In an era long before this age of instant connect of mobile phones and internet, Rajesh Khanna was the man who sparked a frenzy never seen before and never since, not even by the likes of Amitabh Bachchan.

Rajesh Khanna's very name spelt magic in the 1970s. He sparked hysteria, particularly amongst his legions of women fans, who would line the road for a glimpse, chant his name, cover his car with lipstick marks and even write him letters in blood. They got married to his photograph, cut their finger, let the blood flow and applied 'sindoor'.

Kaka, as he was popularly known, was one of the highest-paid actors of his time, his record of consecutive solo super hits still unbroken.

In picture: Rajesh Khanna and Dimple Kapadia maintained an amicable relationship where they both were seen together at parties and family functions. Kapadia also campaigned for Khanna's election and worked in his film 'Jai Shiv Shankar' (1990).

Who can forget the years between 1970-1979 when he starred in mega hits like Safar, Kati Patang, Sachaa Jhutha, Aan Milo Sajna, Anand, Amar Prem and Mere Jeevan Saathi. Ever the urbane, suave romantic who wooed like few others.

Glory and fame galore came his way with the two 1969 films - Aradhana and Do Raaste - where he teamed up with two of his best co-stars, Sharmila Tagore and Mumtaz, respectively. Both the films were super hits. Hindi film's first superstar was born.

Rajesh Khanna had 15 consecutive solo hit films between 1969 and 1971. Between Aradhana in 1969 and Prem Kahani in 1975, Rajesh enjoyed god-like status.

It was all about charisma - a certain something that went beyond the art of acting. He had that unique way of delivering dialogue, of crinkling his eyes and that interesting head tilt that was all his own - and designed to get fans swooning.

Describing the charm of Rajesh Khanna, Amitabh once said: 'I got famous purely because I was working with Rajesh Khanna in 'Anand'. People asked me questions like, 'How is he to look at? What does he do?''

The mega story had a small beginning in Amritsar. Born Jatin Arora on December 29, 1942, he was adopted and raised by foster parents.

He went from being Jatin to Rajesh, thanks to his uncle who changed his name when he decided to join films.

In 1965, the journey to filmdom started after he won the All India Talent Contest organised by United Producers and Filmfare. He made his debut with Aakhri Khat in 1966.

Rajesh Khanna became the heartthrob of the nation, singing timeless melodies like Mere Sapnon Ki Rani... in Aradhana, Zindagi Ek Safar in Andaaz or Yeh Shaam Mastani in Kati Patang. Singer Kishore Kumar and composer R.D. Burman were amongst his closest friends.

In his four-decade career, Rajesh Khanna appeared in about 160 films, of which 106 had him as the solo lead hero and 22 were two hero projects.

Rajesh Khanna proved his mettle in offbeat films too. He teamed up with Hrishikesh Mukherjee for the critically acclaimed Bawarchi and Namak Haram.

The quintessential romantic actor also did the intense Avishkar, directed by Basu Bhattacharya.

But then age caught up and Rajesh Khanna's stardom began fading away.

He moved to television and played the main lead in two serials - Ittefaque and Apne Paraye during 2001-02 and also featured in Raghukul Reet Sada Chali Aayi between 2008-09.

The decline to B-grade films was inevitable. Rajesh Khanna also starred in Wafa with Laila Khan.

Rajesh Khanna dabbled in politics, being Congress MP from the New Delhi constituency from 1991-1996.

When Rajesh Khanna was a member of Parliament for the Indian National Congress he did not take up any film project, however, acted in the film Khudai (1994).

Talking about his personal life, like the Hollywood legends of yore, Rajesh Khanna's personal life also had a larger than life dimension.

He fell in love with Dimple Kapadia, who was only 16 and whose first film Bobby was yet to release.

Dimple Kapadia was 15 years younger to him but the pull was strong and they got married after a whirlwind romance in 1973. They had two daughters Twinkle and Rinke. The marriage lasted 11 years.

It was a lonely life for Rajesh after that. He disappeared from the headlines and appeared to be a shadow of his former self in his rare public appearances.

But the family came together in his last days. His estranged wife was the one who took care of him during his illness.

Son-in-law Akshay Kumar was also a great comfort.

Rajesh reappeared in an ad a few months before his death, and once again became the talk of the town - he was clearly unwell but the zest in his voice was intact as he intoned Babumoshai from his much-loved film Anand.

Here are some interesting trivia you probably didn't know about Rajesh Khanna:

Rajesh Khanna tried his hand at direction with Jai Shiv Shankar in 80s. His wife Dimple was paired opposite Kaka in the film, which never saw the light of the day.

During the filming of the song Mere Sapnon Ki Rani in Aradhana, Sharmila Tagore was shooting for a Satyajit Ray film. Hence, director Shakti Samanta had to shoot their scenes separately and then join the scenes together.

Rajesh Khanna's cheerful Punjabi character in Anand was based on actor-filmmaker Raj Kapoor, while his Bengali friend Bhaskar Banerjee (played by Amitabh Bachchan) was modelled on director Hrishikesh Mukherjee himself.

The superstar's debut was Aakhri Khat and it led to a spate of hits like Aaradhna, Amar Prem, Aan Milo Sajna, Aap Ki Kasam, Anurodh, Avtaar, all starting with A.

Jeetendra and Rajesh went to the same school in Girgaum and then later to KC College too. In fact, it was Khanna who inspired and supported Jeetendra to get into movies.

Rajesh Khanna was earlier slated to play the lead in Deewar.

Rajesh Khanna's uncle, who disapproved of his acting aspirations, asked him to change his real name from Jatin if he wanted to act.

You are truly being missed Kaka!
