Bloody Thursday (Arabic: ) is the name given by Bahraini protesters to 17 February 2011, the fourth day of the Bahraini uprising as part of the Arab Spring. Bahraini security forces launched a pre-dawn raid to clear Pearl Roundabout in Manama of the protesters camped there, most of whom were at the time asleep in tents; four were killed and about 300 injured. The event led some to demand even more political reform than they had been before, calling for an end to the reign of King Hamad bin Isa Al Khalifa.

The clearance was described by witnesses as being brutal and sudden. Clouds of tear gas covered the area, and volleys of birdshot were fired on those who refused to withdraw. Medics, ambulances and a journalist were reportedly attacked as well. Sporadic clashes broke out around Bahrain hours after the raid. During the afternoon the National Guard and army deployed armoured vehicles, tanks, more than 50 armoured personnel carriers and set up checkpoints in the streets around the country. Protesters then took refuge at Salmaniya Medical Complex and continued their agitations; thousands of them chanted "Down with the king, down with the government."

The Bahraini government accused protesters of attacking the security forces, 50 of whom sustained injuries, and insisted that action had been necessary to pull Bahrain back from the "brink of a sectarian abyss". But opposition parties dismissed the government's account as a "silly play", described the raid as a "heinous massacre" and submitted their resignations from the lower house of Parliament.

Internationally, the Gulf Cooperation Council Ministers of Foreign Affairs expressed their solidarity with government of Bahrain and their support for the measures taken. The United Nations, the European Union and the United States on the other hand expressed their deep concern and regret for the violence used against protesters. The United Kingdom government announced that in light of the unrest it would revoke some arms export licences to Bahrain. A number of international rights groups and independent observers criticised the government crackdown.

The First Libyan Civil War was an armed conflict in 2011 in the North African country of Libya which was fought between forces which were loyal to Colonel Muammar Gaddafi and rebel groups that were seeking to oust his government. It erupted with the Libyan Revolution, also known as the 17 February Revolution. The war was preceded by protests in Zawiya on 8 August 2009 and finally ignited by protests in Benghazi beginning on Tuesday, 15 February 2011, which led to clashes with security forces that fired on the crowd. The protests escalated into a rebellion that spread across the country, with the forces opposing Gaddafi establishing an interim governing body, the National Transitional Council.

The United Nations Security Council passed an initial resolution on 26 February, freezing the assets of Gaddafi and his inner circle and restricting their travel, and referred the matter to the International Criminal Court for investigation. In early March, Gaddafi's forces rallied, pushed eastwards and re-took several coastal cities before reaching Benghazi. A further UN resolution authorised member states to establish and enforce a no-fly zone over Libya, and to use "all necessary measures" to prevent attacks on civilians, which turned into a bombing campaign by the forces of NATO against Libyan military installations and vehicles. The Gaddafi government then announced a ceasefire, but fighting and bombing continued. Throughout the conflict, rebels rejected government offers of a ceasefire and efforts by the African Union to end the fighting because the plans set forth did not include the removal of Gaddafi.In August, rebel forces launched an offensive on the government-held coast of Libya, backed by a wide-reaching NATO bombing campaign, taking back territory lost months before and ultimately capturing the capital city of Tripoli, while Gaddafi evaded capture and loyalists engaged in a rearguard campaign. On 16 September 2011, the National Transitional Council was recognised by the United Nations as the legal representative of Libya, replacing the Gaddafi government. Muammar Gaddafi evaded capture until 20 October 2011, when he was captured and killed in Sirte. The National Transitional Council declared "the liberation of Libya" and the official end of the war on 23 October 2011.In the aftermath of the civil war, a low-level insurgency by former Gaddafi loyalists continued. There have been various disagreements and strife between local militia and tribes, including fighting on 23 January 2012 in the former Gaddafi stronghold of Bani Walid, leading to an alternative town council being established and later recognized by the National Transitional Council (NTC). A much greater issue has been the role of militias which fought in the civil war and their role in the new Libya. Some have refused to disarm, and cooperation with the NTC has been strained, leading to demonstrations against militias and government action to disband such groups or integrate them into the Libyan military. These unresolved issues led directly to a second civil war in Libya.
