How umbrellas became the symbol of the Hong Kong protests

Hong Kong's protestors have been using umbrellas to block tear gas, a practice that's becoming so ubiquitous that people have even started dubbed the protests the "Umbrella Revolution."

But this all started with weather — specifically, rain and sun.

So there are a lot of umbrellas floating around in late September in Hong Kong. But during the current round of protests, it happened to be unusually hot and sunny. According to the BBC, demonstrators originally brought their spare umbrellas to block out sunrays. That meant that when the police began spraying tear gas at protesters, they had a handy implement to block the toxic stuff.

The utilitarian adaptation quickly turned into an instantly recognizable symbol for the protest movement. "It's a wonderful symbol, I think, which seems to have emerged organically from [umbrellas] being used to block pepper spray and then tear gas," Jeff Wasserstrom, a UC-Irvine professor who studies protest in China, wrote via email.

Umbrellas have also become part of protest strategy. "The police have been using pepper spray quite liberally in their attempts to contain protests," Ho-Fung Hung, a sociologist of China at Johns Hopkins, told Quartz.  "The protestors are organized, they're very prepared. So you see this ocean of umbrellas on the front line."

The striking visual image of one man holding an umbrella amidst gas clouds is quickly becoming the iconic photograph from the Hong Kong protests. Dubbed "Umbrella Man," after the famous "Tank Man" who was photographed standing in front of Chinese army tanks during the 1989 Tiananmen protests, this unidentified protester is now a highlight of social media commentary on the protests.

Some protesters, according to the Washington Post's Adam Taylor, have even used umbrellas as impromptu billboards, scrawling messages on the top.

Whoever thought umbrellas could become so important?

Correction: An earlier version of this post misstated the approximate number of rainy days in Hong Kong in July and September. That's been corrected.

Will you support Vox’s explanatory journalism?

Most news outlets make their money through advertising or subscriptions. But when it comes to what we’re trying to do at Vox, there are a couple reasons that we can't rely only on ads and subscriptions to keep the lights on.

First, advertising dollars go up and down with the economy. We often only know a few months out what our advertising revenue will be, which makes it hard to plan ahead.

Second, we’re not in the subscriptions business. Vox is here to help everyone understand the complex issues shaping the world — not just the people who can afford to pay for a subscription. We believe that’s an important part of building a more equal society. We can’t do that if we have a paywall.

That’s why we also turn to you, our readers, to help us keep Vox free. If you also believe that everyone deserves access to trusted high-quality information, will you make a gift to Vox today?
