Seventy-five years ago, Mohandas K. Gandhi was shot dead by an assassin while on his way to deliver a regular evening prayer. Gandhi, by then largely known as the mahatma, or “great soul,” had helped lead India into its independent future less than a year before, with millions of Indian nationalists by his side. He died as one of the most celebrated men on earth.

“The light has gone out of our lives,” Jawaharlal Nehru, the first prime minister of independent India, told the weeping masses by radio on Jan. 30, 1948, the day of the assassination.

In his famous, impromptu elegy, Nehru promised that the light brought by Gandhi would “illumine this country for many more years. And a thousand years later, that light will be seen in this country and the world will see it and it will give solace to innumerable hearts.”

Gandhi is still revered far and wide, his name a byword for a certain kind of virtue and action. Nearly every town in India’s countryside has a main street named “M.G. Road” in his honor, and some of the biggest government programs of the 21st century bear his name, too. But India has changed in innumerable ways since 1948, when his life was snuffed out by Nathuram Godse, a Hindu ideologue with a Beretta pistol.

Mr. Godse had murdered Gandhi as a political enemy, accusing him of being a traitor to Hindus. Mr. Godse was a Hindu nationalist, who loathed what he saw as Gandhi’s deference to minorities and resented the division of colonial India between an explicitly Muslim Pakistan and a multireligious, secular (though Hindu-majority) republic of India. Narendra Modi, the popular and increasingly powerful prime minister of the past eight years, has roots in the same Hindu nationalist movement. Members of his party have been caught celebrating Mr. Godse — and rebuked for it — but have then been allowed to stay in Parliament.

Mr. Modi praises Gandhi at ritually appropriate occasions, but there is relatively less veneration for Gandhi in India’s public spaces now.

Today’s India is much prouder of its industrial and military achievements than Gandhi might have liked, and it is eager for more. Mr. Modi’s messaging suits that mood better. Still, Gandhi’s commitments to an independent and self-sufficient India, his wit and steely resolve and his ability to mix aspects of spiritual leadership with political continue to command respect.

As India evolves and finds its stature ever greater on the world stage, The New York Times pored over archival photographs to look back at those years of light that Gandhi brought to his countrymen and to the world. Here is a selection.

In the first of these images, Gandhi, right, is pictured with his brother Laxmidas Gandhi in 1886 in India. In the second photograph, he is in the center, in South Africa, where he was practicing law.

Gandhi addressing a farewell gathering in South Africa in 1914 before going to Britain and later to India in 1915. It was around this time that the honorific “mahatma” or “great soul” was first applied to him.

Gandhi in 1924 with Indira, the daughter of Nehru, who was prime minister after India gained independence in 1947. She would later also serve as the country’s prime minister, known by her married name, Indira Gandhi. (She was not related to Mohandas K. Gandhi and was herself assassinated, in 1984.)

Gandhi in 1930 at the start of the protest that became known as the Salt March. Over several weeks, he and his followers walked some 240 miles from his religious retreat on the Sabarmati River in Gujarat to the coast at the town of Dandi, urging Indians to defy colonial laws taxing salt and restricting its production. The march ignited a major campaign of civil disobedience, and focused international attention on Gandhi and his advocacy of satyagraha, or nonviolent resistance.

Crowds gathered on London streets as Gandhi visited the East End, where he called attention to the area’s poor by forsaking a hotel and staying at a community house.

While in East London, Gandhi met with Charlie Chaplin, to his right. Chaplin wrote that it was the meeting with Gandhi that inspired him to make “Modern Times,” which depicted the dehumanizing effects of mass production.

Gandhi meeting with Lord Mountbatten, the new viceroy of India, and his wife, Lady Edwina Mountbatten, in 1947. It was the homestretch for colonial rule: India would be independent, and the viceroys no more, within the year.

Growing unrest between Hindus and Muslims exploded into riots before India’s independence in 1947, along with its partition into India and Pakistan, leading Jinnah and Gandhi to jointly appeal for peace.

After the assassination, Gandhi’s grandniece placed petals on his head as his body was lying in state at Birla House.

Gandhi was cremated on the banks of the Yamuna River.

Crowds lined the railway tracks to pay homage as some of Gandhi’s ashes were carried by train to the Ganges River to be scattered.
