This time last year, pro-democracy demonstrators held the heart of one of Asia’s great cities, the beginning of a months-long occupation that would shake Hong Kong and make headlines around the world.

In late September 2014, a group of demonstrators, led by student activist Joshua Wong, was arrested trying to occupy a public square and detained for 40 hours. Thousands took to the streets in anger, only to be sprayed with tear gas. And they defended themselves with what they had on hand — umbrellas.

The Umbrella Movement called for full democracy for the former British colony, asking Beijing to back away from plans to vet candidates for the city’s top job.

Beijing did not budge. A year later, the city’s downtown core is packed with taxis, not tents. Outside government headquarters, protesters have left notes and banners to mark the anniversary — a quiet reminder that, although the crowds have dispersed, the debate over Hong Kong’s future is far from finished.

At that moment, you saw a totally different aspect of Hong Kong people.” (Bobby Yip/Tyrone Siu/Reuters)
