South Asia Realm: The 8 Countries Defining the Region

South Asia (the Indian Subcontinent) comprises 8 sovereign states sharing tectonic, cultural, and historical coherence:

Regional Organizations

• SAARC (South Asian Association for Regional Cooperation): All 8 members (founded 1985) — largely moribund due to India-Pakistan tensions
• BIMSTEC: Bay of Bengal initiative (excludes Pakistan, Afghanistan)
• SCO: India, Pakistan observers; Afghanistan not member

Defining Characteristics

• Tectonic: Indian Plate collision → Himalayas, seismicity
• Monsoon: Shared climate engine (Jun-Sep)
• Rivers: Indus, Ganges, Brahmaputra — transboundary waters
• Culture: Dharmic religions (Hinduism, Buddhism, Jainism, Sikhism) + Islam
• Scripts: Brahmic family (Devanagari, Bengali, Gurmukhi, Sinhala, etc.)

Debated Inclusions

Sometimes included: British Indian Ocean Territory (Chagos), Tibet (cultural), Myanmar (ASEAN but cultural links). Afghanistan's inclusion is standard geographically but contested culturally.
