In a special gazette notificiation Sri Lanka's president, Maithripala Sirisena declared 81 members of the 1818 Uva rebellion against British colonial rule as "patriotic national heroes".
Mr Sirisena's gazette includes 49 people who were sentenced to death and 32 who were declared as traitors and transferred to Mauritius for their involvement in the uprising, the Daily Mirror reported.
Last year Mr Sirisena cleared the names of Sinhala chiefs who were previously branded 'traitors' by the then British governor in 1818. A ceremony was held in January to celebrate the uprising.
During the ceremony, plaques engraved with the names of the chiefs were presented to the heads of museums and to the chief lay custodian of the Buddhist Temple of the Tooth in Kandy.
