Answer:
Religions and past beliefs systems have mostly been a disrupting element for development in India, the Middle East, and post-colonial Africa.
Step-by-step explanation:
The reason is mainly because in these areas of the world, diverging religions and past belief systems were lumped together in the country borders that former European colonial empires devised.
For example, in India, the British unified Muslims with Hindus and other Indian religions, but social conflict soon proved to be too disrupting, and this led to the separation of India and Pakistan.
In Syria, Christians, Sunni Muslims, and Shia Muslims were forced to live in the same country by the French. To this day, Syria keeps essentially the same borders, and the Syrian Civil War (still ongoing) is a testament to the problems that people of different religions and belief systems living together in the same space can cause to a country or region.
