"The 2018 Bhima Koregaon incident refers to violence that broke out following an annual celebratory gathering at Bhima Koregaon to mark the 200th year of the Battle of Bhima Koregaon.The gathering consisted largely of Dalits, and interference by upper caste Maratha groups on the Dalit gathering resulted in escalation of an already tense gathering into violence."
