[1][2] He is an Orthodox Jew originally from Boston[3] who now lives in the Jewish community of Hebron in Tel Rumeida with his wife and nine children.

[6] Marzel was born in 1959 in Boston, Massachusetts, and emigrated to Israel with his family when he was 6 weeks old, settling in Jerusalem's Bayit Vegan neighbourhood.

Although his father Shlomo was a respected educator who did not deal much with politics, Baruch joined Kahane's Jewish Defense League at age 13.

During the election campaign, Marzel called on the Israeli military to "carry out a targeted killing against (left-wing figure) Uri Avnery and his leftist collaborators".

[13] In 2013, Marzel ran for the Knesset again, this time on the third slot of the newly founded Otzma LeYisrael party, which splintered from National Union.

In August 2012, Israeli police arrested Baruch Marzel at the entrance to the town of Kiryat Arba over his failure to report for questioning.

The telephone won't stop ringing, and on the other end, human scum who follow Marzel continue to curse and threaten.

"[26] In March 2015, six days before the 2015 legislative election, the Judea-Samaria District Police filed charges in the Jerusalem Magistrate's Court alleging that Marzel attacked a Palestinian Arab in 2013.

[29] In February 2017, Marzel was arrested after clashing with police while protesting the demolition of Amona, a Jewish settlement in the West Bank.

He led protests against the eighth Jerusalem Gay Pride parade of 2010, opining that "[homosexuality] is a disease of choice, and a man can change his taste and his ways.

[34] In 2006, Marzel sent an open letter to Linor Abargil, asking her not to marry non-Jewish Lithuanian NBA player Šarūnas Jasikevičius.

[35] A similar open letter was addressed in March 2010 to Israeli model Bar Refaeli, urging her not to marry her non-Jewish boyfriend at that time, American actor Leonardo DiCaprio.

[40] In 2000, Marzel organized a Purim party at the grave of Baruch Goldstein, the religious extremist who perpetrated the 1994 Cave of the Patriarchs massacre.

[42][43] On July 15, 2024, the EU added Baruch Marzel to its list of sanctioned individuals for "openly calling for an ethnic cleansing of the Palestinians, together with Ben-Zion “Bentzi” Gopstein, founder and leader of the extremist organisation Lehava, and Isaschar Manne, founder of the unauthorised Manne Farm outpost in the South Hebron Hills.
