India gained independence on August 15, 1947, and the state of Himachal Pradesh was formed on April 15, 1948. Before independence, there was a historical context of the geographical trends of present Himachal Pradesh. Many small and big princely states and Thakurayas were located in this region and each state had its own constitutional rules and laws, which became part of the constitutional development of the Republic of India after independence. Even after the country gained independence, many princely states continued to dominate Himachal Pradesh. After attaining independence, these princely states made many efforts for the integrity and unity of the country. In this way, before the creation of a complete and separate state, the dominance of the native princely states continued to increase in Himachal Pradesh. These princely states started forming their own organizations and these organizations later transformed into the form of Prajamandal.

Himachal was formed on 15 April 1948 after India became independent. Durga Singh, the king of Baghat state, organized the Solan seminar which ran from 26 January 1948 to 28 January 1948, of which Durga Singh was the chairman. During this time, all the princely states of Shimla participated in the Solan seminar. It was agreed in the seminar that all the princely states would have to be merged if Himachal Pradesh had to be made a state. But the king of some Princely States does not agree with this. It is decided by the leaders that Satyagraha will be conducted in whichever princely state does not agree to join Himachal.

The Suket state, whose king was Lakshman Sen, did not agree with this decision. At that time the capital of Suket was Sunder Nagar. Satyagraha was carried out under the leadership of Padam Dev. On 18 February 1948, Pandit Padam Dev entered Suket with the revolutionaries. On 25 February 1948, he reaches Sunder Nagar and captures it. Raja Laxman Sen of Suket has to take the help of the Government of India.

But due to no legal action, Suket state was included in Himachal. Satyagraha was also carried out in the Chamba princely state. Chamba princely state also had to join Himachal. When Himachal Pradesh was formed on 15 April 1948, there were a total of 30 princely states in Himachal. Of which 26 were Mahasu princely states and the remaining 4 included Mandi, Suket, Chamba, and Sirmour.

On 15 April 1948, Himachal Pradesh became the chief commission province. N.C. Mehta became its first Chief Commissioner and first Deputy chief commissioner was appointed, EP Moon. It was decided by the Central Government that the chief commissioner will be appointed for only one year. The last chief commissioner was Bhagwan Sahay because, after 1951, Himachal Pradesh was made a part C state, At that time the area of Himachal Pradesh was 27,108 square kilometers . The population of Himachal Pradesh was 9,35,000. At that time there were 24 tehsils in Himachal Pradesh and 2 sub tehsils were Pangi and Bharmour, which was in Chamba . Anand Chand was the ruler of the princely state of Bilaspur. He refused to include Bilaspur in Himachal Pradesh. He wanted to make Bilaspur a separate state. Satyagraha movement was also carried out in the princely state of Bilaspur but this movement was also unsuccessful. No strict action was taken by the Government of India as the Bhakra Dam project was going on in Bilaspur at that time. After that on 15 August 1948 Bilaspur was made the Chief Commission Province. The first Chief Commissioner was Anand Chand and the second Deputy Commissioner was Chand Chhabra. Nalagarh was part of Himachal Pradesh, but the king of Nalagarh, Surendra Singh, had good relations with the Maharaja of Patiala, so he merged Nalagarh into Punjab. Thus Nalagarh becomes a part of Punjab. Nalagarh was earlier known as Hindoor. The people of Nalagarh did not want to join Punjab but their king went against the people and included Nalagarh in Punjab . From 1951 to 1956 Himachal Pradesh remained part C state. The Chief Commissioner was replaced by a Lieutenant Governor. The first Lieutenant Governor of Himachal Pradesh was Major General Himmat Singh. Now elections were possible in Himachal Pradesh because Himachal Pradesh was part C state. Elections were held for the first time in Himachal Pradesh in 1952. At that time, elections were held in a total of 36 assembly seats in Himachal Pradesh. The Congress won 24 seats. Yashwant Singh Parmar was the first Chief Minister of Himachal Pradesh. The first Chief Secretary was K.L. Mehta. Bilaspur was included in Himachal Pradesh on 1 July 1954 by an order of the Government of India. Bilaspur was included in Himachal Pradesh as the fifth district. Now there are 5 districts in Himachal Pradesh. The area of Himachal Pradesh was now 28,186 sq km. There were 41 seats in the assembly. The State Re-organisation Commission was set up in 1953. In 1954, this commission came to Himachal Pradesh. There are 3 members of this commission, Syed Faisal Ali, is also the chairman of this commission. The other two members are H.N. Kunzru and K.M. Panikkar. The report of this commission for Himachal Pradesh came in 1956. In which, H.N. Kunzru, says that Himachal Pradesh should join Punjab. K.M. Panikkar, says that Himachal Pradesh should join Punjab but Syed Fasal Ali, says that Himachal Pradesh should be made a state.

Thereafter, Himachal Pradesh remained a Union Territory from 1956 to 1971. Bajrang Bahadur was the first and Bahadur Singh was the last Lieutenant Governor of Himachal Pradesh. At that time the Territorial Council was formed by the Government of India in 1957, whose work was to look after the administration in Himachal Pradesh. The chairman of the Territorial Council was Thakur Karm Singh, a resident of Mandi.

Then, on 1 May 1960, Kinnaur was included in Himachal Pradesh as the sixth district, comprising 14 villages from Rampur Tehsil and Chini Tehsil from Mahasu District. Now Kinnaur district consists of three tehsils, Nichar, Kalpa, and Sangla. Legislative Assembly elections were held in Himachal Pradesh for the second time in 1963. Yashwant Singh Parmar of the Congress will be the Chief Minister for the second time. In 1965, the Punjab State Re-organisation Committee was constituted. It was also known as the Hukum Singh Committee. Hukum Singh was its chairman. By this Committee, on 1st November 1966, 4 districts were included in Himachal Pradesh from Punjab, Kangra, Kullu, Lahaul Spiti and Shimla. Now there were a total of 10 districts in Himachal Pradesh. The area of Himachal Pradesh was now 55,673 square km. In 1973, Kangra district was reorganized into three districts as Kangra, Una, and Hamirpur. Now Himachal Pradesh has a total of 68 Vidhan Sabha seats and 12 districts in total. Though its status remained that of a Union Territory. On 24th January 1968 Himachal Pradesh demanded to be a State. On 18th December 1970, the State of Himachal Pradesh Act was passed by Parliament and the new state came into being on 25th January 1971, declared by the Prime Minister of India Mrs. Indira Gandhi from the historic Ridge Maidan. Thus H.P. emerged as the eighteenth state of the Indian Union.
