What was the boxer rebellion? what effect did it have on china?

The Boxer Rebellion was an anti-foreign, anti-christian, and anti-colonial violent uprising that took place in China from 1899 and 1901 in the Qing Dynasty. It was caused due to drought and disruption caused by the European spheres of influence and their growth. The movement was aided by the Empress Dowager Cixi, and her Imperial Army sieged christian places of worship, the Legation Quarter, foreign civilians and diplomats. In response the Eight Nation Alliance was formed (Empire of Japan, Russian Empire, British Empire, French Third Republic, the United States, the German Empire, the Kingdom of Italy, and the Austro-Hungarian Empire. They invaded and seized Beijing, and put an end to the events occurring (as well as executed anyone affiliated with the revolution, and sacked the city). The effects were that foreigners now saw that to control China, they needed to do so in a way that is indirect, non-territorial. Therefore political relations were reinforced, and ill will and sentiment went both ways to the foreigners and to the extremists. Especially now China has a rather ill view of foreigners meddling in their affairs, politically and militarily.
