Arab SpringThe Arab Spring (ar-rabīʻ al-ʻarabī) was a series of anti-government protests, uprisings and armed rebellions that spread across much of the Arab world in the early 2010s. It began in Tunisia in response to corruption and economic stagnation. From Tunisia, the protests then spread to five other countries: Libya, Egypt, Yemen, Syria and Bahrain. Rulers were deposed (Zine El Abidine Ben Ali of Tunisia in 2011, Muammar Gaddafi of Libya in 2011, Hosni Mubarak of Egypt in 2011, and Ali Abdullah Saleh of Yemen in 2012) or major uprisings and social violence occurred including riots, civil wars, or insurgencies.
RevolutionIn political science, a revolution (revolutio, 'a turn around') is an attempt to achieve fundamental and relatively sudden change in political power and political organization. It typically involves a revolt against the government due to perceived oppression (political, social, economic) or political incompetence. Revolutions have occurred throughout human history and vary widely in terms of methods, success or failure, duration, and motivating ideology.
Revolutions of 1848The Revolutions of 1848, known in some countries as the Springtime of the Peoples or the Springtime of Nations, were a series of revolutions throughout Europe over the course of more than one year, from 1848 to 1849. It remains the most widespread revolutionary wave in European history to date. The revolutions were essentially democratic and liberal in nature, with the aim of removing the old monarchical structures and creating independent nation-states, as envisioned by romantic nationalism.
Middle EastThe Middle East (term originally coined in English ) is a geopolitical region encompassing the Arabian Peninsula, the Levant, Turkey, Egypt, Iran, and Iraq. The term came into widespread usage as a replacement of the term Near East (as opposed to the Far East) beginning in the early 20th century. The term "Middle East" has led to some confusion over its changing definitions, and being seen as too Eurocentric.
Revolutions of 1830The Revolutions of 1830 were a revolutionary wave in Europe which took place in 1830. It included two "romantic nationalist" revolutions, the Belgian Revolution in the United Kingdom of the Netherlands and the July Revolution in France along with rebellions in Congress Poland, Italian states, Portugal and Switzerland. It was followed eighteen years later, by another and much stronger wave of revolutions known as the Revolutions of 1848.

SyriaSyria, officially the Syrian Arab Republic, is a country in West Asia located in the Eastern Mediterranean and the Levant. It is bounded by the Mediterranean Sea to the west, Turkey to the north, Iraq to the east and southeast, Jordan to the south, and Israel and Lebanon to the southwest. Cyprus lies to the west across the Mediterranean Sea. It is a unitary republic that consists of 14 governorates (subdivisions).
Complexity classIn computational complexity theory, a complexity class is a set of computational problems "of related resource-based complexity". The two most commonly analyzed resources are time and memory. In general, a complexity class is defined in terms of a type of computational problem, a model of computation, and a bounded resource like time or memory. In particular, most complexity classes consist of decision problems that are solvable with a Turing machine, and are differentiated by their time or space (memory) requirements.
Computational complexityIn computer science, the computational complexity or simply complexity of an algorithm is the amount of resources required to run it. Particular focus is given to computation time (generally measured by the number of needed elementary operations) and memory storage requirements. The complexity of a problem is the complexity of the best algorithms that allow solving the problem. The study of the complexity of explicitly given algorithms is called analysis of algorithms, while the study of the complexity of problems is called computational complexity theory.
GovernmentA government is the system or group of people governing an organized community, generally a state. In the case of its broad associative definition, government normally consists of legislature, executive, and judiciary. Government is a means by which organizational policies are enforced, as well as a mechanism for determining policy. In many countries, the government has a kind of constitution, a statement of its governing principles and philosophy.
TunisiaTunisia, officially the Republic of Tunisia, is the northernmost country in Africa. It is a part of the Maghreb region of North Africa, bordered by Algeria to the west and southwest, Libya to the southeast, and the Mediterranean Sea to the north and east. It features the archaeological sites of Carthage dating back to the 9th century BC, as well as the Great Mosque of Kairouan. Known for its ancient architecture, souks and blue coasts, it covers , and has a population of 12.1 million.
Arab worldThe Arab world (اَلْعَالَمُ الْعَرَبِيُّ al-ʿālam al-ʿarabī), formally the Arab homeland (اَلْوَطَنُ الْعَرَبِيُّ al-waṭan al-ʿarabī), also known as the Arab nation (اَلْأُمَّةُ الْعَرَبِيَّةُ al-ummah al-ʿarabīyyah), the Arabsphere, or the Arab states, comprises a vast group of countries, mainly located in West Asia and North Africa. While the majority of people in the Arab world are ethnically Arab, there are also significant populations of other ethnic groups such as Berbers, Kurds, Somalis and Nubians, among other groups.
Age of RevolutionThe Age of Revolution is a period from the late-18th to the mid-19th centuries during which a number of significant revolutionary movements occurred in most of Europe and the Americas. The period is noted for the change from absolutist monarchies to representative governments with a written constitution, and the creation of nation states. Influenced by the new ideas of the Enlightenment, the American Revolution (1765–1783) is usually considered the starting point of the Age of Revolution.
ProtestA protest (also called a demonstration, remonstration or remonstrance) is a public expression of objection, disapproval or dissent towards an idea or action, typically a political one. Protests can be thought of as acts of cooperation in which numerous people cooperate by attending, and share the potential costs and risks of doing so. Protests can take many different forms, from individual statements to mass political demonstrations.
Computational complexity theoryIn theoretical computer science and mathematics, computational complexity theory focuses on classifying computational problems according to their resource usage, and relating these classes to each other. A computational problem is a task solved by a computer. A computation problem is solvable by mechanical application of mathematical steps, such as an algorithm. A problem is regarded as inherently difficult if its solution requires significant resources, whatever the algorithm used.
Time complexityIn computer science, the time complexity is the computational complexity that describes the amount of computer time it takes to run an algorithm. Time complexity is commonly estimated by counting the number of elementary operations performed by the algorithm, supposing that each elementary operation takes a fixed amount of time to perform. Thus, the amount of time taken and the number of elementary operations performed by the algorithm are taken to be related by a constant factor.
LibyaLibya (ˈlɪbiə ; Lībiyā, liː.bi.jæː), officially the State of Libya (Dawlat Lībiyā), is a country in the Maghreb region in North Africa. It is bordered by the Mediterranean Sea to the north, Egypt to the east, Sudan to the southeast, Chad to the south, Niger to the southwest, Algeria to the west, and Tunisia to the northwest. Libya is made of three historical regions: Tripolitania, Fezzan, and Cyrenaica. With an area of almost , it is the fourth-largest country in Africa and the Arab world, and the 16th-largest in the world.
Syria (region)Syria (Hieroglyphic Luwian: 𔒂𔒠 Sura/i; Συρία) or Sham (ash-Shām) is the name of a historical region located east of the Mediterranean Sea in Western Asia, broadly synonymous with the Levant. Other synonyms are Greater Syria or Syria-Palestine. The region boundaries have changed throughout history. In modern times, the term "Syria" alone is used to refer to the Syrian Arab Republic. The term is originally derived from Assyria, an ancient civilization centered in northern Mesopotamia, modern-day Iraq.
South SudanSouth Sudan (suːˈdɑːn,_-ˈdæn), officially the Republic of South Sudan, is a landlocked country in Central Africa and politically grouped in Eastern Africa region. It is bordered by Ethiopia, Sudan, the Central African Republic, the Democratic Republic of the Congo, Uganda, and Kenya. Its population was estimated at 11,088,796 in 2023. Juba is the capital and largest city. South Sudan gained independence from Sudan on 9 July 2011, making it the most recent sovereign state or country with widespread recognition as of 2023.
Communist revolutionA communist revolution is a proletarian revolution inspired by the ideas of Marxism that aims to replace capitalism with communism. Depending on the type of government, the term socialism can be used to indicate an intermediate stage between Capitalism and Communism (especially in Marxist-Leninist views). The idea that a proletarian revolution is needed is a cornerstone of Marxism; Marxists believe that the workers of the world must unite and free themselves from capitalist oppression to create a world run by and for the working class.
