Demonstrators gathered at the entrance to the office of Hong Kong’s chief executive, Leung Chun-ying, as well as occupying the streets outside the government’s headquarters

The students taking part in the occupation ended up in a stand-off with the authorities that lasted for months
The protest was initiated after a decision to allow Hong Kong to hold elections but only featuring candidates pre-approved by the mainland Chinese government

At one point, pro-democracy protesters opened their umbrellas for 87 seconds, marking the 87 rounds of teargas fired by the Hong Kong police at unarmed student protesters
