World population from 10,000 BCE to 2,000 CE. The vertical (population) scale is logarithmic. The history of the world is the history of humanity, beginning with the Paleolithic Era. Distinct from the history of the Earth (which includes early geologic history and prehuman biological eras), world history comprises the study of archaeological and written records, from ancient times on. Ancient recorded history begins with the invention of writing. However, the roots of civilization reach back to the period before the invention of writing. Outside the Old World, including ancient China and ancient India, historical timelines unfolded differently. Prehistory Early humans Modern humans spread rapidly from Africa into the frost-free zones of Europe and Asia around 60,000 years ago. The rapid expansion of humankind to North America and Oceania took place at the climax of the most recent Ice Age, when temperate regions of today were extremely inhospitable.

Ancient GreeceThe Parthenon, a temple dedicated to Athena, located on the Acropolis in Athens, is one of the most representative symbols of the culture and sophistication of the ancient Greeks. Ancient Greece was a Greek civilization belonging to a period of Greek history that lasted from the Archaic period of the 8th to 6th centuries BC to the end of antiquity (ca. 600 AD). Immediately following this period was the beginning of the Early Middle Ages and the Byzantine era. Included in ancient Greece is the period of Classical Greece, which flourished during the 5th to 4th centuries BC. Classical Greece began with the repelling of a Persian invasion by Athenian leadership. Classical Greek culture, especially philosophy, had a powerful influence on the Roman Empire, which carried a version of it to many parts of the Mediterranean Basin and Europe, for which reason Classical Greece is generally considered to be the seminal culture which provided the foundation of modern Western culture.
Middle AgesIn European history, the Middle Ages, or Medieval period, lasted from the 5th to the 15th century. It began with the collapse of the Western Roman Empire and merged into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: Antiquity, Medieval period, and Modern period. The Medieval period is itself subdivided into the Early, the High, and the Late Middle Ages. Depopulation, deurbanisation, invasion, and movement of peoples, which had begun in Late Antiquity, continued in the Early Middle Ages. During the High Middle Ages, which began after AD 1000, the population of Europe increased greatly as technological and agricultural innovations allowed trade to flourish and the Medieval Warm Period climate change allowed crop yields to increase.

If you are interested in knowing when it is ready, be sure to subscribe to our newsletter! In this post I'll teach you how to have perfect recall of lists of items. Length is not much of an issue, it can be your shopping list if 10 items or it can be a list with 50, 100 or even 1000. The technique we'll be learning is called the memory palace, and is also known as the method of loci (for the latin word locus meaning place) and also the mind palace. The memory palace The memory palace technique began in the 5th century B.C., when Simonides of Ceos, poet, was attending an unfortunate banquet in Thessalia. Think about it: It is not hard to remember who sits beside the host, where your friends sit, who is beside them and so on. The memory palace is well suited to how our brains have evolved. Remembering lists may sound lame, who wants to memorise a list...? Your first memory palace: building and filling Begin with the list. Final words
CeltsDiachronic distribution of Celtic peoples: core Hallstatt territory, by the 6th century BC maximal Celtic expansion, by 275 BC Lusitanian area of Iberia where Celtic presence is uncertain The Celts (/ˈkɛlts/, occasionally /ˈsɛlts/, see pronunciation of Celtic) or Kelts were an ethnolinguistic group of tribal societies in Iron Age and Medieval Europe who spoke Celtic languages and had a similar culture, although the relationship between the ethnic, linguistic and cultural elements remains uncertain and controversial. The earliest undisputed direct examples of a Celtic language are the Lepontic inscriptions, beginning in the 6th century BC. Continental Celtic languages are attested almost exclusively through inscriptions and place-names. Names and terminology Continental Celts are the Celtic-speaking people of mainland Europe and Insular Celts are the Celtic-speaking peoples of the British and Irish islands and their descendants. Origins Overview of the Hallstatt and La Tène cultures:
History of the alphabetThe history of alphabetic writing goes back to the consonantal writing system used for Semitic languages in the Levant in the 2nd millennium B.C. Most or nearly all alphabetic scripts used throughout the world today ultimately go back to this Semitic proto-alphabet. Its first origins can be traced back to a Proto-Sinaitic script developed in Ancient Egypt to represent the language of Semitic-speaking workers in Egypt. This script was partly influenced by the older Egyptian hieratic, a cursive script related to Egyptian hieroglyphs. Mainly through Phoenician and Aramaic, two closely related members of the Semitic family of scripts that were in use during the early first millennium BC, the Semitic alphabet became the ancestor of multiple writing systems across the Middle East, Europe, northern Africa and South Asia. Pre-history Two scripts are well attested from before the end of the fourth millennium BCE: Mesopotamian cuneiform and Egyptian hieroglyphs. Predecessors
