Bar KochbaJewish outrage at his actions led to one of the single greatest revolts of the Roman Era. Simon Bar Kosiba led the uprising, which began in full force in 132 CE.
For many years, historians did not write very much about Simon Bar Kosiba. But then, archeologists discovered some of his letters in Nahal Hever near the Dead Sea. If you go to the Israel Museum you can see these letters and they are absolutely fascinating. Some of them pertain to religious observance, because his army was a totally religious army. But they also contain a tremendous amount of historical facts. We learn that the Jews participating in the revolt were hiding out in caves. (These caves have also been found ― full of belongings of Bar Kosiba's people. The belongings ― pottery, shoes, etc. ― are on display in the Israel Museum, and the caves, though bare, are open to tourists.)
From the letters and other historical data, we learn that in 132 CE, Bar Kosiba organized a large guerilla army and succeeded in actually throwing the Romans out of Jerusalem and Israel and establishing, albeit for a very brief period, an independent Jewish state. The Talmud (Sanhedrin 97b) states that he established an independent kingdom that lasted for two and half years.
Bar Kosiba's success caused many to believe ― among them Rabbi Akiva, one of the wisest and holiest of Israel's rabbis ― that he could be the Messiah. He was nicknamed "Bar Kochba" or "Son of Star," an allusion to a verse in the Book of Numbers (24:17): "there shall come a star out of Jacob." This star is understood to refer to the Messiah.
Bar Kochba did not turn out to be the Messiah, and later the rabbis wrote that his real name was Bar Kosiva meaning "Son of a Lie" ― highlighting the fact that he was a false Messiah.
At the time, however, Bar Kochba ― who was a man of tremendous leadership abilities ― managed to unite the entire Jewish people around him. Jewish accounts describe him as a man of tremendous physical strength, who could uproot a tree while riding on a horse. This is probably an exaggeration, but he was a very special leader and undoubtedly had messianic potential, which is what Rabbi Akiva recognized in him.
Jewish sources list Bar Kochba's army at 100,000 men, but even if that is an overestimate and he had half that number, it was still a huge force.
United, the Jews were a force to be reckoned with. They overran the Romans, threw them out of the land of Israel, declared independence and even minted coins. That is a pretty unique event in the history of the Roman Empire.

Why Did the Jews Lose?Apparently the Jews came very close to winning the war. Indeed, they did win for a time. Why did they lose in the end? The sages say they lost because they were too arrogant. Having tasted victory they adopted the attitude of , "by my strength and my valor I did this." (Deut. 8:17)
Bar Kochba too became arrogant. He saw himself winning. He heard people calling him the Messiah. Certainly, if Rabbi Akiva thought so, then he had the potential to be Israel's Ultimate Leader. He also became corrupted by his power and even beat his uncle, the great Rabbi Elazar HaModai, to death, having accepted false accusations that he was a Roman spy (3). Because of these faults he began to lose battles and was forced into retreat and guerrilla warfare.
In Judaism we are taught that while people must make the effort, it is God that wins the wars. It is not human strength nor human might that's doing it.
The Fall of BetarBar Kochba made his final stand in the city of Betar, which is to the southwest of Jerusalem. You can go visit it today, thought ancient Betar has not been excavated. The Talmud (in Gittin 57a) relates what happened in Betar:
They had the custom in Betar that when a baby boy was born they planted a cedar tree and for a baby girl they planted a pine tree, and when they would marry they would cut them down and make a marriage canopy of the branches. One day the daughter of Caesar was passing and the shaft of her litter broke. They cut down a cedar and brought it to her. The Jews of Betar fell upon them and beat them. They reported to Caesar that the Jews were rebelling and marched against them... they killed [Jewish] men, women and children until their blood flowed into the Mediterranean Sea... It was taught that for seven years the gentiles cultivated their vineyards with the blood of Israel without requiring manure for fertilization.The city fell on the saddest day in the Jewish calendar ― the 9th of Av of the year 135, the same date as both the First and the Second Temple fell.
The Romans, in their fury, did not want to allow the Jewish bodies to be buried; they wanted to leave them out in the open to rot. According to tradition, the bodies lay in the open for months but did not rot. Today, when Jews say the Grace after Meals, Birkat HaMazon, they add a special blessing (ha tov u'mativ) as a way of thanking God for this act of mercy in Betar.
Exhausted, the Romans have had enough of the Jews who had caused them more manpower and material losses than any other people in the history of Empire. At the end of the Bar Kochba revolt, Hadrian decided that the way not to have another one is to cut off the Jews from connection to their beloved land.
