Bharatiya Janata Party President Amit Shah remembered all the leaders, who dedicated their entire lives for the party that was established in 1980.

Greeting party workers, Modi tweeted: "39 years ago on this day, BJP was born with an unwavering commitment to serve society and take the nation to new heights. Thanks to the efforts of our karyakartas (workers), BJP has become India's preferred party."

The saffron party has always remained connected to the ground, and at the forefront when it came to helping fellow Indians, he added.

"The BJP stands tall due to it's democratic ethos and patriotic zeal. Our development work has endeared the party to all sections of society, across the length and breadth of India.

"I am confident that the entire family of BJP karyakartas would be working day and night to ensure that our party and our allies are blessed yet again by the people of India.

"In the last five years lots have been done and we want to do much more for the country," he added.

Shah, on the other hand, said that the BJP is an organisation having uncounted people without any family.

"They consider the party as their family... The journey of party's progress and political splendour has been possible because of the dedication of these members," Shah tweeted in Hindi.

He also urged the party workers to toil tirelessly to create a new India under Modi's leadership.
