The Advance of the Islamic Courts Union is the period in the Somali Civil War that began on May 2006 with the Islamic Courts Union's (ICU) conquest of Mogadishu from the Alliance for the Restoration of Peace and Counter-Terrorism (ARPCT) and continued with further ICU expansion in the country. Following the outbreak of the 2006 Somali War on December 21, 2006, by December 24, direct Ethiopian intervention in the conflict in support of the Transitional Federal Government (TFG) was no longer denied by the Ethiopian government. The Eritrean government denied any involvement despite Ethiopian claims to the contrary.
