For years the Arab League has been seen as a cosy club of Arab autocrats and dictators.
Ministerial meeting followed summit followed emergency summit, all having no apparent impact on the lives of ordinary Arabs in this troubled region.
But the Arab League headquarters are barely a couple of hundred metres from Tahrir Square, in central Cairo.
And the effect of the protests there, which unseated former Egyptian President Hosni Mubarak, are still echoing round the marbled halls of the League.
In March the League voted in support of a no-fly zone over Libya. The move led directly to a UN resolution and subsequent Nato intervention. Without the Arab League vote, that would not have been possible.
Now in an almost equally dramatic step, the League has voted to suspend Syria from its work in response to the continuing violence in the country.
That means one of the standard-bearers of Arab nationalism, the Syrian Arab Republic, is now excluded from the body committed to Arab unity.
Members of the Syrian opposition - just the sort of activists whom the Arab League members happily ignored or repressed for years - are being invited to Arab League headquarters, for the League to help them co-ordinate their efforts.
All of this is being pushed forward not by the traditional Arab leader, Egypt, but by tiny Qatar, whose prime minister is chairman of the ministerial committee dealing with Syria.
The hard line towards Syria emanating from the Qatari capital, Doha, is almost equalled by the tough stand from neighbouring Saudi Arabia.
The diplomatic map of the Middle East is being redrawn almost as quickly as governments and regimes are falling.
Syria's immediate response has been to attack the League as a tool of the US.
That is an ironic charge indeed against a body that has been so hostile for so long to America's biggest ally in the region, the state of Israel.
In fact a more complicated dynamic is being played out.
