There was genuine concern for the welfare of Jews in Eastern Europe after the Kishinev pogrom.Initial negotiations
Initially, Herzl wasn't interested in the offer of a Jewish homeland in East Africa, as his focus was primarily on Palestine and its surrounding area. However, everything changed after the Kishnev Pogrom after which he redoubled his efforts to secure a Jewish homeland. Leopold Greenberg acted as Herzl's main representative in the negotiations, and together they hoped to gain de facto diplomatic recognition from Great Britain, making the proposal's political value immense. Despite East Africa's lack of moral and historical significance to Jews, the East Africa plan held the most promise compared to the other plans. Greenberg successfully obtained a letter from the Foreign Office expressing the British government's willingness to establish a Jewish colony with considerable land, local autonomy, and religious and domestic freedom under its general control. In the Sixth Zionist Congress, which took place in 1903 in Basel, Herzl presented the proposal and the Congress voted in favor of sending a fact-finding group to East Africa with 295 delegates in favor and 178 against.
