In 1921, Tagore and agricultural economist Leonard Knight Elmhirst had set up the Institute for Rural Reconstruction (which Tagore later renamed Shriniketan—"Abode of Wealth") in Surul, a village near the ashram at Santiniketan.

Through it, Tagore had sought to provide an alternative to Gandhi's symbol- and protest-based Swaraj movement, which he had denounced.

He had recruited scholars, donors, and officials from many countries to help the Institute use schooling to "free village from the shackles of helplessness and ignorance" by "vitaliz[ing] knowledge".

The British divide their West Asian mandate in two: east of the Jordan River becomes the Emirate of Transjordan, to be ruled by Abdullah, and west of the Jordan River becomes the Palestine Mandate.

Effectively, Turkish rule in Transjordan is simply replaced by British rule.

British Lieutenant Colonel Frederick Gerard Peake raises an internal police force, the Arab Legion, to keep order among Transjordanian tribes and to safeguard Transjordanian villagers from Bedouins.

The Amirate of Transjordan has fewer than four hundred thousand inhabitants at its inception in 1921.

Of this number, about twenty percent live in four towns each having populations of from ten thousand to thirty thousand.

The balance are farmers in village communities and pastoral nomadic and seminomadic tribespeople.

The amirate's treasury operates on British financial aid established on the basis of an annual subsidy.

To supplement the rudimentary police, in 1921 a reserve Arab force is organized by F. G. Peake, a British officer known to the Arabs as Peake Pasha.

This Arab force soon is actively engaged in suppressing brigandage and repelling raids by the Wahhabis.
