Mesoamerican chronology in the context of "Toltec"

The Olmecs (/ˈɒlmɛks, ˈoʊl-/) or Olmec were an early major Mesoamerican civilization, flourishing in the modern-day Mexican states of Veracruz and Tabasco from roughly 1200 to 400 BC during Mesoamerica's formative period. They were initially centered at the site of their development in San Lorenzo Tenochtitlán, but moved to La Venta in the 10th century BC following the decline of San Lorenzo. By about 400 BC the major centres of the Olmec civilization had been abandoned, and the population of the eastern half of the Olmec heartland dropped precipitously. The settlement density in that area remained much lower than during the height of Olmec dominance, and only intermittent occupation is evident until much later. Although the Olmec cultural style waned, elements of their tradition lived on in successor societies.

Among other "firsts", the Olmec appeared to practice ritual bloodletting and played the Mesoamerican ballgame, hallmarks of nearly all subsequent Mesoamerican societies. The aspect of the Olmecs most familiar now is their artwork, particularly the colossal heads. The Olmec civilization was first defined through artifacts which collectors purchased on the pre-Columbian art market in the late 19th and early 20th centuries. Olmec artworks are considered among ancient America's most striking.

Science in the ancient world encompasses the earliest history of science from the protoscience of prehistory and ancient history to late antiquity. In ancient times, culture and knowledge were passed through oral tradition. The development of writing further enabled the preservation of knowledge and culture, allowing information to spread accurately.

The earliest scientific traditions of the ancient world developed in the Ancient Near East, with Ancient Egypt and Babylonia in Mesopotamia. Later traditions of science during classical antiquity were advanced in ancient Persia, Greece, Rome, India, China, and Mesoamerica. Aside from alchemy and astrology that waned in importance during the Age of Enlightenment, civilizations of the ancient world laid the roots of modern sciences.

The 2nd millennium BC spanned the years 2000 BC to 1001 BC. In the Ancient Near East, it marks the transition from the Middle to the Late Bronze Age.The Ancient Near Eastern cultures are well within the historical era:The first half of the millennium is dominated by the Middle Kingdom of Egypt and Babylonia. The alphabet develops. At the center of the millennium, a new order emerges with Mycenaean Greek dominance of the Aegean and the rise of the Hittite Empire. The end of the millennium sees the Bronze Age collapse and the transition to the Iron Age.

Other regions of the world are still in the prehistoric period. In Europe, the Beaker culture introduces the Bronze Age, presumably associated with Indo-European expansion. The Indo-Iranian expansion reaches the Iranian plateau and onto the Indian subcontinent (Vedic India), propagating the use of the chariot. Mesoamerica enters the Pre-Classic (Olmec) period. North America is in the late Archaic stage. In Maritime Southeast Asia, the Austronesian expansion reaches Micronesia. In Sub-Saharan Africa, the Bantu expansion begins.

The Spanish conquest of the Maya was a protracted conflict during the Spanish colonisation of the Americas, in which the Spanish conquistadores and their allies gradually incorporated the territory of the Late Postclassic Maya states and polities into the colonial Viceroyalty of New Spain. The Maya occupied the Maya Region, an area that is now part of the modern countries of Mexico, Guatemala, Belize, Honduras and El Salvador; the conquest began in the early 16th century and is generally considered to have ended in 1697.

Before the conquest, Maya territory contained a number of competing kingdoms. Many conquistadors viewed the Maya as infidels who needed to be forcefully converted and pacified, despite the achievements of their civilization. The first contact between the Maya and European explorers came in 1502, during the fourth voyage of Christopher Columbus, when his brother Bartholomew encountered a canoe. Several Spanish expeditions followed in 1517 and 1519, making landfall on various parts of the Yucatán coast. The Spanish conquest of the Maya was a prolonged affair; the Maya kingdoms resisted integration into the Spanish Empire with such tenacity that their defeat took almost two centuries. The Itza Maya and other lowland groups in the Petén Basin were first contacted by Hernán Cortés in 1525, but remained independent and hostile to the encroaching Spanish until 1697, when a concerted Spanish assault led by Martín de Urzúa y Arizmendi finally defeated the last independent Maya kingdom.

Copán is an archaeological site of the Maya civilization in the Copán Department of western Honduras, not far from the border with Guatemala. It is one of the most important sites of the Maya civilization, which was not excavated until the 19th century. The ruined citadel and imposing public squares reveal the three main stages of development before the city was abandoned in the early 10th century.

This ancient Maya city mirrors the beauty of the physical landscapes in which it flourished—a fertile, well-watered mountain valley in western Honduras at an elevation of 600 meters (1,970 feet) above mean sea level. It was the capital city of a major Classic period kingdom from the 5th to 9th centuries AD. The city was in the extreme southeast of the Mesoamerican cultural region, on the frontier with the Isthmo-Colombian cultural region, and was almost surrounded by non-Maya peoples.

The Mayan architecture of the Maya civilization spans across several thousands of years, several eras of political change, and architectural innovation before the Spanish colonization of the Americas. Often, the buildings most dramatic and easily recognizable as creations of the Maya peoples are the step pyramids of the Terminal Preclassic Maya period and beyond. Based in general Mesoamerican architectural traditions, the Maya utilized geometric proportions and intricate carving to build everything from simple houses to ornate temples. This article focuses on the more well-known pre-classic and classic examples of Maya architecture. The temples like the ones at Palenque, Tikal, and Uxmal represent a zenith of Maya art and architecture. Through the observation of numerous elements and stylistic distinctions, remnants of Maya architecture have become an important key to understanding their religious beliefs and culture as a whole.

Maya astronomy is the study of the Moon, planets, Milky Way, Sun, and astronomical phenomena by the Precolumbian Maya civilization of Mesoamerica.The Classic Maya in particular developed some of the most accurate pre-telescope astronomy in the world, aided by their fully developed writing system and their positional numeral system, both of which are fully indigenous to Mesoamerica. The Classic Maya understood many astronomical phenomena: for example, their estimate of the length of the synodic month was more accurate than Ptolemy's, and their calculation of the length of the tropical solar year was more accurate than that of the Spanish when the latter first arrived. Many temples from the Maya architecture have features oriented to celestial events.
