Rajiv Gandhi was assassinated in 1991 in Tamil Nadu's Sriperumbudur.
Rajiv Gandhi was a true patriot and a liberal, and "I''m proud to be his son", Congress leader Rahul Gandhi said as he paid tributes to the former prime minister on his 29th death anniversary.
"I am proud to be the son of a true patriot, liberal and a benevolent father. As Prime Minister, Rajiv ji had pushed India on the path of progress. He took many important steps to empower the country with his forward-looking vision. Today, on his death anniversary, I salute him with affection and gratitude," Rahul Gandhi tweeted in Hindi.
His sister Priyanka Gandhi Vadra put out her "last photo with father" before his death in 1991. Priyanka Gandhi was 19 at the time.
"To be kind to those who are unkind to you; to know that life is fair, no matter how unfair you imagine it to be; to keep walking, no matter how dark the skies or fearsome the storm; to nurture a strong heart, and fill it with love no matter how great it''s sorrows; these are the gifts of my father''s life," she tweeted.
Rajiv Gandhi's party, the Congress, also shared a small video of him on Twitter this morning.
"The man who felt the pulse of a young India & steered us towards a brighter future. The man who understood the needs of the young & old and was loved by one and all," it said.
Rajiv Gandhi dedicated his life towards empowering women and advocating for a more equal society, it said in another tweet.
The Congress said it has decided not to issue advertisements in his memory and instead utilise the money in helping migrants.
In his tribute, Congress General Secretary KC Venugopal remembered Rajiv Gandhi as a visionary and a caring and a kind human being.
"Rajiv Gandhi, youngest PM of India, was a visionary like no other. He was caring, loving & a kind human being. He envisioned & worked towards a brighter future for all Indians. As we remember him today, may he continue to inspire many more generations," he tweeted.
Rajiv Gandhi took over the charge of the Congress in 1984 following the assassination of his mother and then Prime Minister Indira Gandhi. He became India's youngest Prime Minister at the age of 40.
