Old Guangxi clique New Guangxi clique Guangdong warlords Sichuan clique Hunan warlords North The death of Yuan Shikai split the Beiyang Army into two main factions. The Zhili and Fengtian clique were in alliance with one another, while the Anhui clique formed their own faction. International recognition was based on the presence in Beijing, and every Beiyang clique tried to assert their dominance over the capital to claim legitimacy. Duan Qirui and Anhui dominance (1916–1920) While Li Yuanhong replaced Yuan Shikai as the President after his death, the political power was in the hands of Premier Duan Qirui. The government worked closely with the Zhili clique, led by Vice President Feng Guozhang, to maintain stability in the capital. Continuing military influence over the Beiyang government led to provinces around the country refusing to declare their allegiance. The debate between the President and the Premier on whether or not China should participate in the First World War was followed by political unrest in Beijing. Both Li and Duan asked Beiyang general Zhang Xun, stationed in Anhui, to militarily intervene in Beijing. As Zhang marched into Beijing on 1 July, he quickly dissolved the parliament and proclaimed a Manchu Restoration. The new government quickly fell to Duan after he returned to Beijing with reinforcements from Tianjin. As another government formed in Beijing, Duan's fundamental disagreements over national issues with the new President Feng Guozhang led to Duan's resignation in 1918. The Zhili clique forged an alliance with the Fengtian clique, led by Zhang Zuolin, and defeated Duan in the critical Zhili–Anhui War in July 1920. Cao Kun and Zhili dominance (1920–1924) After the death of Feng Guozhang in 1919, the Zhili clique was led by Cao Kun. The alliance with the Fengtian was only one of convenience and war broke out in 1922 (the First Zhili–Fengtian War), with Zhili driving Fengtian forces back to Manchuria. Next, they wanted to bolster their legitimacy and reunify the country by returning Li Yuanhong to the presidency and restoring the National Assembly. They proposed that Xu Shichang and Sun Yat-sen resign their rival presidencies simultaneously in favour of Li. When Sun issued strict stipulations that the Zhili could not stomach, they caused the defection of KMT Gen. Chen Jiongming by recognizing him as governor of Guangdong. With Sun driven out of Guangzhou, the Zhili clique superficially restored the constitutional government that existed prior to Zhang Xun's
