The document discusses the origins and evolution of the G20. It began as informal consultations among finance ministers and central bank governors in 1999 in response to global economic crises that were affecting an increasing number of countries. As the 2008 financial crisis grew in scope and severity, the G20 emerged as a forum that could coordinate a global response, given that it included systemically important developed and emerging economies representing about 85% of global GDP. The first G20 Leaders' summit was convened in 2008 by President Bush to address the crisis. Subsequent summits have focused on restoring global economic stability and growth.
