In 1906, the Tongmenghui, a revolutionary group led by Sun Yat-Sen aiming to overthrow the Qing dynasty, established its Southeast Asian headquarters in Singapore. This organization played a significant role in events like the Xinhai Revolution, leading to the founding of the Republic of China. The immigrant Chinese community in Singapore financially supported such revolutionary groups, which would later become the Kuomintang. The historical significance of this movement is commemorated in Singapore's Sun Yat Sen Nanyang Memorial Hall, formerly known as the Sun Yat Sen Villa. Notably, the flag of the Kuomintang, which became the flag of the Republic of China, was crafted in this villa by Teo Eng Hock and his wife.
