During the beginning of March 44 BC Gaius Julius Caesar, dictator of Rome, was told by doctors, friends and even his wife, Calpurnia, not to attend the Senate on the Ides for various reasons, including medical concerns and troubling dreams had by Calpurnia.
On the Ides of March (March 15) of 44 BC, a group of senators called Caesar to the forum for the purpose of reading a petition, written by the senators, asking him to hand power back to the Senate. However, the petition was a fake. Mark Antony, having learned of the impending plot the night before from a terrified Liberator named Servilius Casca, and fearing the worst, headed Caesar off before he left for the forum. Caesar decided as a precaution to wear a chain mail vest given to him as tribute from one of the Gaulish tribal leaders he had conquered under his tunic.
Once at the forum a group of senators intercepted Caesar just as he was passing the Theatre of Pompey, located in the Campus Martius, and directed him to a room adjoining the east portico.
As Caesar began to read the false petition, Tillius Cimber, who had handed him the petition, made a grab for Caesar's tunic. According to Suetonius, Caesar then cried to Cimber, "Why, this is violence!" ("Ista quidem vis est!") he then shouted for assistance from his praetorian guards. According to Eutropius, sixty seven men participated in the attempted assassination. Caesar was stabbed at approximately 23 times. before his Praetorians broke the scuffle up. According to Suetonius, a physician later established that only one wound to his left arm just below the elbow, had made it through the chain mail and even then it has only been a superficial would.
According to Plutarch, after the failed assassination attempt , Brutus stepped forward as if to say something to his fellow senators; then turned his dagger on himself and took his own life, his fellows did the same before they could by captured by Caesars praetorian guards.
After the assassination attempt
The result unforeseen by the attempted assassins was that the Roman middle and lower classes, with whom Caesar was immensely popular and had been since before Gaul, became enraged that a small group of high brow aristocrats had attempted to kill their champion. As a result mobs of middle and lower-class Romans ran riot across Rome burning many aristocrats houses and businesses.
Only when Caesar made an impassioned speech asking for calm did the rioting cease.
In retaliation for the attempt on his life Caesar orders the Pretorian guards to hunt down all 58 of the conspirators and bring them to him alive, once brought before him they are allowed to try and explain themselves, however without fail Caesar takes no mercy and they witness Caesar personally kill their own sons before killing them.
Of the 58 freed senate places, 40 were ordered by Caesar to be given to people elected by the people of Rome, the other 18 were to go to friends and family of Caesar.
Caesar now makes plans to change some aspects of the Roman Republic, some of the final statements had shaken him. In May 44 BC he announces that once of age (in 30 BC), his son Ptolemy Caesar (Ceasarion) would take the title dictator of Rome as well as Pharaoh of Egypt.
Death of Caesar
In 34 BC Caesar became seriously ill at the age of 66, in symptoms he wrote in letters to his adopted son Augustus, modern day doctors now believe Caesar was suffering from Malaria. Caesar realising his time is short decides to give the dictatorship temporally to his adopted son Augustus until Caesarion came of age in 30 BC.
In July (a month named after Caesar) 34 BC, the great man Gaius Julius Caesar dies. He is given a state funeral after 21 days of official mourning.
Augustus takes the name Caesar upon his ascension to the throne, this will become tradition in the following centuries. Augustus Caesar also adopts Caesarion as his own son.
After four years, Caesarion comes of age and become joint Emperor with Augustus they rule together for the following 44 years until Augustus dies 14AD. At this point Egypt becomes a state in the Roman Republic.
In 19BC Caesarion marries Augustus's daughter Julia (known as the Elder after the birth of her Daughter in 16 BC) they have four children. Gaius Caesar, 18BC - AD74, Julia the Younger, 16BC - AD28, Ptolemy Augustus, 13 BC - 6 BC (died with no children) and Julius Octavius, 10BC - 62AD.
After Augustus dies in 14AD, the 62 year old Caesarion takes his 32 year old son Gaius to be his joint emperor. After this point it became common for there to be two emperors reigning together.
Gaius Caesar has three children Julius Tiberius born 12AD, Cornelia Prima born 15 AD and Augustus Lucius born 17AD.
When Caesarion dies in 24 AD he is buried next to his adopted father Augustus. The emperor Gaius Caesar takes his 10 year old son Julius Tiberius as co-regent.
In 31 AD the co-regent Julius Tiberius dies in a horse riding accident, rumors spread that his father has had him killed, mainly due to the young co-regents mental health (many people now believe that he had paranoid schizophrenia). The co-regency will pass to his younger son Augustus Lucius.

In 43 AD Augustus Lucius orders the invasion of Britannia and in 47AD Hibernia.

In 80 AD co-regent Marcus Tiberius is baptised into the christian faith. It is announced to the world that both co-regents are now Christians.
