The Second World Zionist Congress met in Basel, Switzerland on 28 August 1898. and was the second meeting of the Zionist Organisation. The World Zionist Congress brought together delegates from across the world to raise funds, lobby support and create the institutions that would one day form the modern day Jewish State known as Israel, which was established in 1948. The Congress met every year from 1897 to 1901. The main focus of the Second Congress, as set out by its chair, Theodor Herzl, was to engage with Jewish communities in the diaspora and encourage them to adopt Zionism.

The Zionist Congress was established in 1897 by Theodor Herzl as the supreme organ of the Zionist Organization (ZO) and its legislative authority. In 1960 the names were changed to World Zionist Congress and World Zionist Organization (WZO), respectively. The World Zionist Organization elects the officers and decides on the policies of the WZO and the Jewish Agency, including "determining the allocation of funds." The first Zionist Congress was held in Basel, Switzerland in 1897. Any Jew over age 18 who belongs to a Zionist association is eligible to vote, and the number of elected delegates to the Congress is 500. 38% of the delegates are allocated to Israel, 29% to the United States of America, and 33% to the remainder of the countries of the Diaspora. In addition there are about 100 delegates which are appointed by International Organizations affiliated with WZO.
