Anti-Semitism goes at least as far back as the day Jesus Christ was sentenced to crucifixion. Followers of Christ blamed the Jewish for the death of their messiah, and so despised them. The Romans kicked the Jews out of Rome for failing to worship the Roman gods, and, when Rome converted to Christianity in the early fourth century, the Jews were certainly not welcome to back; they had even been given the name "Christ killers". The theological basis of anti-Semitism is found in the New Testament of the Holy Bible, which states in Matthew 27:.
"And the governor [Pilate] said, 'Why, what evil hath he [Christ] done?' But they [the Jews] cried out the more, saying, 'Let him be crucified.' .
When Pilate saw that he could prevail nothing, but that rather a tumult was made, he took water, and washed his hands before the multitude, saying, 'I am innocent of the blood of this just person: see ye to it.' .
Then answered all the people, and said, 'His blood be on us, and on our children.'".
It was not until 1965 that the Vatican established that the Jewish people were not to be held responsible for the death of Christ. The bias against Jews, which started out strictly on a religious level, grew to the point where Jews became scapegoats for any ill that happened to befall the city, village, or country they lived in. They were denied citizenship in Christian countries because they would not give up their religion, and were forced to live in ghettos, separate from Christian communities. Jews were blamed for everything, even being accused of poisoning wells and starting the bubonic plague in 1348. Ignoring the fact that the plague also killed thousands of Jews, enraged and hate-filled mobs slaughtered thousands of Jews in a massacre that would be topped only much later in history by Adolf Hitler#, who would end up being known as the archetype of vicious anti-Semitism.
Hitler was born in a small town in Austria called Braunau Am Inn.
