Nepal, officially the Federal Democratic Republic of Nepal, is a landlocked sovereign state located in South Asia. With an area of 147,181 square kilometres and a population of approximately 27 million, Nepal is the world's 93rd largest country by land mass and the 41st most populous country. It is located in the Himalayas and bordered to the north by the People's Republic of China, and to the south, east, and west by the Republic of India. Specifically, the Indian states of Uttarakhand, Uttar Pradesh, Bihar, West Bengal, and Sikkim border Nepal, while across the Himalayas lies the Tibetan Autonomous Region. Nepal is separated from Bangladesh by the narrow Indian Siliguri corridor. Kathmandu is the nation's capital and largest metropolis.The mountainous north of Nepal has eight of the world's ten tallest mountains, including the highest point on Earth, Mount Everest, called Sagarmatha in Nepali. It contains more than 240 peaks over 20,000 ft above sea level. The southern Terai region is fertile and humid. Lumbini, the birthplace of Lord Gautam Buddha, is located in this region. Lumbini is one of the holiest places of one of the world's great religions, and its remains contain important evidence about the nature of Buddhist pilgrimage centres from as early as the 3rd century BC.Hinduism is practiced by about 81.3% of Nepalis, making it the country with the highest percentage of Hindus. Buddhism is linked historically with Nepal and is practiced by 16%, Kirat 5.1%, Islam by 4.4%, Christianity 1.4%, and animism 0.4%. A large section of the population, especially in hill region, even though they follow Hindu customs, may identify themselves as both Hindu as well as Buddhists which can be attributed to syncretic nature of Hinduism and Buddhism in Nepal.A monarchy throughout most of its history, Nepal was ruled by the Shah dynasty of kings from 1768 , when Prithvi Narayan Shah unified its many small kingdoms, until 2008; a decade-long Civil War involving the Communist Party of Nepal (Now known as the Unified Communist Party of Nepal) and several weeks of mass protests by all major political parties led to the 12-point agreement of 22 November 2005. The ensuing elections for the constituent assembly on 28 May 2008 overwhelmingly favored the abolition of the monarchy and the establishment of a federal multiparty representative democratic republic.In recent developments, the political parties of Nepal have agreed on forming an interim government under the leadership of Chief Justice Khil Raj Regmi in order to hold Constituent Assembly elections by 19 November 2013 to end the political deadlock.The second election for the constituent assembly was held successfully and Sushil Koirala was appointed the new prime minister.In 2013, Nepal ranked the 157th place on the Human Development Index and is one of the least developed nations in the entire world.
