The pent-up hopes and frustrations of India’s young people found a release in a protest movement that gathered steam this past week in the capital, New Delhi.

A crowd of thousands was mobilized by a call by the leaders of a youth movement to reform India’s troubled education system and to push for the resignation of the country’s education minister, blamed for botching a college-entrance exam that left millions in the lurch.

After a violent crackdown by police on Monday, the anger remained and the spirit of the protests appeared to have become more inclusive, attracting activists and academics, curious teenagers, blue-collar parents and children from affluent homes, established celebrities and newly minted influencers, atheists, farmers, religious leaders, and even a man wearing a Spiderman mask.

The movement is posing one of the most substantial challenges in years to the leadership of India’s prime minister, Narendra Modi. The anger is hard for him to ignore, with young people accounting for 40 percent of India’s population.

Here are some of their voices:

AMAL HAYAT, 20

Amal Hayat, 20, a student of electrical and computer engineering at Delhi’s Jamia Millia Islamia University, is the kind of young person whose ambitions are essential to Mr. Modi’s vision of a “Vikshit Bharat,” or developed India, by 2047.
