Confidence votes 11. The new Republic of China fell into chaos after 1912 because of the mistakes of Yuan Shikai. In 1912, after Sun Yixian(AKA Sun Yat-Sen) stepped down as president in favor for him, Yuan Shikai tried to foolishly create another dynasty.However, the military didn't back him and opposition divided the nation.ventually, the KMT retreated o the island of Taiwan and the CPC became the People's Republic of China (PRC) in 1949. There was never a peace agreement between both nations so both governments claim to be the legitimate government of all of China.
By all accounts, Jimmy Carter was a tremendous failure as a president. The economy was bad, he failed to get the hostages out of Iran, he did nothing to stop the fuel crisis â¦ . All in all, he is considered one of the worst in history. However his history will not be forgotten for the good things..immy Carter has been said by MANY people to have been one of the worst presidents this country has ever had. He is definitely in the top 3. Many think so, in large part, due to failed economic & foreign policy debacles...and what has been perceived by many as an inflammatory anti-Jewish and anti-Israel stance.
