A series of sit-in street protests, often called the Umbrella Revolution and sometimes used interchangeably with Umbrella Movement, or Occupy Movement, occurred in Hong Kong from 26 September to 15 December 2014. The protests began after the Standing Committee of the National People's Congress (NPCSC) issued a decision regarding proposed reforms to the Hong Kong electoral system. The decision was widely seen to be highly restrictive, and tantamount to the Chinese Communist Party (CCP)'s pre-screening of the candidates for the Chief Executive of Hong Kong.
