A student-led protest in Hong Kong, with umbrellas, had its beginnings 10 years ago. It quickly grew and at times, brought parts of the city to a standstill, also becoming a global symbol for peaceful resistance. Several of the movement's leaders were later convicted of public nuisance charges and sentenced to jail. While it has been described as a watershed moment for the pro-democracy movement in China's special administrative region, freedoms in Hong Kong have since further eroded. According to estimates by the Hong Kong Democracy Council, there are currently more than 1,800 political prisoners in Hong Kong.
