Bank for Israel under an agreement with the Jordanian authorities in the West Bank. In 1954, Israeli President Yitzhak Ben-Zvi fostered a Samaritan enclave in Holon, Israel, located in 15a Ben Amram Street. During Jordanian rule in the West Bank, Samaritans from Holon were permitted to visit Mount Gerizim only once a year, on Passover. In 1967, Israel conquered the West Bank during the Six-Day War, and the Samaritans there came under Israeli rule. Until the 1990s, most of the Samaritans in the West Bank resided in the West Bank city of Nablus below Mount Gerizim. They relocated to the mountain itself near the Israeli settlement of Har Brakha as a result of violence during the First Intifada (1987–1990). Consequently, all that is left of the Samaritan community in Nablus itself is an abandoned synagogue. The Israeli army maintains a presence in the area. The Samaritans of Nablus relocated to the village of Kiryat Luza. In the mid-1990s, the Samaritans of Kiryat Luza were granted Israeli citizenship. They also became citizens of the Palestinian Authority following the Oslo Accords. As a result, they are the only people to possess dual Israeli-Palestinian citizenship. Today, Samaritans in Israel are fully integrated into society and serve in the Israel Defense Forces. The Samaritans of the West Bank seek good relations with their Palestinian neighbors while maintaining their Israeli citizenship, tend to be fluent in Hebrew and Arabic, and use both a Hebrew and Arab name. Genetic studies Demographic investigation Demographic investigations of the Samaritan community were carried out in the 1960s. Detailed pedigrees of the last 13 generations show that the Samaritans comprise four lineages: The priestly Cohen lineage from the tribe of Levi. The Tsedakah lineage, claiming descent from the tribe of Manasseh The Joshua-Marhiv lineage, claiming descent from the tribe of Ephraim The Danafi lineage, claiming descent from the tribe of Ephraim Y-DNA and mtDNA comparisons Recently several genetic studies on the Samaritan population were made using haplogroup comparisons as well as wide-genome genetic studies. Of the 12 Samaritan males used in the analysis, 10 (83%) had Y chromosomes belonging to haplogroup J, which includes three of the four Samaritan families. The Joshua-Marhiv family belongs to Haplogroup J-M267 (formerly "J1"), while the Danafi and Tsedakah families belong to haplogroup J-M172 (formerly "J2"), and can be further distinguished by the M67 SNP—the derived allele of which has been found in the Danafi
