A year ago, Hong Kong was in
the throes of political crisis, with riot police and anti-government protesters facing off in the streets amid calls for greater democracy. These days, the streets are mostly clear; protest art and slogans have been scrubbed off walls; politically sensitive books have been removed from library shelves; and now, the city is
about to lose almost all of its opposition in government. On Wednesday, the Beijing government passed a resolution allowing Hong Kong authorities to expel locally elected lawmakers, without having to go through the courts.
Immediately afterwards, four elected pro-democracy lawmakers were ousted from the city's legislature -- prompting the entire pan-democrat opposition bloc to announce their intention to resign in protest. The development marks the latest, perhaps fatal, blow to Hong Kong's embattled pro-democracy movement in a year that has seen authorities crack down on political dissent, arresting campaigners, activists and politicians. Here's what you need to know about the legislature turmoil, and how we arrived at this point.
