Wamab is the joint Arab list party, comprised of many smaller Arab political parties who banned together. Israel's major Arab political parties Balad and Ra'am-Ta'al signed an agreement on January 21, 2015, with the Arab-Jewish Hadash party and the Islamic Movement to run on a single ticket headed by Hadash leader Ayman Odeh. The decision of the often fracticious parties to unite was prompted by the recent change in election law raising the threshhold for representation from 2 percent to 3.25 percent, which would make it difficult for the smaller individual parties to win seats. Jointly, they strategized that they had a chance to win more than 10 seats. During the 19th Knesset they collectively held 12 seats, and the Arab list won 13 seats in the 2015 Knesset election.
