How it began
Nabulsi soap takes its name from Nablus, in the present-day State of Palestine. Handmade Palestine, a fair trade seller based there, says soap making has been practiced in the city for over 1,000 years. UNESCO describes it as a hand-crafted soap made from three natural, local ingredients: olive oil, water and lye. The sources do not name an inventor.
How it works
Locally pressed olive oil is mixed with water and an alkaline soda solution. In workshops the mixture is heated and stirred for days in large copper vats, then poured onto a clean floor to set. Workers cut the slab into bars by hand and stamp each with the mark of the family or workshop. UNESCO notes that the soap is made after the olive harvest and stored for a year before use.
How it spread
At its peak more than 30 factories in Nablus exported soap across the Arab world and beyond, according to Handmade Palestine. Elders also make small batches at home. UNESCO states that most families in Palestine share the tradition, with men and women taking part in all stages and children helping to cut and pack.
What lasted
The craft has provided income for families and tied soap making to the olive harvest and the land. Bars are given as gifts at weddings and birthdays. The family stamp turns each bar into a record of who made it. UNESCO says the skill passes through hands-on practice in farms, olive presses, families and small workshops.
Where it stands today
UNESCO inscribed the tradition of Nabulsi soap making in Palestine on the Representative List of the Intangible Cultural Heritage of Humanity in 2024. Handmade Palestine reports that the craft is under threat from conflict and from mass-produced alternatives, and that far fewer factories operate than at the peak.
