who initiated the construction of the grand canal
Grand Canal (China) In the late Spring and Autumn period (770–476 BC), Fuchai, King of the State of Wu (whose capital was in present-day Suzhou), ventured north to attack the State of Qi. He ordered a canal be constructed for trading purposes, as well as a means to ship ample supplies north in case his forces should engage the northern states of Song and Lu.[6] This canal became known as the Han Gou (邗沟, "Han Conduit").[7] Work began in 486 BC, from south of Yangzhou to north of Huai'an in Jiangsu, and within three years the Han Gou had connected the Yangtze with the Huai River by means of existing waterways, lakes, and marshes.[6]
History of the Panama Canal On October 10, 1913, the dike at Gamboa which had kept the Culebra Cut isolated from Gatun Lake was demolished; the detonation was made telegraphically by President Woodrow Wilson in Washington. On January 7, 1914, the Alexandre La Valley, an old French crane boat, became the first ship to make a complete transit of the Panama Canal under its own steam after working its way across during the final stages of construction.
