Civil disorder

This list of Roman civil wars and revolts includes civil wars and organized civil disorder, revolts, and rebellions in ancient Rome (Roman Kingdom, Roman Republic, and Roman Empire) until the fall of the Western Roman Empire (753 BC – AD 476). For the Eastern Roman Empire or Byzantine Empire after the division of the Empire in West and East, see List of Byzantine revolts and civil wars (AD 330–1453). For external conflicts, see List of Roman external wars and battles.

From the establishment of the Roman Republic in 509 BC until the 1st century BC, there were a sparse number of civil wars. But with the Crisis of the Roman Republic (134–44 BC), a period of considerable political instability began. The cause of the late Roman Republican civil wars is contested, as is whether the wars were the cause of, or caused by, the end of the Roman Republic. Regardless, a nearly constant stream of civil wars marked the end of the Roman Republic and heralded the rise of the Roman Empire in 27 BC. The first century of Empire was marked by widespread revolt through territory Rome had captured in the preceding centuries. The second century AD was relatively peaceful, with a limited number of revolts. Political instability returned to the Empire with the Crisis of the Third Century (235–284 AD), which saw at least 26 civil wars in just 50 years as usurpers sought the imperial throne. The fourth and fifth centuries AD were characterized by a regular rising of usurpers. The overthrow of the last Western Roman emperor in AD 476 by the Germanic king Odoacer marked the final civil war or revolt, as well as the end of the Western Roman Empire.

The police are a constituted body of people empowered by a state with the aim of enforcing the law and protecting the public order as well as the public itself. This commonly includes ensuring the safety, health, and possessions of citizens, and to prevent crime and civil disorder. Their lawful powers encompass arrest and the use of force legitimized by the state via the monopoly on violence. The term is most commonly associated with the police forces of a sovereign state that are authorized to exercise the police power of that state within a defined legal or territorial area of responsibility. Police forces are often defined as being separate from the military and other organizations involved in the defense of the state against foreign aggressors; however, gendarmerie are military units charged with civil policing. Police forces are usually public sector services, funded through taxes.

Law enforcement is only part of policing activity. Policing has included an array of activities in different situations, but the predominant ones are concerned with the preservation of order. In some societies, in the late 18th and early 19th centuries, these developed within the context of maintaining the class system and the protection of private property. Police forces have become ubiquitous and a necessity in complex modern societies. However, their role can sometimes be controversial, as they may be involved to varying degrees in corruption, brutality, and the enforcement of authoritarian rule.

The Romanian revolution (Romanian: Revoluția română) was a period of violent civil unrest in Romania during December 1989 as a part of the revolutions of 1989 that occurred in several countries around the world, primarily within the Eastern Bloc. The Romanian revolution started in the city of Timișoara and soon spread throughout the country, ultimately culminating in the drumhead trial and execution of longtime Romanian Communist Party (PCR) General Secretary Nicolae Ceaușescu and his wife Elena, and the end of 42 years of Communist rule in Romania. It was also the last removal of a Marxist–Leninist government in a Warsaw Pact country during the events of 1989, and the only one that violently overthrew a country's leadership and executed its leader; according to estimates, over one thousand people died and thousands more were injured.

Following World War II, Romania found itself inside the Soviet sphere of influence, with Communist rule officially declared in 1947. In April 1964, when Romania published a general policy paper worked out under Gheorghe Gheorghiu-Dej's instructions, the country was well on its way of carefully breaking away from Soviet control. Nicolae Ceaușescu became the country's leader the following year. Under his rule, Romania experienced a brief waning of internal repression that led to a positive image both at home and in the West. However, repression again intensified by the 1970s. Amid tensions in the late 1980s, early protests occurred in the city of Timișoara in mid-December on the part of the Hungarian minority in response to an attempt by the government to evict Hungarian Reformed Church pastor László Tőkés. In response, Romanians sought the deposition of Ceaușescu and a change in government in light of similar recent events in neighbouring nations. The country's ubiquitous secret police force, the Securitate, which was both one of the largest in the Eastern Bloc and for decades had been the main suppressor of popular dissent, frequently and violently quashing political disagreement, ultimately proved incapable of stopping the looming, and then highly fatal and successful revolt.

Anarchy is a form of society without rulers. As a type of stateless society, it is commonly contrasted with states, which are centralized polities that claim a monopoly on violence over a permanent territory. Beyond a lack of government, it can more precisely refer to societies that lack any form of authority or hierarchy. While viewed positively by anarchists, the primary advocates of anarchy, it is viewed negatively by advocates of statism, who see it in terms of social disorder.

The word "anarchy" was first defined by Ancient Greek philosophy, which understood it to be a corrupted form of direct democracy, where a majority of people exclusively pursue their own interests. This use of the word made its way into Latin during the Middle Ages, before the concepts of anarchy and democracy were disconnected from each other in the wake of the Atlantic Revolutions. During the Age of Enlightenment, philosophers began to look at anarchy in terms of the "state of nature", a thought experiment used to justify various forms of hierarchical government. By the late 18th century, some philosophers began to speak in defence of anarchy, seeing it as a preferable alternative to existing forms of tyranny. This lay the foundations for the development of anarchism, which advocates for the creation of anarchy through decentralisation and federalism.

From October of 1965 to March of 1966, a series of large-scale killings and civil unrest primarily targeting members and supposed sympathizers of the Communist Party of Indonesia (PKI) were carried out in Indonesia. Other affected groups included alleged communist sympathisers, Gerwani women, trade unionists, ethnic Javanese Abangan, ethnic Chinese, atheists, accused "kafir" (unbelievers in Islam), and alleged leftists in general. According to the most widely published estimates, at least 500,000 to 1 million people were killed. Some of the higher estimates reach figures as much as 2 to 3 million. The atrocities, sometimes described as a genocide or a politicide, were instigated by the Indonesian Army under Suharto. Research and declassified documents demonstrate the Indonesian authorities received support from foreign countries such as the United States and the United Kingdom.

The killings began as an anti-communist purge following a so-called attempted coup d'état by the 30 September Movement. It was a pivotal event in the transition to the "New Order" and the elimination of PKI as a political force, with impacts on the global Cold War. The Army, after banning all independent news source from issuing for a week, almost at once pinned the abortive coup attempt to the PKI. Additionally, the intelligence agencies of the United States, United Kingdom and Australia engaged in black propaganda campaigns against Indonesian communists. During the Cold War, the U.S., its government, and its Western allies had the goal of halting the spread of communism and bringing countries into the sphere of Western Bloc influence. Britain had additional reasons for seeking Sukarno's removal, as his government was involved in an undeclared war with neighbouring Malaysia, a Commonwealth federation of former British colonies.

A riot or mob violence is a form of civil disorder commonly characterized by a group lashing out in a violent public disturbance against authority, property, or people.

Riots typically involve destruction of property, public or private. The property targeted varies depending on the riot and the inclinations of those involved. Targets can include shops, cars, restaurants, state-owned institutions, and religious buildings.
