Chiranjeevi, who has acted in more than 150 films, is one of the most versatile actors with huge fan following across the country.

Chiranjeevi was born in Andhra Pradesh as Konidela Siva Sankara Vara Prasad in a middle-class family. After graduation in Narsapur, he joined the Madras Film Institute in 1976 to pursue a career in acting.

After the initial struggle in the industry, he worked his way to the top with his tremendous acting, impeccable dialogue delivery, brilliant comic timing and superb dancing skills.

After enjoying the massive popularity in Tollywood for over two decades, Chiranjeevi entered politics in 2008 by launching Praja Rajyam Party (PRP). However, he was unsuccessful as the party could win just 18 seats in the 294-member state Assembly of the then undivided Andhra Pradesh during 2009 elections.

Later, Chiranjeevi merged his party with the Congress and became a Union Minister during the UPA government led by Manmohan Singh. After 2014 elections, he became inactive in politics and returned to films in 2017 with the action-drama 'Khaidi No. 150'.

In 2019, Chiranjeevi acted in the period action fim 'Sye Raa Narasimha Reddy' based on the life of freedom fighter Uyyalawada Narasimha Reddy.
