The Umbrella Movement, also known as the Umbrella Revolution, was a pro-democracy protest movement in Hong Kong that took place from September 26 to December 15, 2014, lasting 79 days. It emerged as a response to Beijing's restrictive electoral reforms and became one of the largest civil disobedience campaigns in Hong Kong's history since its handover to China in 1997. The movement's iconic name derives from protesters using umbrellas to shield themselves from police tear gas and pepper spray, symbolizing peaceful resistance.
