Yes. This is actually quite demonstrable. Zionism as a philosophy did not even begin until the 1880s and Altneuland (Herzl's foundational book) was not published until 1902. However, we have a long history of Anti-Semitism throughout the world for millenia before this.
Israelites and, later, Judeans, were hated by other nations, but this type of hatred was no different than other ethno-nationalist hatreds between states and would bear no resemblance to Anti-Semitism today. Anti-Semitism as a distinct phenomenon probably dates from the time of the Seleucid Greek Empire in 200s B.C.E., when the more religious Jews refused to accede to Hellenic culture and were branded as odd or traitorous. However, it solidified during the diaspora. The Jews lost a revolt against their Roman overlords around 70 C.E., and as punishment the Romans forced all the Jews to leave Israel. They were scattered to every point of the compass, all over Africa and Europe. Wherever they wound up, the Jews sought to preserve their separate ethnic and religious identity. This set them apart, made them different.
While Christianity and Islam are not inherently Anti-Semitism, their doctrines are easily to meld to an Anti-Semitic world vision and historically have been melded in such ways from the inception of these religions in the 1st and 7th centuries C.E. respectively. Christianity's main thrust of Anti-Semitism comes from the crucifixion of Jesus, i.e. deicide. Christians also focused on the passages of the Old Testament which argue that Jews were in contravention to Divine Edicts and passages in the New Testament where Jesus condemns the actions of the Pharisees. Islam has several Anti-Semitic thrusts. In addition to the Christ-killing (which is not deicide in Islam since Jesus is not God in Islamic theology and because Jesus eluded the attempt to crucify him), Muslims have made the argument that Jews are the killers of the Prophets plural, even though Jesus was the only one of the 35 prophets in the Qur'an who Jews attempted to kill (per Islamic teachings). Additionally, Muhammad and the early Muslims had negative political and military relationships with Arabian Jews which led to Anti-Semitism having a greater prominence in the early Islamic tradition.
All of these things occurred long before Zionism.
Hatred of Jews has existed continuously for as long as Jews have.

This should be self-evident. The Logic goes thus: Anti-Semites oppose any Jewish aspiration to freedom and/or power. Zionism promotes Self-Determination for the Jewish people which is an aspiration to freedom and power. Therefore, Anti-Semites oppose Zionism. Additionally, many people who are Anti-Semitic see Jews as running some sort of international cabal to strip power from everyone else. Equipped with a country, who knows what further havoc Jews could cause.
That depends on whether it's religious or secular Zionism. Religious Zionism is found in the Tanach (Jewish Bible). Theodor Herzl is considered the father of modern political Zionism.
The usual disintinction is between (traditional) religious antisemitism and racial antisemitism. The latter arose after religious toleration was accepted in most European countries and religious antisemitism lost much of its force. Racial antisemitism arose from about 1870 onwards and operates with conspiracy theories.
Zionism originated in Austria with Theodor Herzl.
Theodore Herzl is considered the father of Zionism.
The word is anti-Semitism, or better antisemitism(as there is no such thing as 'semitism' that Jew baiters are 'anti').
antisemitism is the longest hatred cause in history that still survives today. Among the most common manifestations of antisemitism throughout history were pogroms. The first such incident to be labeled a pogrom is believed to be anti-Jewish rioting in Odessa in 1821. That was in Russia. But this has been practice during millennial.
Anti-Zionism is a movement which denies the right of Israel to exist, and the right of the Jewish people to the Land of Israel. However, Israel has been the Jewish homeland since biblical times. Although much of Anti-Zionism is devoted particularly to the State of Israel, Anti-Zionists reject the idea of any Jewish State anywhere in the world as an unnatural, undesirable, and wrong situation.
