Although Zhang Zuolin's Fengtian clique played a minor role assisting the Zhili clique in the war, they were allowed to share power in Beijing.
Jin Yunpeng, who had ties to both sides, was chosen as premier.
President Xu called for parliamentary elections in the summer of 1921 but because only 11 provinces took part the elections became invalid and no assembly was convened.

Zhang became worried over Wu Peifu's growing military strength and anti-Japanese stance which threatened his backers in Japan.
Using a financial crisis as a pretext, he removed Jin and replaced him with Liang Shiyi in December 1921.
Wu forced Liang to resign after a month accusing him of being pro-Japanese.
He exposed Liang's telegram ordering diplomats to back Japan on the Shandong Problem during the Washington Naval Conference.
Zhang then formed an alliance with the Duan Qirui and Sun Yatsen.
Both sides sent circular telegrams to rally their officers and denounce their enemies.
On April 28, the First Zhili–Fengtian War began with Wu clashed with Zhang's army in Shanhaiguan and won a major victory forcing Zhang to retreat to Manchuria.

Next, the Zhili clique started a national campaign to restore Li Yuanhong as president.
Despite having co-existed with Xu Shichang for two years after the fall of Duan, they declared his presidency illegal as he was elected by an illegal parliament.
They demanded Xu and Sun Yatsen resign their rival presidencies in favor of a unified government.
Wu convinced Chen Jiongming to oust Sun from Guangzhou in return for recognition of his control over Guangdong.
Enough members of the old parliament moved to Beijing to constitute a quorum which superficially gave the government an appearance that it operated as it did before the Manchu Restoration in 1917.

Li's new administration was more powerless than his first.
His cabinet appointments had to be approved by Wu Peifu.
Wu's growing power and prestige outshone his mentor and superior officer, Cao Kun, which strained relations between the two.
Cao wanted to become president himself but Wu tried to restrain his ambitions.
President Li tried to create an "Able Men Cabinet" consisting of experts but he ruined it by arresting Finance Minister Luo Wengan on spurious rumours supplied by the speakers of parliament.
The cabinet resigned en-masse and Wu was no longer able to shield Li.
Cao Kun's followers controlled the new cabinet and bribed parliament to impeach Li.
Next, Cao orchestrated strikes by unpaid police and had the utilities for the presidential manor cut.
Li tried to take the presidential seal with him but was intercepted.

Cao Kun spent the next few months promoting his presidency by openly offering five thousand dollars to any member of parliament willing to elect him.
This created universal condemnation but he was nevertheless elected and was inaugurated on Double Ten Day, 1923 with a new constitution, the only formal constitution promulgated until 1947.
He neglected his presidential duties and would rather meet with his officers than the cabinet.
The vice presidency was again left vacant to entice Zhang Zuolin, Duan Qirui, or Lu Yongxiang but none wanted to associate with Cao's infamy.

In September 1924, the Zhili clique general and Jiangsu governor Qi Xieyuan demanded control of Shanghai, which belongs in his province, from Lu Yongxiang's Zhejiang the last province controlled by the Anhui clique.
Fighting broke out between the two provinces with Qi quickly gaining ground.
Sun Yatsen and Zhang Zuolin pledged to protect Zhejiang, sparking the Second Zhili–Fengtian War.
Zhejiang fell and for the next two months Wu was gradually winning against Zhang.

In the early morning hours of October 23, General Feng Yuxiang betrayed the Zhili clique by pulling off the Beijing Coup.
He put President Cao under house arrest.
Wu reacted furiously at this betrayal by pulling his army from the front to rescue Cao.
Zhang pursued and attacked Wu's rear, defeating him at Tianjin.
Wu escaped to the Central Plains where Sun Chuanfang held the line against Zhang.
