Ruhama was first established in 1911, on land purchased in the same year by the "Remnant of Israel" (Hebrew: שארית ישראל) company, set up by Russian Jews in Moscow, under the leadership of Simon Velikovsky, the father of Immanuel Velikovsky, to invest money in Jewish agricultural settlements in the Land of Israel. The name derives from the Biblical book of Hosea, verse 1:6 and from the verse: " "And I will have mercy upon her that had not obtained mercy" (Hos. 2:23)". "An artesian well was dug in 1912, and a rather plentiful supply of water was found at a depth of fifty meters." The group also included members of the socialist Zionist movement Hashomer Hatzair. However, the initial settlers were expelled by the Ottoman Empire in 1917; a dilapidated museum building is all that is left of that original settlement.
However, the artesian well prompted the Allied forces under General Allenby to select Ruhama as their headquarters from which base "the British Army and the Jewish-American Legion conquered Palestine".
HaShomer used the Ruhama farm as its main forward base along the Gaza-Beersheva line.
Two subsequent attempts to re-establish the settlement during the period of the British Mandate were curtailed by the Arab riots in 1929 and 1936. The kibbutz was eventually successfully re-established in 1944, and grew to a population of 399.
The economy is based on four agricultural branches: field crops, irrigated cultivation, orchards and henhouses, but agricultural crops do not generate enough income to support the kibbutz, so to earn a living, many of Ruhama's members have taken jobs outside the kibbutz.
Like many kibbutzim, Ruhama went through a process of privatization in the late 1990s.
The kibbutz operates a factory which produces brushes, including toothbrushes, which are exported. In 1984, Ruhama established a PCB design company.
Ruhama has a full-care center for elderly patients, with about 25 beds, attending to patients suffering from Alzheimer's disease, Parkinson's disease, dementia, paralysis and stroke. With membership dropping from 350 members to 210, upkeep of the senior care center has meant self-taxation and general belt tightening on the kibbutz.
A symbol of how greatly times have changed, the kibbutz cut community services like the dining room, so that every family now cares for itself.
Atar Ha-Rishonim, or The Negev Pioneers, just outside the fence surrounding the kibbutz, is where the first Jewish settlers in modern times settled in the Negev. The site includes several buildings and a well, as well as farming tools used almost 100 years ago.
