Chmielnicki was one of the biggest anti-Semites in human history, on par with Hitler. His aim was genocide and his forces murdered an estimated 100,000 Jews in the most horrendous ways.
How did Jews come to be in Poland in the first place. They were invited there. King Boleslav of Poland invited the Jews, granting them unprecedented rights and privileges. This happened during a period of history known as "The Renaissance" which historians generally date from about 1350 to about 1650. Renaissance means "rebirth." Rebirth of what? Of knowledge. This is also a time when Jews made their way into Poland. Today we tend to think of Jewish life in Poland as being confined to the shtetl, but that did not happen until the 18th century. We also tend to think of Poland as synonymous with anti-Semitism, pogroms, etc. But during the time of the Renaissance the picture was quite different. Poland became Christian very late, only at the turn of the 11th century, and only then did it join the European community of nations (so to speak). After that, it took a couple of hundred years before Poland started to emerge as a nation-state with strong development potential. If you want to develop your country economically and culturally, who do you need? You need Jews.
Why were the Jews so necessary? First, they could read and write. J ews were always highly educated as they had to be literate to read and obey the Torah, and general education came along as part of the parcel. Second, Jews were excellent bankers, accountants, and administrators who knew how to keep the economy healthy.
So in 1264, King Boleslav of Poland granted a charter inviting the Jews there. The charter was an amazing document, granting Jews unprecedented rights and privileges.
Jews did not immediately flock into Poland, though some did settle there to test the waters. But when other countries started expelling -- Poland became an attractive destination point.
Then in 1569, Poland unified with Lithuania, and as a result expanded its borders to the east. What we know as the Ukraine today and some of Belorussia became vassal lands of Poland which was still a semi-feudal country. These lands needed to be managed and job openings in administration (at which Jews excelled) sprung up everywhere. Quite often Jews would lease tracks of land from the Polish nobility thus making them the middle men in the feudal economic structure of Eastern Europe.
In Poland, in the early 16th century, the Jews were allowed to have their own governing body called the Va'ad Arba Artzot-The Council of the Four Lands, which was composed of various rabbis from the four major Polish provinces (Great Poland, Little Poland, Volhynia and Polodia) who oversaw the affairs of the Jews in Eastern Europe. The Poles did not interfere with Jewish life and scholarship flourished.
Along with the growth in Torah scholarship there was growth in population. In 1500 there were about 50,000 Jews living in Poland. By 1650 there were 500,000 Jews. This means that by the mid 17th at least 30% or more of the Jewish population of the world was living in Poland!
Where did these Jews settle within Poland?
Jews of the Diaspora were generally urban people as they were historically not allowed to own land in most of the places they lived. However, they also created their own farm communities called shtetls (Yiddish for "small town). Although we tend to think of the shtetl today as a poor farming village (like in Fiddler on the Roof), during the Golden Age of Polish Jewry, many of these communities were actually quite prosperous. And there were thousands of them.
The Jews in these independent communities spoke their own language called Yiddish. Original Yiddish was written in Hebrew letters and was a mixture of Hebrew, Slavic, and German. (Note that Yiddish underwent constant development and "modern" Yiddish is not like the "old" Yiddish which first appeared in the 13th century, nor "middle" Yiddish of this period of time.)
Overall, the Jews did well, but working alongside Polish and Ukrainian Christians (who thought Jews killed Jesus) had its downside.
There were several instances of Christian rioting against Jews. For example, in 1399 in Poznan, a rabbi and 13 elders were accused of stealing Church property and they were tortured and burnt at the stake. (The Poles must have forgot the king's edict.)
Another problem was that Jews worked as administrators and tax collectors for Polish feudal lords. This did not make them popular among the local folk, who needed little encouragement to unleash their anti-Semitic rage.
This was especially true in places like the Ukraine, where the Catholic Poles were viewed as an occupying power in an Eastern Orthodox land, and the Jews -- being representatives of the occupation forces -- were the easiest to resent.
And while the Polish nobility might have needed the Jews, the common Poles didn't. There were instances when the Polish soldiers would purposely leave town, abandoning the Jews to the mercy (or lack thereof) of the Ukrainians. This happened, for example, in 1648 in the city of Tulchin. The Polish soldiers made a deal with the Cossacks and left town. The Jews defended the city by themselves until it fell and they were all slaughtered.
When the Ukrainians decided to throw the Poles out of their land, a full-scale massacres of Jews began.
The year 1635 saw the first big explosion of violence in Ukraine against Poles and Jews. But this attempt at the revolution was crushed. It returned with new vigor thirteen years later.
This second rebellion, in 1648, which succeeded in freeing a large part of the Ukraine from Polish rule, was led by a Ukrainian Cossack named Bogdan Chmielnicki. In large measure it was directed at the Jews.

And that one thing is this: The Jews need their own country -- Israel. And it certainly doesn't need to share that country with vicious, murderous Arabs. Of course, Kahane knew this as well as anyone.
