• The Quad (Quadrilateral Security Dialogue) is a strategic partnership involving India, Japan, Australia, and the United States. It was initially formed as a loose partnership following the 2004 Indian Ocean Tsunami.
• The countries came together to coordinate their humanitarian and disaster relief efforts after the devastating tsunami that affected countries in the Indian Ocean region, particularly Indonesia, Sri Lanka, India, and Thailand.
• Over time, the Quad evolved into a more formal security and strategic dialogue, focusing on issues like Indo-Pacific security, maritime stability, and economic cooperation.
