Germanicus" was added to his full name in 9 BC when it was posthumously awarded to his father in honor of his victories in Germania.
In AD 4, he was adopted by his paternal uncle, Tiberius, who succeeded Augustus as Roman emperor a decade later.
As a result, Germanicus became an official member of the "gens Julia", another prominent family which he was related to on his mother's side.
His connection to the Julii was further consolidated through a marriage between himself and Agrippina the Elder, a granddaughter of Augustus.
He was also the nephew of Tiberius, the older brother of Claudius, the father of Caligula, and the maternal grandfather of Nero.
During the reign of Augustus, Germanicus enjoyed an accelerated political career as the heir of the emperor's heir, entering the office of quaestor five years before the legal age in AD 7.
He held that office until AD 11, and was elected consul for the first time in AD 12.
The year after, he was made proconsul of Germania Inferior, Germania Superior, and all of Gaul.
From there he commanded eight legions, about one-third of the entire Roman army, which he led against the Germanic tribes in his campaigns from AD 14 to 16.
He avenged the Roman Empire's defeat in the Teutoburg Forest and retrieved two of the three legionary eagles that had been lost during the battle.
In AD 17 he returned to Rome where he received a triumph before leaving to reorganize the provinces of Asia Minor, whereby he incorporated the provinces of Cappadocia and Commagene in AD 18.
While in the eastern provinces, he came into conflict with the governor of Syria, Gnaeus Calpurnius Piso.
During their feud, Germanicus became ill in Antioch, where he died on 10 October AD 19.
His death has been attributed to poison by ancient sources, but that was never proven.
As a famous general, he was widely popular and regarded as the ideal Roman long after his death.
To the Roman people, Germanicus was the Roman equivalent of Alexander the Great due to the nature of his death at a young age, his virtuous character, his dashing physique, and his military renown.

Kaya Alp was, according to Ottoman tradition, the son of Kızıl Buğa and the father of Suleyman Shah, who was, in turn, the grandfather of Ertuğrul, and the great grandfather of the Ottoman Empire founder, Osman I.
Drusus Caesar
Drusus Caesar (AD 8 – AD 33) was the adopted grandson and heir of the Roman Emperor Tiberius, alongside his brother Nero.
Born into the prominent Julio Claudian dynasty, Drusus was the son of Tiberius' general and heir, Germanicus.
After the deaths of his father and of Tiberius' son, Drusus the Younger, Drusus and his brother Nero Julius Caesar were adopted together by Tiberius in September AD 23.
As a result of being heirs of the emperor, he and his brother enjoyed accelerated political careers.
Sejanus, the prefect of the Praetorian Guard, had become powerful in Rome and is believed by ancient writers such as Suetonius and Tacitus to have been responsible for the downfall of Drusus the younger.
As Sejanus' power grew, other members of the imperial family began to fall as well.
In AD 29, Tiberius wrote a letter to the Senate attacking Nero and his mother, and the Senate had them both exiled.
Two years later, Nero died in exile on the island of Ponza.
Drusus was later imprisoned following similar charges as his brother, and remained in prison from AD 30 until his death three years later.
Their deaths allowed for the adoption and ascension of their third brother, Gaius Caligula, following the death of Tiberius in AD 37.
