In 1845, the bishop of the American Episcopal Church, W. J. Boone, bought an area in Hongkew to create real estates in Shanghai to build a church. Later, Boone proposed to develop an American settlement, and in 1848, the Shanghai County approved the proposal. On 25 June 1863, American consul George Seward signed an agreement with the head of Shanghai County, Huang Fang (黃芳), to create the American Concession in Shanghai, which also confirmed the boundary of the area.[1] On 21 September 1863, the American area was merged with the British as the Shanghai International Settlement.
