Zionism is an international movement, originally for the establishment of a Jewish homeland in Palestine, and later for the support of modern Israel. A Zionist is an advocate or supporter of Zionism.
In the 1930s, there were several small Zionist youth movements in Hungary. These grew when Hungary reoccupied the territories it had lost after World War I. They grew further after each wave of anti-semitic laws, and when Jewish refugees arrived after 1942.
These youth movements played an important role in the Hungarian resistance, creating false identification papers, getting news out about what was happening in nazi-occupied countries, rescuing Jews, smuggling refugees across the border to Romania, and setting up homes to protect thousands of Jewish children and adults.
