The landing and reports of the violence had a large impact on many parties. The landing helped bring together the various groups of Turkish resistance into an organized movement (further assisted by the landing of Mustafa Kemal in Samsun on 19 May 1919). Several demonstrations were held by Turkish people in Constantinople condemning the occupation of Smyrna. Between 100,000 and 150,000 people gathered in a meeting at Sultanahmet square organized by the Karakol society and Türk Ocağı. In Great Britain and France, the reports of violence increased opposition in the governments to a permanent Greek control over the area.
