China's 1911 revolution started 100 years ago today. It would go on to overthrow the Qing dynasty and 2,000 years of imperial rule.
The historic event is also known as the Xinhai revolution.
October 10 was celebrated as National Day on the mainland until the victory of communism in 1949. The day continues to be celebrated in Taiwan.
Several organisations in Hong Kong are commemorating the event with special shows.
They include exhibitions at the Dr Sun Yat-sen Museum and the Hong Kong Cultural Centre as well as an opera about Sun at the Hong Kong Cultural Centre.
The revolution was triggered on October 10, 1911, when a mutiny broke out in Wuchang , the capital of Hubei province.
Rebels fanned out across the country to gain support. By November, 14 out of 24 provinces had stood up against the Qing leadership, often violently.
Military leader Yuan Shikai was named premier, yet he could not suppress the rebellion.
In January, 1912, Sun returned from exile in the US.
He formed a new republic based on his 'Three Principles of the People' - nationalism, democracy and socialism - and was named provisional president. The new republic would continue to be mired in confusion and political division.
