Bronze Age
The earliest known Ugarit contact with Egypt (and the first exact dating of Ugaritic civilization) comes from a carnelian bead identified with the Middle Kingdom pharaoh Senusret I, 1971–1926 BC. A stela and a statuette from the Egyptian pharaohs Senusret III and Amenemhet III have also been found. However, it is unclear at what time these monuments got to Ugarit. In the Amarna letters, messages from Ugarit BC written by Ammittamru I, Niqmaddu II, and his queen, were discovered. From the 16th to the 13th century BC, Ugarit remained in constant touch with Egypt and Cyprus (named Alashiya).
History of the Maya civilization
The history of Maya civilization is divided into three principal periods: the Preclassic, Classic and Postclassic periods; these were preceded by the Archaic Period, which saw the first settled villages and early developments in agriculture. Modern scholars regard these periods as arbitrary divisions of chronology of the Maya civilization, rather than indicative of cultural evolution or decadence. Definitions of the start and end dates of period spans can vary by as much as a century, depending on the author. The Preclassic lasted from approximately 2000 BC to approximately 250 AD; this was followed by the Classic, from 250 AD to roughly 950 AD, then by the Postclassic, from 950 AD to the middle of the 16th century. Each period is further subdivided:
