There are several assumptions why the capital was moved: Naypyidaw is more centrally located than the old capital, Yangon. It is also a transportation hub located adjacent to the Shan, Kayah, and Kayin states. It was felt by governmental and military leaders that a stronger military and governmental presence nearby might provide stability to those chronically turbulent regions. Climate consideration could have also contributed to the capital transfer, since Yangon proved vulnerable to Cyclone Nargis, which killed over 100,000 people in Myanmar in May 2008. The official explanation for moving the capital was that Yangon had become too congested and crowded with little room for future expansion of government offices.
