Formed in mid-2013, the group has been led by several members of the influential al-Jader family from the town of Jarabulus and the nearby town of Karkamış in Turkey.

The campaign was launched at the second half of 2012 and ended in the capture of the city of Raqqa as well as dozens of smaller towns and facilities.
The Battle of al-Yaarubiyah was fought in late October 2013 at al-Yaarubiyah, a strategically important town at the border of Syria with Iraq. Affiliates of the Democratic Union Party (PYD), namely the YPG/YPJ and local Arab tribes, attacked the settlement in an attempt to capture it from Jihadist and Islamist groups, led by the Al-Nusra Front and the Islamic State of Iraq and the Levant. After four days of heavy fighting, the Islamists were defeated and expelled from al-Yaarubiyah.
The Northern Democratic Brigade is a Free Syrian Army unit that is closely allied to the Syrian Kurdish YPG and YPJ in Afrin Region since 2014. Led by Absi Taha, Alexander Khalil, and Alexander Alaa, it also joined the Syrian Democratic Forces (SDF) in November 2015. The initial members of the group originated from Jabal Zawiya in Idlib, and it has recruited Arabs from Idlib, Aleppo, and other cities in northern Syria since allying with the YPG. Since joining the SDF, the unit has begun to operate across much of northern and eastern Syria, participating in operations against anti-SDF Syrian opposition factions, the Islamic State of Iraq and the Levant, the Turkish Armed Forces, and the Syrian National Army.

One of the most prominent pro-Turkish formations in the FSA, the group fought in the Battle of Aleppo (2012–2016) and other campaigns in Aleppo Governorate against the Syrian government, ISIL, and the SDF. The exact origin of the current Muntasir Billah Brigade is unclear, and it is possible that it originated as remnant of a rebel group that had been active in Raqqa Governorate until being subsumed by the al-Nusra Front and ISIL in 2013.
Opposition–ISIL conflict during the Syrian Civil War started after fighting erupted between Syrian opposition groups and the Islamic State of Iraq and the Levant (ISIL). In early January 2014, serious clashes between the groups erupted in the north of the country. Opposition groups near Aleppo attacked ISIL in two areas, Atarib and Anadan, which were both strongholds of the fundamentalist Sunni organization. Despite the conflict between ISIL and other rebels, one faction of ISIL has cooperated with the al-Nusra Front and the Green Battalion to combat Hezbollah in the Battle of Qalamoun. By 2018.
