Though the district came into existence in the mid of last
decade of 20th century, yet its antiquity is beyond any doubt. The earliest
inhabitants of the district were a primitive people using stone tools of
the lower palaeolithic age such as choppers, unworked flakes, cleavers,
hand-axes, etc. These have been discovered from Mansa Devi area (Bilaspur),
Pinjore and Suketri. In the ancient time Aryans traversed the region emotionally.
The district is also associated with Pandavas who enroute to Himalayas during
their exile stayed here for some times. The place was known as Panchpura
later corrupted to Pinjore. The name Panchpura was deciphered from the Pinjore
Baoli Inscription found from here. Pinjore is also mentioned in ancient
literature1. The region was also indirectly under the sway of the foreign
Kushan and Yaudhey rulers. This fact is corroborated from the recent finding
of Kushan bricks from the adjacent territories of present Ambala district.
According to Majumdar, this region had been a part of Gupta dynasty. This
fact is based on discovery of silver coins of Gupta dynasty.
Towards
the close of the seventh and first part of the eighth century A.D., the district
fell a prey to the imperial ambitions of Yasovarman of Kanauj and Lalitaditya,
the ruler of Kashmir. During the 12th century A.D., the area was acquired
by the Chauhans of Delhi. They restored peace and order in the area including
adjoining district of Ambala. The inscription , dated A.D. 1164 gives an idea
of the role which the region played in resisting the Muslim invaders. In this
context, it is said that Kilhana , maternal uncle of Prithviraj-II was appointed
as governor of Hansi and he defeated the ruler of Panchpura (Pinjore) and
extended Chauhan rule over that region. The district finally passed on to
the Muslim rule as a result of the decisive victory of Shihab-ud-din Ghuri
over Prithviraj -III in the Second Battle of Tarain (A.D. 1192). After the
death of Shihab-ud-din Ghuri, Qutb-ud-din Aibak established Muslim rule in
North India. The region was also included in the Delhi Sultanate. Tabakat-i-Nasiri
refers to the victories of Sultan Nasir-ud-din Mahmud in the vicinity of Pinjore
and the loot of the spoils from there.
After
Firuz's death, the region felt the full force of those intensive discords which
also disturbed Delhi-kingdom. Consequently, the adjacent territories and this
area went out of the control of Tughlaqs. The invasion of Timur(1398) destroyed
the whole countryside in the region upto Siwalik hills (possibly including Pinjore).
But his sway did not last a long period. Thereafter the area passed on the Mughals.
Akbar, the Great, had a vast area under his control including this region. Fidai
Khan, Aurangzeb's Master of Ordnance laid a beautiful garden at Pinjore. The
region was conquered by Rohillas but they were soon expelled by the Marathas.
The Marathas were badly run over by the British and major portion of this region
passed under the British in 1803. The area now forming part of Bilaspur village
about three kilometres of east of Manimajra was under the ruler of Manimajra.
The ruler of Manimajra (Gurbaksh Singh) got built the old shrine of Mata Mansa
Devi in 1815 A.D. The area now including Kalka was a part of erstwhile princely
State of Patiala but was acquired by the British in 1846. Later on it was included
in Simla district. After taking over the Chiefs of Ambala area under their protection,
the British controlled the affairs of all the states in the region in a most
effective manner through
political
agency at Ambala. The political agency of Ambala was transformed into Commissionership
under the Commissioner of Cis-Satluj States and the political supervision and
control over the States was intensified . By 1846, several chiefships had lapsed
owing to their failure to have male heirs and so called break-down of administrative
machinery. The British acquired strips of territory around of Ambala which was
included into Ambala district. By 1858, the whole of Haryana territory was a
part of the Punjab. The Kalka area, a part of Simla district, was transferred
to Ambala district in 1899. No change could be effected till 1966. Prior to
the formation of Haryana in November, 1966, Ambala district had six tahsils
but during the re-organisation it lost Nalagarh tahsil to Himachal Pradesh,
Rupnagar tahsil and major portion of Kharar tahsil to Punjab and a few villages
including the Chandigarh Capital Project Area to the newly formed Union Territory
Chandigarh .Ambala district retained only 3 tahsils -Ambala, Jagadhri and Naraingarh
including 153 villages and the Kalka town transferred from Kharar tahsil. Later,
in 1967, 153 villages and Kalka town were taken out of Naraingarh tahsil and
formed into a separate Kalka tahsil. There was no jurisdictional change during
the decade1971-81 with reference to the Kalka tahsil. The Ambala district experienced
jurisdictional changes during the decade1981-91. Panchkula tahsil was created
by transfering 77 villages of Kalka tahsil and 19 villages of Naraingarh tahsil
in October, 1989. Out of these 96 villages, four villages were fully merged
in Panchkula Urban Estate . The full-fledged Panchkula district came into existence
with effect from 15-8-1995. Now it had two tahsils Kalka and Panchkula.
