The Greek War of Independence, also known as the Greek Revolution of 1821 or the Greek Revolution, was a successful war of independence by Greek revolutionaries against the Ottoman Empire between 1821 and 1829. The Greeks were later assisted by the British Empire, Kingdom of France, and Russia, while the Ottomans were aided by their North African vassals, particularly the eyalet of Egypt. The war led to the formation of modern Greece. The revolution is celebrated by Greeks around the world as independence day on 25 March.

Greece came under Ottoman rule in the 15th century, in the decades before and after the fall of Constantinople. During the following centuries, there were sporadic but unsuccessful Greek uprisings against Ottoman rule. In 1814, a secret organization called Filiki Eteria (Society of Friends) was founded with the aim of liberating Greece, encouraged by the revolutionary fervor gripping Europe in that period. The Filiki Eteria planned to launch revolts in the Peloponnese, the Danubian Principalities, and Constantinople itself. The insurrection was planned for 25 March 1821 (in the Julian Calendar), the Orthodox Christian Feast of the Annunciation. However, the plans of Filiki Eteria were discovered by the Ottoman authorities, forcing the revolution to start earlier. The first revolt began on 6 March/21 February 1821 in the Danubian Principalities, but it was soon put down by the Ottomans. The events in the north urged the Greeks in the Peloponnese (Morea) into action and on 17 March 1821, the Maniots were first to declare war. In September 1821, the Greeks under the leadership of Theodoros Kolokotronis captured Tripolitsa. Revolts in Crete, Macedonia, and Central Greece broke out, but were eventually suppressed. Meanwhile, makeshift Greek fleets achieved success against the Ottoman navy in the Aegean Sea and prevented Ottoman reinforcements from arriving by sea.

Tensions soon developed among different Greek factions, leading to two consecutive civil wars. The Ottoman Sultan called in his vassal Muhammad Ali of Egypt, who agreed to send his son Ibrahim Pasha to Greece with an army to suppress the revolt in return for territorial gains. Ibrahim landed in the Peloponnese in February 1825 and brought most of the peninsula under Egyptian control by the end of that year. The town of Missolonghi fell in April 1826 after a year-long siege by the Turks. Despite a failed invasion of Mani, Athens also fell and the revolution looked all but lost.

At that point, the three Great powersRussia, Britain, and Francedecided to intervene, sending their naval squadrons to Greece in 1827. Following news that the combined OttomanEgyptian fleet was going to attack the island of Hydra, the allied European fleets intercepted the Ottoman navy at Navarino. After a tense week-long standoff, the Battle of Navarino led to the destruction of the OttomanEgyptian fleet and turned the tide in favor of the revolutionaries. In 1828 the Egyptian army withdrew under pressure of a French expeditionary force. The Ottoman garrisons in the Peloponnese surrendered, and the Greek revolutionaries proceeded to retake central Greece. Russia invaded the Ottoman Empire and forced it to accept Greek autonomy in the Treaty of Adrianople (1829). After nine years of war, Greece was finally recognized as an independent state under the London Protocol of February 1830. Further negotiations in 1832 led to the London Conference and the Treaty of Constantinople; these defined the final borders of the new state and established Prince Otto of Bavaria as the first king of Greece.

Cyprus ( (listen)), officially the Republic of Cyprus, is an island country in the eastern Mediterranean Sea south of the Anatolian Peninsula. It is the third-largest and third-most populous island in the Mediterranean, and is located south of Turkey, west of Syria, northwest of Lebanon, Israel, and the Gaza Strip (Palestine), north of Egypt, and southeast of Greece. Its capital and largest city is Nicosia and second largest is Limassol.

The earliest known human activity on the island dates to around the 10th millennium BC. Archaeological remains from this period include the well-preserved Neolithic village of Khirokitia, and Cyprus is home to some of the oldest water wells in the world. Cyprus was settled by Mycenaean Greeks in two waves in the 2nd millennium BC. As a strategic location in the Eastern Mediterranean, it was subsequently occupied by several major powers, including the empires of the Assyrians, Egyptians and Persians, from whom the island was seized in 333 BC by Alexander the Great. Subsequent rule by Ptolemaic Egypt, the Classical and Eastern Roman Empire, Arab caliphates for a short period, the French Lusignan dynasty and the Venetians was followed by over three centuries of Ottoman rule between 1571 and 1878 (de jure until 1914).Cyprus was placed under the UK's administration based on the Cyprus Convention in 1878 and was formally annexed by the UK in 1914. The future of the island became a matter of disagreement between the two prominent ethnic communities, Greek Cypriots, who made up 77% of the population in 1960, and Turkish Cypriots, who made up 18% of the population. From the 19th century onwards, the Greek Cypriot population pursued enosis, union with Greece, which became a Greek national policy in the 1950s. The Turkish Cypriot population initially advocated the continuation of the British rule, then demanded the annexation of the island to Turkey, and in the 1950s, together with Turkey, established a policy of taksim, the partition of Cyprus and the creation of a Turkish polity in the north. Following nationalist violence in the 1950s, Cyprus was granted independence in 1960. The crisis of 1963–64 brought further intercommunal violence between the two communities, displaced more than 25,000 Turkish Cypriots into enclaves: 56–59  and brought the end of Turkish Cypriot representation in the republic. On 15 July 1974, a coup d'état was staged by Greek Cypriot nationalists and elements of the Greek military junta in an attempt at enosis. This action precipitated the Turkish invasion of Cyprus on 20 July, which led to the capture of the present-day territory of Northern Cyprus and the displacement of over 150,000 Greek Cypriots and 50,000 Turkish Cypriots. A separate Turkish Cypriot state in the north was established by unilateral declaration in 1983; the move was widely condemned by the international community, with Turkey alone recognising the new state. These events and the resulting political situation are matters of a continuing dispute.

The Republic of Cyprus has de jure sovereignty over the entire island, including its territorial waters and exclusive economic zone, with the exception of the Sovereign Base Areas of Akrotiri and Dhekelia, which remain under the UK's control according to the London and Zürich Agreements. However, the Republic of Cyprus is de facto partitioned into two main parts: the area under the effective control of the Republic, located in the south and west and comprising about 59% of the island's area, and the north, administered by the self-declared Turkish Republic of Northern Cyprus, covering about 36% of the island's area. Another nearly 4% of the island's area is covered by the UN buffer zone. The international community considers the northern part of the island to be territory of the Republic of Cyprus occupied by Turkish forces. The occupation is viewed as illegal under international law and amounting to illegal occupation of EU territory since Cyprus became a member of the European Union.Cyprus is a major tourist destination in the Mediterranean. With an advanced, high-income economy and a very high Human Development Index, the Republic of Cyprus has been a member of the Commonwealth since 1961 and was a founding member of the Non-Aligned Movement until it joined the European Union on 1 May 2004. On 1 January 2008, the Republic of Cyprus joined the eurozone.
