This 24 x 36" wall poster covers 3000 BCE to the present. It was fully revised and updated in 2012 and as such represents 21st century scholars current knowledge of the past (for example, potential linkages between Indo-European groups are shown as well as several newly discovered cultures such as the Oxus Civilization). Over 100 major empires, kingdoms, and civilizations are displayed in a colorful synchronoptic (side-by-side) format so that one can quickly see how different events in different places relate to each other and get a broad sense of the general "flow" of history. Over 500 facts are shown on the timeline, including famous people, important achievements, major wars, specific eras of human development, and natural disasters. The insets even include events from the Big Bang through human prehistory as well as potential future events from the present to the year 2100 and beyond. On the main chart, the names of each century (e.g. - 3rd century CE) are included alongside the dates (e.g. - 200-300 CE) in order to avoid any confusion and, unlike many other such timelines, the units of time remain equidistant in order to provide a proper comparison between ancient empires and modern ones. A conscious effort has also been made to make the chart less Eurocentric than other popular (but now terribly outdated) timelines and thus what was happening in India, China, Africa, and the Americas is shown alongside what was happening in the Middle East and Europe.
