The Empire of India is a country in southern and central Asia.
India includes, more or less, OTL states of India, Pakistan, Bangladesh, Afghanistan, Tajikistan, Kyrgyzstan, Turkmenistan, and Uzbekistan, as well as parts of western China.
The Empire of India was a vassal state of the British Empire. The Emperor of India was the King of the United Kingdom, and was represented by a Viceroy.
During the Second Great War, First the Third Reich and then the Soviet Union offered support to the independentist movements in India, which were refused by the Congress Party. When the war between Britain and the Soviet Union started, Chamberlain accepted a plan to reinforce India and use it as a platform to attack Soviet Central Asia.
The Soviet Union soon collapse to the multi-front war, particularly by the Third Reich supported National Party of Russia, but Britain had also made important advances into Central Asia, and controlled Afghanistan, Tajikistan, Kyrgyzstan, Turkmenistan and Uzbekistan, mainly by use of Indian Muslim soldiers.
After the Fall of the Soviet Union, Britain was in a dilemma. Controlling Central Asia was a very huge effort, particularly if India were granted Independence. But the region was strategic to keep the new Russian Government to ally with the Third Reich. Furthermore, Central Asian territories were controlled by British friendly governments that demand the continuous presence of Britain to ensure them to keep both the Russian and the Fundamentalist to take control of their lands.
Britain increased the presence of Indian advisors in Central Asia, both Muslim and Hindu. Soon Central Asia, with the personnel from India and the resources of Britain, began to be Indianized.
The original plan to grant India independence in 1950, included the partition of India in two states, one for the Muslims and one for the Hindus, but this was opposed by the Indian Congress Party. Additionally the situation of Central Asia was unclear. According to the British, they were not yet prepared to self rule, and controlling those territories would be very difficult even if India were not independent. Finally India was granted undivided independence in 1950, inside the British Commonwealth, and Central Asia reminded as part of the British Empire. However local governments opposed that Indian military advisors would withdraw from their territories. In 1952, Britain transferred the control of Central Asia to the Delhi government.
India had a hard time to keep the religious conflict in India proper under control. Supporting Central Asia, whose status were as Protectorates of India, was a great effort. Additionally, when South China regained her independence to Japan, also became a threat to some Central Asian territories which either had ethnic Chinese in their populations or were once part of China. In 1956, India issued a new constitution, granting more power to the provinces while keeping a strong military force, promoting a more secular government, and respect to local customs, and offered the Central Asian nations to adhere to the new Constitution.
Threatened by either China, Russia, Kazakhstan or the Islamic Fundamentalism, into the next ten years each Central Asian territories, as well as Hindu, Islamic, Sikh and mixed states inside Indian Proper, adhered to the new Constitution.
The Constitution of India does not provide a title to the name of India. India is a Parliamentary Monarchy, and the terms Kingdom and Empire are widely used, however Federation might be more appropriate. Today India is a country of many contrasts. While the richer parts of the country are paired in technology and living standards to other leading countries in the World, India still have huge levels of misery. The most populous country in the World India is one of the leaders of Aerospacial and Computer technologies and a net exporter of manufactured goods. During the past few decades, Indian Central Asia had been particularly developed and integrated by high speed trains. Poverty, while still an important factor, has been decreasing.
