Thousands of working-class families lined the streets of London’s East End neighborhood on March 24 to honor the passing of Britain’s most militant labor leader of his generation: Bob Crow, who died suddenly at age 52 after a suspected heart attack on March 11. For a dozen years, Crow headed the Rail, Maritime and Transport Union (RMT), where he led many strikes and made no apologies for being an avowed socialist and fighter for the working class.

Like the ILWU, the RMT and Bob Crow celebrated the power of solidarity at home and abroad. He regularly attended ILWU events, including the 2012 Convention in San Diego. International Vice President (Mainland) Ray Familathe attended the funeral on behalf of the ILWU.

“Bob brought so much passion and intelligence to every fight,” said Familathe. “There haven’t been many like him with his talent and commitment, which is why his loss is so stunning and sad.”

The hour-long procession from the East End to City of London Cemetery was observed by local union members, pensioners and supporters from around the world who clapped as the horse-drawn hearse carrying Crow’s casket passed, moving some to throw roses and shed tears while others sang socialist songs.

Alfonso Bahena, from Rio de Janeiro in Brazil, said Mr. Crow’s legacy went far beyond Britain. “Bob Crow spoke at our Congress in Mexico City in 2010 and he was one of the most important people,” said Bahena who represented the International Transport Workers’ Federation (ITF). “He helped make a lot of policy for the railway workers in Brazil and South America.”

Crow’s loyalty extended to other groups in England that found him willing to support their causes, including coal miners, pensioners, and activists at the Campaign for Nuclear Disarmament.

As the leader of the RMT, he headed many strikes including a recent walk-out by London Underground workers. His tough stance frequently provoked controversy and drew sharp criticism from politicians who resented Crow’s loyalty among workers.

Crow was a passionate supporter of the Millwall Football Club, a working-class team founded in London’s East End near the docks, with a slogan fitting for Crow as well: “No one likes us – and we don’t care.”

“Some politicians called him the most hated man in Britain,” said one woman waiting for the procession.

“But today it looks like he was the most loved.” A memorial honoring Crow’s life and values is slated for London’s May Day celebration.
