Greater IndiaGreater India, also known as the Indian cultural sphere, the Indosphere, or the Indic world, is an area composed of many countries and regions in South and Southeast Asia that were historically influenced by Indian culture, which itself formed from the various distinct indigenous cultures of these regions. Specifically Southeast Asian influence on early India had lasting impacts on the formation of Hinduism and Indian mythology. Hinduism itself formed from various distinct folk religions, which merged during the Vedic and subsequent periods.

ChampaChampa (Cham: ꨌꩌꨛꨩ; ចាម្ប៉ា; Chiêm Thành 占城 or Chăm Pa 占婆) was a collection of independent Cham polities that extended across the coast of what is present-day central and southern Vietnam from approximately the 2nd century AD until 1832. According to earliest historical references found in ancient sources, the first Cham polities were established around the 2nd to 3rd centuries CE, in the wake of Khu Liên's rebellion against the rule of China's Eastern Han dynasty, and lasted until when the final remaining principality of Champa was annexed by Emperor Minh Mạng of the Vietnamese Nguyễn dynasty as part of the expansionist Nam tiến policy.
Spice tradeThe spice trade involved historical civilizations in Asia, Northeast Africa and Europe. Spices such as cinnamon, cassia, cardamom, ginger, pepper, nutmeg, star anise, clove, and turmeric were known and used in antiquity and traded in the Eastern World. These spices found their way into the Near East before the beginning of the Christian era, with fantastic tales hiding their true sources. The maritime aspect of the trade was dominated by the Austronesian peoples in Southeast Asia, namely the ancient Indonesian sailors who established routes from Southeast Asia to Sri Lanka and India (and later China) by 1500 BC.
