- 117,862 votesJesus (c. 4 BC – c. AD 30 / 33), also referred to as Jesus of Nazareth and Jesus Christ, was a first-century Jewish preacher and religious leader. He is the central figure of Christianity. Most Christians believe he is the incarnation of God the Son and the awaited Messiah (Christ) prophesied in the Old Testament.Virtually all modern scholars of antiquity agree that Jesus existed historically, although the quest for the historical Jesus has produced little agreement on the historical reliability of the Gospels and on how closely the Jesus portrayed in the Bible reflects the historical Jesus. Jesus was a Galilean Jew who was baptized by John the Baptist and began his own ministry. He preached orally and was often referred to as "rabbi". Jesus debated with fellow Jews on how to best follow God, engaged in healings, taught in parables and gathered followers. He was arrested and tried by the Jewish authorities, turned over to the Roman government, and crucified on the order of Pontius Pilate, the Roman prefect. After his death, his followers believed he rose from the dead, and the community they formed eventually became the early Church.Christian doctrines include the beliefs that Jesus was conceived by the Holy Spirit, was born of a virgin named Mary, performed miracles, founded the Christian Church, died by crucifixion as a sacrifice to achieve atonement for sin, rose from the dead, and ascended into Heaven, from where he will return. Most Christians believe Jesus enables people to be reconciled to God. The Nicene Creed asserts that Jesus will judge the living and the dead either before or after their bodily resurrection, an event tied to the Second Coming of Jesus in Christian eschatology. The great majority of Christians worship Jesus as the incarnation of God the Son, the second of three persons of the Trinity. A minority of Christian denominations reject Trinitarianism, wholly or partly, as non-scriptural. The birth of Jesus is celebrated annually on December 25 (or various dates in January by some eastern churches) as Christmas. His crucifixion is honored on Good Friday and his resurrection on Easter. The widely used calendar era "AD", from the Latin anno Domini ("in the year of the Lord"), and the equivalent alternative "CE", are based on the approximate birthdate of Jesus.Jesus is also revered in non-Christian religions. In Islam, Jesus (commonly transliterated as Isa) is considered one of God's important prophets and the Messiah. Muslims believe Jesus was a bringer of scripture and was born of a virgin, but was not the son of God. The Quran states that Jesus never claimed divinity. Most Muslims do not believe that he was crucified, but that he was physically raised into Heaven by God. In contrast, Judaism rejects the belief that Jesus was the awaited Messiah, arguing that he did not fulfill Messianic prophecies, and was neither divine nor resurrected.
- 219,829 votesGaius Julius Caesar (12 July 100 BC – 15 March 44 BC) was a Roman general and statesman who played a critical role in the events that led to the demise of the Roman Republic and the rise of the Roman Empire. In 60 BC, Caesar, Crassus and Pompey formed the First Triumvirate, a political alliance that dominated Roman politics for several years. After assuming control of government, Caesar began a program of social and governmental reforms, including the creation of the Julian calendar. Caesar was an accomplished author and historian as well as a statesman; much of his life is known from his own accounts of his military campaigns. Caesar is considered by many historians to be one of the greatest military commanders in history. He has frequently appeared in literary and artistic works, and his political philosophy, known as Caesarism, inspired politicians into the modern era.
- 327,824 votesAlexander III of Macedon (Greek: Αλέξανδρος Γʹ ὁ Μακεδών; 20/21 July 356 BC – 10/11 June 323 BC), commonly known as Alexander the Great (Ancient Greek: Ἀλέξανδρος ὁ Μέγας, romanized: Aléxandros ho Mégas), was a king (basileus) of the ancient Greek kingdom of Macedon and a member of the Argead dynasty. He was born in Pella in 356 BC and succeeded his father Philip II to the throne at the age of 20. He spent most of his ruling years on an unprecedented military campaign through Asia and northeast Africa, and by the age of thirty he had created one of the largest empires of the ancient world, stretching from Greece to northwestern India. He was undefeated in battle and is widely considered one of history's most successful military commanders.During his youth, Alexander was tutored by Aristotle until age 16. After Philip's assassination in 336 BC, he succeeded his father to the throne and inherited a strong kingdom and an experienced army. Alexander was awarded the generalship of Greece and used this authority to launch his father's pan-Hellenic project to lead the Greeks in the conquest of Persia. In 334 BC, he invaded the Achaemenid Empire (Persian Empire) and began a series of campaigns that lasted 10 years. Following the conquest of Anatolia, Alexander broke the power of Persia in a series of decisive battles, most notably the battles of Issus and Gaugamela. He subsequently overthrew Persian King Darius III and conquered the Achaemenid Empire in its entirety. At that point, his empire stretched from the Adriatic Sea to the Indus River. Alexander endeavored to reach the "ends of the world and the Great Outer Sea" and invaded India in 326 BC, winning an important victory over the Pauravas at the Battle of the Hydaspes. He eventually turned back at the demand of his homesick troops, dying in Babylon in 323 BC, the city that he planned to establish as his capital, without executing a series of planned campaigns that would have begun with an invasion of Arabia. In the years following his death, a series of civil wars tore his empire apart, resulting in the establishment of several states ruled by the Diadochi: Alexander's surviving generals and heirs. Alexander's legacy includes the cultural diffusion and syncretism which his conquests engendered, such as Greco-Buddhism. He founded some twenty cities that bore his name, most notably Alexandria in Egypt. Alexander's settlement of Greek colonists and the resulting spread of Greek culture in the east resulted in a new Hellenistic civilization, aspects of which were still evident in the traditions of the Byzantine Empire in the mid-15th century AD and the presence of Greek speakers in central and far eastern Anatolia until the 1920s. Alexander became legendary as a classical hero in the mold of Achilles, and he features prominently in the history and mythic traditions of both Greek and non-Greek cultures. He became the measure against which military leaders compared themselves, and military academies throughout the world still teach his tactics. He is often ranked among the most influential people in history.
- 42,647 votesGalileo Galilei ( GAL-il-AY-oh, also US: -EE-oh, Italian: [ɡaliˈlɛːo ɡaliˈlɛi]; 15 February 1564 – 8 January 1642) was an astronomer, physicist and engineer, sometimes described as a polymath from Pisa. Galileo has been called the "father of observational astronomy", the "father of modern physics", the "father of the scientific method", and the "father of modern science".Galileo studied speed and velocity, gravity and free fall, the principle of relativity, inertia, projectile motion and also worked in applied science and technology, describing the properties of pendulums and "hydrostatic balances", inventing the thermoscope and various military compasses, and using the telescope for scientific observations of celestial objects. His contributions to observational astronomy include the telescopic confirmation of the phases of Venus, the observation of the four largest satellites of Jupiter, the observation of Saturn's rings, and the analysis of sunspots. Galileo's championing of heliocentrism and Copernicanism was controversial during his lifetime, when most subscribed to geocentric models such as the Tychonic system. He met with opposition from astronomers, who doubted heliocentrism because of the absence of an observed stellar parallax. The matter was investigated by the Roman Inquisition in 1615, which concluded that heliocentrism was "foolish and absurd in philosophy, and formally heretical since it explicitly contradicts in many places the sense of Holy Scripture". Galileo later defended his views in Dialogue Concerning the Two Chief World Systems (1632), which appeared to attack Pope Urban VIII and thus alienated him and the Jesuits, who had both supported Galileo up until this point. He was tried by the Inquisition, found "vehemently suspect of heresy", and forced to recant. He spent the rest of his life under house arrest. While under house arrest, he wrote Two New Sciences, in which he summarized work he had done some forty years earlier on the two sciences now called kinematics and strength of materials.
- 52,719 votesSocrates (; Ancient Greek: Σωκρᾰ́της, romanized: Sōkrátēs, [sɔːkrátɛːs]; c. 470 – 399 BC) was a classical Greek (Athenian) philosopher credited as one of the founders of Western philosophy, and as being the first moral philosopher of the Western ethical tradition of thought. An enigmatic figure, he made no writings, and is known chiefly through the accounts of classical writers writing after his lifetime, particularly his students Plato and Xenophon. Other sources include the contemporaneous Antisthenes, Aristippus, and Aeschines of Sphettos. Aristophanes, a playwright, is the main contemporary author to have written plays mentioning Socrates during Socrates' lifetime, though a fragment of Ion of Chios' Travel Journal provides important information about Socrates' youth.Plato's dialogues are among the most comprehensive accounts of Socrates to survive from antiquity, from which Socrates has become renowned for his contributions to the fields of ethics and epistemology. It is this Platonic Socrates who lends his name to the concepts of Socratic irony and the Socratic method, or elenchus. However, questions remain regarding the distinction between the real-life Socrates and Plato's portrayal of Socrates in his dialogues. Socrates exerted a strong influence on philosophers in later antiquity and in the modern era. Depictions of Socrates in art, literature and popular culture have made him one of the most widely known figures in the Western philosophical tradition.
- 620,367 votesSir Winston Leonard Spencer-Churchill (30 November 1874 – 24 January 1965) was a British politician, army officer, and writer. He was Prime Minister of the United Kingdom from 1940 to 1945, when he led Britain to victory in the Second World War, and again from 1951 to 1955. Churchill represented five constituencies during his career as a Member of Parliament (MP). Ideologically an economic liberal and imperialist, for most of his career he was a member of the Conservative Party, which he led from 1940 to 1955, but from 1904 to 1924 was a member of the Liberal Party. Of mixed English and American parentage, Churchill was born in Oxfordshire to a wealthy, aristocratic family. Joining the British Army, he saw action in British India, the Anglo–Sudan War, and the Second Boer War, gaining fame as a war correspondent and writing books about his campaigns. Elected an MP in 1900, initially as a Conservative, he defected to the Liberals in 1904. In H. H. Asquith's Liberal government, Churchill served as President of the Board of Trade, Home Secretary, and First Lord of the Admiralty, championing prison reform and workers' social security. During the First World War, he oversaw the Gallipoli Campaign; after it proved a disaster, he resigned from government and served in the Royal Scots Fusiliers on the Western Front. In 1917, he returned to government under David Lloyd George as Minister of Munitions, then as Secretary of State for War and Air, and finally for the Colonies, overseeing the Anglo-Irish Treaty and Britain's Middle East policy. After two years out of Parliament, he served as Chancellor of the Exchequer in Stanley Baldwin's Conservative government, returning the pound sterling in 1925 to the gold standard at its pre-war parity, a move widely seen as creating deflationary pressure on the UK economy. Out of office during the 1930s, Churchill took the lead in calling for British rearmament to counter the growing threat from Nazi Germany. At the outbreak of the Second World War he was re-appointed First Lord of the Admiralty. In 1940 he became prime minister, replacing Neville Chamberlain. Churchill oversaw British involvement in the Allied war effort against Germany and the Axis powers, resulting in victory in 1945. His wartime leadership was widely praised, although acts like the Bombing of Dresden and his wartime response to the Bengal famine generated controversy. After the Conservatives' defeat in the 1945 general election, he became Leader of the Opposition. Amid the developing Cold War with the Soviet Union, he publicly warned of an "iron curtain" of Soviet influence in Europe and promoted European unity. Re-elected Prime Minister in 1951, his second term was preoccupied with foreign affairs, including the Malayan Emergency, Mau Mau Uprising, Korean War, and a UK-backed Iranian coup. Domestically his government emphasised house-building and developed a nuclear weapon. In declining health, Churchill resigned as prime minister in 1955, although he remained an MP until 1964. Upon his death in 1965, he was given a state funeral. Widely considered one of the 20th century's most significant figures, Churchill remains popular in the UK and Western world, where he is seen as a victorious wartime leader who played an important role in defending Europe's liberal democracy from the spread of fascism. Also praised as a social reformer and writer, among his many awards was the Nobel Prize in Literature. Conversely, his imperialist views and comments on race, as well as his sanctioning of human rights abuses in the suppression of anti-imperialist movements seeking independence from the British Empire, have generated considerable controversy.
