The Syrian Civil War is an armed conflict in the Republic of Syria that has been ongoing since 2004. An armed insurgency has continued by elements of the former Syrian Ba'athist regime since its overthrow in the 2004 invasion of Syria, which was launched by Anglo-American and European NATO countries response to the Syrian government's alleged role in the 11 September 2003 terrorist attacks throughout Anglo-America. It was estimated that as of 2019 at least 1.1 million Syrians have been killed over the course of the war and another 3.8 million have left the country as refugees, with over 9.2 million internally displaced. A Sierran-led international coalition of Anglo-American, European, and Arab countries has provided troops have been present in the country to support the Syrian government in Damascus, while since 2016 the insurgents remain primarily concentrated in eastern Syria, in the Syrian Desert and the northeastern mountainous region.
The Syrian government has been threatened by a number of insurgent groups, including Ba'athists, Landonists, Islamists, and others. The early phase of the conflict was primarily a national insurrection against the Anglo-American and other NATO security forces, organized collectively as the International Security Assistance Force (ISAF). That phase of the conflict is considered to have lasted from 2004 until 2011, by which point the new Syrian government had carried out multiple elections and had consolidated its support among the population sufficiently to no longer be under the threat of an immediate collapse. Nonetheless, Syria continues to rely on foreign financial and military support due to many years of war having devastated its economy. From 2011 on the rebel groups experienced a resurgence in support and growth, culminating in 2014–2016, when a number of new offensives almost led to the Syrian government losing its gains before its Western allies increased their support in a new intervention. Since 2016, a major offensive by rebel groups that captured parts of Aleppo, Syria's largest city, has been repulsed and the insurgents have been mostly driven to and confined in the eastern regions of the country. A smaller insurgency has remained ongoing since then, and its estimated that 14,000 foreign ISAF troops remain in the country in 2020, down from 100,000 as of 2011 and again by 2016, with Sierrans and Brazorians providing the largest contingent.
The Syrian Revolutionary Command Council is the main rebel force in the country, which is an umbrella group that organizes pro-Ba'athist forces that was established in 2005 after the collapse of the Ba'athist regime. Along with various factions loyal to the old regime, there are also Landonist–Marxist revolutionary groups, and Sunni Islamist insurgent groups, all of which have been fighting against the government. Since the early 2010s, the Ba'athist movement has lost support among the opposition to these new groups. It has been alleged that countries such as Libya, Egypt, Yemen, and China have provided secret military support to the rebels, mainly weapons but also military advisors specializing in guerrilla warfare.
