The nearby Palestinian village of Saffuriya had been almost emptied of its 4000 inhabitants in July 1948. By early January, 1949, about 500 villagers had filtered back, but "neighbouring settlements coveted Saffuriya lands". The "Northern Front" ordered their eviction, which was carried out the 7th of January 1949. The Saffuriya land was then distributed to its neighbouring Jewish settlements.
In February 1949, 1,500 Dunams of Saffuriya land was given to Sde Nahum.[1]
