- The siege of Tyre was orchestrated by Alexander the Great in 332 BC during his campaigns against the Persians. The Macedonian army was unable to capture the city, which was a strategic coastal base on the Mediterranean Sea, through conventional means because it was on an island and had walls right up to the sea. Alexander responded to this problem by first blockading and besieging Tyre for seven months, and then by building a causeway and placing siege towers with catapults built on top at the end after his soldiers discovered that they could not extend it any further due to a steep drop under the surface of the water. This allowed him to breach the fortifications.
- Karl Marx (Wikipedia)
Karl Marx (German: [maʁks]; 5 May 1818 – 14 March 1883) was a German-born philosopher, political theorist, economist, historian, sociologist, journalist, and revolutionary socialist. His best-known works are the 1848 pamphlet The Communist Manifesto (with Friedrich Engels) and his three-volume Das Kapital (1867–1894); the latter employs his critical approach of historical materialism in an analysis of capitalism, in the culmination of his intellectual endeavours. Marx’s ideas and their subsequent development, collectively known as Marxism, have had enormous influence on modern intellectual, economic and political history.
