Background:
Nepal experienced a decade-long civil war that ended in 2006 with the signing of the Comprehensive Peace Agreement between the government and the Maoist rebels. This peace agreement paved the way for a more inclusive and democratic political system in Nepal.

Significant historical event:
The major earthquake in April 2015, which caused widespread destruction and loss of lives, served as a catalyst for the adoption of a new constitution in Nepal. The earthquake highlighted the urgent need for a stable and resilient political system that could effectively address the challenges faced by the country.

Adoption of a new constitution:
In September 2015, Nepal adopted a new constitution that replaced the Interim Constitution of 2007. The new constitution aimed to establish a federal democratic republic with a system of governance that ensured the representation and rights of all ethnic, religious, and marginalized groups in the country.
The new constitution also addressed issues such as federalism, secularism, and gender equality, which were key demands of various ethnic and marginalized groups in Nepal. It sought to decentralize power and ensure greater autonomy for provinces and local governments.

Impact:
The adoption of the new constitution in Nepal in 2015 marked a significant milestone in the country's transition to a more inclusive and democratic political system. It laid the foundation for a more stable and prosperous Nepal that could effectively address the needs and aspirations of its diverse population.
