An extract from Wikipedia gives the following brief history:
The Tsinghua College (清華學堂 Qīnghuá Xuétáng) was established in Beijing, China, on 22 April 1911 on the site of a former royal garden belonging to a prince. It was funded by the Boxer Rebellion Indemnity Scholarship Program, which consisted of unexpected surplus money from indemnities China had paid the United States following the Boxer Rebellion. It was first a preparatory school for students later sent by the government to study in the United States. The faculty members for sciences were recruited by the YMCA from the United States and its graduates transferred directly to American schools as juniors upon graduation. In 1925, the school established its College Department and started its research institute on Chinese Study.
In 1928, the authority officially changed its name to National Tsing Hua University (NTHU). During the Second World War in 1937, Tsinghua University along with Peking University and Nankai University, merged to form Changsha Temporary University in Changsha, and later National Southwestern Associated University in Kunming of Yunnan province. After the war, Tsinghua moved back to Beijing and resumed its operation.
