Nepal is a landlocked country in South Asia. It is bordered by the People's Republic of China to the north and by India to the south, east and west. The Himalaya mountain range runs across Nepal's northern and western parts, and eight of the world's ten highest mountains, including the highest, Mount Everest, lie within its borders. Until 2006, Nepal was a kingdom. On December 28, 2007, the Interim Parliament passed a bill and declared Nepal to be a Federal Democratic Republic.
