Alea iacta est (also seen as alea jacta est) is Latin for "The die is cast". Actually quoted by Suetonius as iacta alea est [ˈjakta ˈaːlɛa ɛst], it is what Julius Caesar is reported to have said on January 10, 49 BC as he led his army across the River Rubicon in northern Italy. With this step, he entered Italy at the head of his army in defiance of the Roman Senate and began his long civil war against Pompey and the Optimates.
The phrase is still used today to mean that events have passed a point of no return, that something inevitable will happen, i.e., he cannot take back what he has done, much like the gambler who has already thrown the dice. Caesar was said to have borrowed the phrase from Menander, his favorite Greek writer of comedy. Plutarch reports that these words were said in Greek:
He [Caesar] declared in Greek with loud voice to those who were present 'Let the dice be cast' and led the army across.
– Plutarch, 'Life of Pompey, 60.2.9'

In another context, "iacta est" could be translated as "was cast", i.e., as a "simple past." It is generally assumed, e.g. by Shakespeare, that Caesar here meant "The die has been cast" i.e., "The die is now cast" and not "The die was cast."
According to Lewis and Short1, the phrase used was a future active imperative, Jacta alea esto, "Let the die be cast!", or "Let the game be ventured!" This is the meaning of Plutarch's third-person imperative ἀνεῤῥίφθω κύβος.
By the first century AD 'alea' refers to the early form of backgammon that was played at Caesars time. Augustus (Octavian) mentions winning this game in a letter. Dice were commonly known in Roman times and generally known as 'cubus'. It has thus been suggested that another probable translation of the phrase would be 'the backgammon game has begun'.
