The former village development committee (VDC) was converted into a municipality on 18 May 2014 by merging the existing Sandhikharka, Wangla, Narapani, Khanchikot, Kimadada, Argha and Dibharna VDCs.

Sandhikharka has made a significant progress in road building and the training of people through various national and international non-governmental organisations.

Development of new houses, privately own luxury vehicles and the modern atmosphere itself have shown that the town has marvellously progressed in terms of economy and other sectors.

On September 8, 2002, the town was involved in a massive battle between the government forces and "thousands" of Maoists, reportedly led by the two most wanted terrorists of that time Top Bahadur Rayamajhi and Pampha Bhusal who come from the district.

[6] A telecommunication tower was destroyed as a result of the second attack,[7] and reinforcements were rushed in by helicopter as well as a government-sponsored effort to hold the town.

[4] CNN speculated that these attacks were aimed at disrupting the upcoming election by forcing the Nepali government to impose a state of emergency.

[9] After forcing rebels into retreat, the military recovered "some crude bombs, terrorist documents and equipment used to operate mines".

[9] Nepal's military released a statement on the fighting: On 4 March, terrorists... fled after strong resistance by the security forces.

"'Panini Multiple Campus"' is the first and oldest college affiliated by Tribhuvan university in this district which is founded by Mr. Gyan Hari Acharya.

[3] According to schoolchild Pratiba Acharya, "Maoists thought that only rich people study in boarding schools like mine, so they want to close them.

For one thing, Nepali, though widely spoken and understood, is not invariably the mother tongue of all students in multilingual, multi-ethnic Nepal.

In doing so, the VDC gives village people an element of control and responsibility in development, and also ensures proper utilization and distribution of state funds and a greater interaction between government officials, NGOs and agencies.

The village development committees within a given area will discuss education, water supply, basic health, sanitation and income and will also monitor and record progress which is displayed in census data.
