Southern Asia 1921: Greco-Turkish War
The most serious conflict in Turkey's war for independence was the Greco-Turkish War. In 1919 Greece had moved troops into western Anatolia to protect the sizeable local Greek population and assert its historical claim over the region. By August 1921 the Greeks were within 80km of Ankara, but proved unable to break through the Turkish defenses and were eventually forced to withdraw.

British Protectorates in the Persian Gulf
The British Residency of the Persian Gulf maintained British India's influence in a number of Gulf states from the 19th Century until 1947. These states were nominally independent - and shown as such in most atlases from the period - but all signed treaties guaranteeing British control over their foreign affairs.
The Sultanate of Muscat and Oman was 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 was the region to the west of Oman which collectively signed treaties with Britain. The sheikhdoms of this region were often called the Trucial States, and later became the United Arab Emirates. However at this time they had little unity, with no regional council until 1952.
The British Indian Empire, also known as the British Raj, was comprised of a complex of presidencies, provinces, protectorates, and agencies. Only the top level subdivisions are shown here.
The area under direct British rule was 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, were the hundreds of protectorates or 'princely states'. These were indirectly ruled states, the largest being Hyderabad, Kashmir, and Mysore. The others were either collected into agencies - which might in turn contain other smaller agencies - or fell under the sway of the provinces.

The invading Greek army advanced on the Turkish Nationalist lines on the Sakarya River, 80km from the Nationalist capital of Ankara. By September 2, the Greeks had captured Mount Chal and in the ensuing 10 days, some units come within 50km of Ankara. However, the Greeks were overextended, and a Turkish counterattack on September 8 forced them to abandon the offensive and withdraw toward Eskişehir and Kara Hisar.
