Early History
Modern Nepal was created in the latter half of the 18th century when Prithvi Narayan Shah, the ruler of the small principality of Gorkha, formed a unified country from a number of independent hill states. The country was frequently called the Gorkha Kingdom, the source of the term "Gurkha" used for Nepali soldiers. After 1800, the heirs of Prithvi Narayan Shah proved unable to maintain firm political control over Nepal. A period of internal turmoil followed, heightened by Nepal's defeat in a war with the British from 1814 to 1816. Stability was restored after 1846 when the Rana family gained power, entrenched itself through hereditary prime ministers, and reduced the monarch to a figurehead.
The Rana regime, a tightly centralized autocracy, pursued a policy of isolating Nepal from external influences. This policy helped Nepal maintain its national independence during the colonial era, but it also impeded the country's economic development. In 1950, King Tribhuvan, a direct descendant of Prithvi Narayan Shah, fled his "palace prison" to newly independent India, touching off an armed revolt against the Rana administration. This allowed the return of the Shah family to power and, eventually, the appointment of a non-Rana as prime minister.

A period of quasiconstitutional rule followed, during which the monarch, assisted by the leaders of fledgling political parties, governed the country. During the 1950s, efforts were made to frame a constitution for Nepal that would establish a representative form of government, based on a British model.
Democracy Develops
In early 1959, King Mahendra issued a new constitution, and the first democratic elections for a national assembly were held. The Nepali Congress Party, a moderate socialist group, gained a substantial victory in the election. Its leader, B.P. Koirala, formed a government and served as prime minister.
Declaring parliamentary democracy a failure 18 months later, King Mahendra dismissed the Koirala government and promulgated a new constitution on December 16, 1962. The new constitution established a "partyless" system of panchayats (councils) which King Mahendra considered to be a democratic form of government closer to Nepalese traditions. As a pyramidal structure progressing from village assemblies to a Rastriya Panchayat (National Parliament), the panchayat system enshrined the absolute power of the monarchy and kept the King as head of state with sole authority over all governmental institutions, including the Cabinet (Council of Ministers) and the Parliament. King Mahendra was succeeded by his 27 year-old son, King Birendra, in 1972.
Amid student demonstrations and anti-regime activities in 1979, King Birendra called for a national referendum to decide on the nature of Nepal's government--either the continuation of the panchayat system with democratic reforms or the establishment of a multiparty system. The referendum was held in May 1980, and the panchayat system won a narrow victory. The king carried out the promised reforms, including selection of the prime minister by the Rastriya Panchayat.
Movement To Restore Democracy
In 1990, the political parties again pressed the king and the government for change. Leftist parties united under a common banner of the United Left Front and joined forces with the Nepali Congress Party to launch strikes and demonstrations in the major cities of Nepal. This "Movement to Restore Democracy" was initially dealt with severely, with more than 50 persons killed by police gunfire and hundreds arrested. In April, the king capitulated. Consequently, he dissolved the panchayat system, lifted the ban on political parties, and released all political prisoners.
An interim government was sworn in on April 19, 1990, headed by Krishna Prasad Bhattarai as prime minister presiding over a cabinet made up of members of the Nepali Congress Party, the communist parties of Nepal, royal appointees, and independents. The new government drafted and promulgated a new constitution in November 1990, which enshrined fundamental human rights and established Nepal as a parliamentary democracy under a constitutional monarch. International observers characterized the May 1991 elections as free and fair in which the Nepali Congress won 110 seats out of 205 to form the government. The 1994 elections resulted in a Nepali Congress defeat and a hung Parliament, with a minority government led by the United Marxist and Leninist Party (UML).

The next 5 years saw five successive governments. Although the Nepali Congress won a clear majority (113 out of 205) in the latest parliamentary elections, held in 1999, the pattern of short-lived governments persists, with three different Nepali Congress Party Prime Ministers holding office from mid-1999 to mid-2001.
