Following the withdrawal of US troops in 2011, the insurgency continued and Iraq suffered from political instability. In February 2011, the Arab Spring protests spread to Iraq; but the initial protests did not topple the government. The Iraqi National Movement, reportedly representing the majority of Iraqi Sunnis, boycotted Parliament for several weeks in late 2011 and early 2012, claiming that the Shiite-dominated government was striving to sideline Sunnis.
