(CNN)Security forces were out in full force in India's financial capital Mumbai this week, as members of the country's low-caste Dalit community demonstrated against alleged violence by right-wing Hindus.
Caste violence erupts in India over 200-year-old faultline
The unrest was concentrated in suburban areas on the outskirts of India's largest city, which also saw transport disruptions.
There were also sporadic protests across the state of Maharashtra, which Mumbai is located in.
It all began when tens of thousands of Dalits, who rank at the bottom of India's ancient Hindu caste hierarchy, gathered in the village of Bhima Koregaon, 170 kilometers (105 miles) outside of Mumbai, on New Year's day to celebrate the 200th anniversary of a battle in which British colonial forces staffed with local Dalit fighters defeated a numerically superior army belonging to upper caste rulers of the region.

Further, the anniversary of the battle at Bhima Koregaon is a historical moment of triumph for Dalits against people who they viewed as oppressors. Although the battle was fought for the British, it had a dual significance for the Dalit soldiers.

In Hinduism's caste system, Dalits are traditionally at the bottom rung. Members of the higher caste sometimes consider them impure, and in certain places, they still aren't allowed to enter the homes or temples of the upper-caste community or share utensils with them.
This practice, despite being unconstitutional, is still prevalent in parts of India, and Dalits continue t
