Central Asia is considered as the origin of human race. The process of inter-mixing of two races was worked out in this region. Often, every new race which developed in this area, pushed out the people of old races. Due to this cause, ancient migration took place. Ancient migration in the world has been divided at the basis of different areas in the following classes:

1. Migration worked out from Asian countries. 

2. Migration worked out from European countries. 

3. Migration worked out from African countries.

1. Asian Migration: Asia has been considered the origin point of human race. Migration of people took place from here due to a fundamental change in climate. Moreover, the old races were driven out by the new developed races. 

The pattern of Asian migration is seen in three areas :

(a) From China: Before the 20th century, many people left China and settled in Manchuria, Korea, Malaysia, Thailand, Indonesia, Vietnam, Philippines.

(b) From Japan: During the years 1880-1900, a large number of Japanese shifted to Hawaiian Islands, United States Nations of America, Canada, Brazil, Australia, Manchuria, Korea and Malaysia. The main cause of their movement was the pressure of increasing population in Japan.

(c) From India: The movement of people from India has been taking place towards the nearby countries, Myanmar, Sri Lanka, Malaysia, Indonesia, for religious, propagation. During British rule in India, a large number of Indians were sent to Mauritious, Fiji, Trinidad, as captive labourers.

2. Migration From Europe: The movement from European countries was due to the lack of resources and low living standard in this continent. 

The movement of people from Europe was made towards two main areas:

• Towards Tropical climate zones. 
• Towards Temperate climate zones.

Tropical Climate Zones: Europeans made their movement towards the tropical climate zones, i.e., to the coastal areas of North America and South America. They also migrated to Asian tropical zones where plantation of cotton, sugarcane, tobacco, coffee, tea and spices was suitable.

Temperate Climate Zones: The main cause of the movement of people towards this zones was the same climate and living condition as it was in Europe. The countries like United States of America, Canada, South America, New Zealand, have the same climate. So, a large number of Europeans migrated to these countries.

3. Migration from Africa: The movement of people from African countries took place towards the coastal areas of North America and South America.
