49 years ago today General Abd al-Karim Qasim was overthrown in a Ba’ath party coup. Four months later, the flag that was associated with his regime was replaced by the red-white-and black tricolor which forms the basis of the modern Iraqi flag.
In recent years, Qasim’s flag has enjoyed something of a resurgence in Kurdistan, where the current Iraqi flag is closely associated with the oppression of Saddam Hussein's regime. It probably helps that the old flag prominently features a golden sun representing the Kurdish people. One of the 2008 proposals for a new Iraqi flag would have added this sun to the centre of the current tricolour.
