THULASENDRAPURAM, INDIA -- With chants of "Long live Kamala Harris," fireworks and prayers, residents of a tiny Indian village celebrated her inauguration as U.S. vice-president.

People flocked to the village and its Hindu temple in southern India, to watch Harris, who has ancestral roots in the village, take her oath of office on Wednesday in Washington.

Groups of women in bright saris and men wearing white dhoti pants watched the inauguration live as reporters broadcast the villager's celebrations to millions of Indians. The villagers chanted "Long live Kamala Harris" while holding portraits of her and blasted off fireworks the moment she took the oath.

Indian Prime Minister Narendra Modi called Harris becoming U.S. vice-president a "historic occasion. Looking forward to interacting with her to make India-USA relations more robust."

Earlier, the villages adorned their temple with flowers, offering special prayers for Harris' success. Her maternal grandfather was born in the village of Thulasendrapuram, about 350 kilometres (215 miles) from the southern coastal city of Chennai.

"We are feeling very proud that an Indian is being elected as the vice-president of America," said teacher Anukampa Madhavasimhan.

At the prayer ceremony in Thulasendrapuram, the idol of Hindu deity Ayyanar, a form of Lord Shiva, was washed with milk and decked with flowers by a priest. Then the village reverberated with the sound firecrackers as people held up posters of Harris and clapped their hands.

Harris made history Wednesday as the first Black, South Asian and female U.S. vice-president and what made her special for the village is is her Indian heritage.

Harris' grandfather was born more than 100 years ago. Many decades later, he moved to Chennai, the capital of Tamil Nadu state. Harris' late mother was also born in India, before moving to the U.S. to study at the University of California. She married a Jamaican man, and they named their daughter Kamala, a Sanskrit word for "lotus flower."

In several speeches, Harris has often spoken about her roots and how she was guided by the values of her Indian-born grandfather and mother.

So when Joe Biden and Harris triumphed in the U.S. election last November, Thulasendrapuram became the centre of attention in entire India. Local politicians flocked to the village and young children carrying placards with photos of Harris ran along the dusty roads.

Then and now, villagers set off firecrackers and distributed sweets and flowers as a religious offering.

Posters and banners of Harris from November still adorn walls in the village and many hope she ascends to the presidency in 2024. Biden has skirted questions about whether he will seek reelection or retire.

"For the next four years, if she supports India, she will be the president," said G Manikandan, who has followed Harris politically and whose shop proudly displays a wall calendar with pictures of Biden and Harris.

On Tuesday, an organization that promotes vegetarianism sent food packets for the village children as gifts to celebrate Harris' success.

In the capital New Delhi, there has been both excitement -- and some concern -- over Harris' ascent to the vice presidency.

Modi had invested in President Donald Trump, who visited India in February last year. Modi's many Hindu nationalist supporters also were upset with Harris when she expressed concern about Kashmir, the divided and disputed Muslim-majority region whose statehood India's government revoked last year.
