Trade routes and imperialism from outside countries have been factors that led to a lot of Southeast Asian cities developing.

Trade routes facilitated the exchange of goods, ideas, and cultures, leading to the growth of urban centers along these routes. Southeast Asia has historically been a hub of maritime trade, connecting East Asia, South Asia, and the Middle East. This has resulted in the establishment and growth of port cities such as Singapore, Manila, and Bangkok.

Imperialism from outside countries, including European powers like the Portuguese, Dutch, Spanish, British, and French, led to the colonization and urbanization of Southeast Asian cities. These colonial powers established administrative centers, ports, and trading posts, which later developed into major cities. Examples include Jakarta, Ho Chi Minh City, and Kuala Lumpur.
