Kach and its offshoot Kahane Chai (Hebrew for "Kahane Lives"). Former members founded the Kahane Movement.

Israel and West Bank settlements, particularly Kiryat Arba in Hebron and Kfar Tapuach. There have also been limited operations in the United States.

Kach and Kahane Chai seek the restoration of the biblical state of Israel. Both groups seek to expand Jewish rule over the West Bank and to expel Arabs from these territories. Additionally, they seek to establish Israel as a formal theocracy, ruled by Jewish law.

It is believed the two groups have an overlapping central membership of several dozen. Sympathizers are thought to number in the hundreds.

Both groups receive support from sympathizers in Europe, Israel and the United States. The groups have been known to work with other Jewish extremists, such as Revava and the Temple Mount Faithful.

Though Kach and Kahane Chai have been directly linked with few terrorist incidents, the groups have refused to condemn and sometimes applauded attacks against Arabs and other extremist actions taken by Kahanist sympathizers. One such example was the 1994 machine gun attack by Baruch Goldstein against the Ibrahimi Mosque in Hebron.
 
Some members have been arrested for several "low-level attacks" since 2000.
 
The group is noted for threats against Arabs and Israeli government officials. Members have also sought to destroy Jerusalem's Al-Aqsa Mosque.

Israeli-American Rabbi Meir Kahane founded the Kach (Hebrew for "Only Thus") movement in the late 1960s in Israel. The movement is the descendent of Kahane's Jewish Defense League, which was founded in the U.S. in 1968 to fight black anti-Semitism. Kahane moved to Israel in 1969 and spoke out against black Jews in Dimona in the Negev Desert. He also called for the expulsion of Arabs from Israel.
 
During the 1970s, the Kach movement attempted to win a seat in the Israeli Knesset. Kahane was elected in 1984, but was banned from the Knesset after a law was passed barring racist groups from participating in the legislature.
 
Kahane was sentenced to six months in prison in 1980 after plotting to destroy the Al-Aqsa Mosque in Jerusalem.
 
An Egyptian Islamic militant murdered Kahane in New York in 1990. Two militant groups took over after Kahane's death: Kahane Chai, led by his son Binyamin Kahane, and Kach, led by Baruch Marzel. Binyamin and his wife were assassinated in 2000.
 
A Kach supporter, Baruch Goldstein, killed 29 Muslims in a mosque in the West Bank in February 1994. A month later, the Israeli government banned Kach and Kahane Chai, designating them as terrorist organizations.
 
Kahane Chai increased its activity against Prime Minister Ariel Sharon's plans to dismantle Jewish settlements in the Gaza Strip and West Bank. Warnings were issued against politicians and threats made to derail trains. No violent acts took place.
 
The groups formally disbanded in 2005 after failing to persuade the Israeli government to lift its ban. However, former members and supporters likely continue to pursue the same goals. Some founded the advocacy group the Kahane Movement, which the State Dept. lists as an alias for Kahane Chai/Kach. The Kahane Movement consists of several groups in Israel, including the Kach Party, Kahane Chai, National Jewish Front and G'dud Haivri (Jewish Legion), as well as the Jewish Defense League and the Jewish Defense Organization in the U.S.

Baruch Marzel and Itamar Ben-Gvir, another former Kach leader, founded the Jewish National Front political party in January 2004.
