Puducherry (union territory) replaces French India
Puducherry (), also known as Pondicherry (; French: Pondichéry), is a union territory of India, consisting of four small geographically unconnected districts. It was formed out of four territories of former French India, namely Pondichéry  (Pondicherry; now Puducherry), Karikal (Karaikal), Mahé and Yanaon (now Yanam), excluding Chandannagar (Chandernagore), and it is named after the largest district, Puducherry, which was also the capital of French India. Historically known as Pondicherry (Pāṇṭiccēri), the territory changed its official name to Puducherry on 20 September 2006.The Union Territory of Puducherry lies in the southern part of the Indian Peninsula. The areas of Puducherry district and Karaikal district are bound by the state of Tamil Nadu, while Yanam district and Mahé district are enclosed by the states of Andhra Pradesh and Kerala, respectively. Puducherry is the 29th most populous of the 36 states and union territories of India, and the third most densely populated union territory. It has a gross domestic product (GDP) of ₹210 billion (US$2.6 billion) and ranks 25th in India.History
The earliest recorded history of the municipality of Puducherry can be traced to the second century CE. The Periplus of the Erythraean Sea mentions a marketplace named Poduke or Poduka (ch 60). G. W. B. Huntingford suggested this might be a site about 2 miles from the modern Puducherry, which was possibly the location of Arikamedu (now part of Ariyankuppam). Huntingford noted that Roman pottery was found at Arikamedu in 1937. In addition, archaeological excavations between 1944 and 1949 showed that it was "a trading station to which goods of Roman manufacture were imported during the first half of the 1st century" Subsequent investigation by Vimala Begley from 1989 to 1992 modified this assessment, and now place the period of occupation from the third or second century BCE to the eighth century CE.In 1674, the municipality of Pondicherry (Pondichéry) became a French colony in the French colonial empire. Together with Chandernagor (already French since 1673), Mahé (since 1721), Yanam (Yanaon) (since 1723), Karaikal (Karikal) (since 1739) and Masulipatam (1760), it formed the colony of French India, under a single French governor in Pondicherry, although French rule over one or more of these enclaves was repeatedly interrupted by British occupations. The territories of French India were completely transferred to the Republic of India de facto on 1 November 1954, and de jure on 16 August 1962, when French India ceased to exist, becoming the present Indian union territory of Pondicherry, combining four coastal enclaves. The fifth, Chandannagar, merged with the state of West Bengal in 1954. Immediately after the de facto transfer, the area was renamed the 'State of Pondicherry' by the “French Establishments (Change of Name) Order, 1954” issued by the Ministry of External Affairs of India.: 37  The State of Pondicherry continued to be under the direct control of Government of India under the aegis of the Ministry of External affairs until 31 August 1964. Meanwhile, with effect from 1 July 1963, the State of Pondicherry officially became the Union Territory of Pondicherry and after 31 August 1964 it came under the control of the Ministry of Home Affairs.: 37 Until 2016, the de jure transfer day (i.e. 16th of August) was a public holiday with no official celebrations taking place. In 2016, Lt. Governor of Puducherry, Kiran Bedi, made it a holiday as “De Jure Transfer Day.”
Since 2010, de facto transfer day (i.e. 1st of November) has been celebrated as Liberation day throughout Puducherry. In 2014, Liberation day was declared as a public Holiday. This initiative was taken shortly after the NDA government came to power in 2014 and newly appointed Lt. Governor A. K. Singh issued a notification regarding that decision of the central government.
