Nepal's history stretches back to ancient times, with evidence of human habitation dating back to prehistoric eras. The Kathmandu Valley, which is the heart of the country, was one of the oldest continuously inhabited places in the world. Throughout history, Nepal was ruled by various kingdoms and empires, including the Licchavis, the Malla, and the Shahs.

• In the 18th century, the Shah dynasty came to power and established a central government in Nepal, and expanded its territory through conquests. During this period, the country developed a unique form of ruling and government system called Shah dynasty's ruling in which Nepal remained an absolute monarchy till 1990s.
• During the 19th century, Nepal was closed off from the outside world, and remained largely isolated from the major events taking place in the surrounding countries. Nevertheless, in 1951, the Rana dynasty was overthrown and Nepal adopted a new constitution and become a constitutional monarchy.
• In 1990, after a pro-democracy movement, Nepal become a parliamentary democracy and abolished the absolute monarchy system. Nepal has undergone significant political and economic changes since then, but it has faced some challenges, including a civil war between the Maoist rebels and the government, which lasted from 1996 until 2006.
• Since the end of the war and the integration of the Maoist fighters into mainstream politics, Nepal has been working to establish a stable and sustainable democratic system, however it still faces challenges such as political instability, poverty and lack of infrastructure development.
