Southern Asia 1925: Soviet Reorganization of Central Asia
The Soviet victory in Central Asia had brought the former Russian protectorates of Khiva and Bukhara under Soviet control, but also provoked revolts among the Central Asian peoples. By 1924 these revolts had been crushed, allowing the Soviets to assert their authority over the region and abolish the semi-independent Soviet Republics which had succeeded Khiva and Bukhara. In their place, the Soviets began reorganizing Central Asia along ethnic lines, starting with new Uzbek and Turkmen Soviet Socialist Republics.

British Protectorates in the Persian Gulf
The British Residency of the Persian Gulf maintains British India influence in a number of Gulf states. These states are nominally independent - and shown as such in most atlases from the period - but have all signed treaties guaranteeing British control over their foreign affairs.
The Sultanate of Muscat and Oman is the only one of these states with significant international relations, having obtained trade agreements with the US and France before it signed its treaty with Britain. Maps of the time often show Trucial Oman and even Qatar as regions of Oman.
Trucial Oman is the region to the west of Oman which collectively signed treaties with Britain. The sheikhdoms of this region are often called the Trucial States, and will become the United Arab Emirates. However at this time they have little unity, with no regional council until 1952.
The British Indian Empire, also known as the British Raj, is comprised of a complex of presidencies, provinces, protectorates, and agencies. Only the top level subdivisions are shown here.
The area under direct British rule is known as British India and made up of presidencies and provinces - a presidency simply being the name for an older province.
Outside British India, but often included within the sphere of the presidencies/provinces, are the hundreds of protectorates or 'princely states'. These are indirectly ruled states, the largest being Hyderabad, Kashmir, and Mysore. The others are either collected into agencies - which may in turn contain other smaller agencies - or fall under the sway of the provinces.
