Cultures in America timeline.

The Preclassic Period refers to the earliest phase of development in Mesoamerican civilizations, spanning roughly from 2000 BCE to 250 CE. This period is significant for laying the foundations of complex societies in the region, including the rise of agriculture, settled villages, and the early development of writing, art, and monumental architecture.

Olmec Civilization (1200 BCE – 400 BCE):
Location: Gulf Coast of Mexico (modern-day Veracruz and Tabasco).
Key Developments: The Olmecs are credited with establishing many cultural patterns seen in later Mesoamerican civilizations, such as ceremonial centers, monumental stone heads, and writing and calendar systems in the region. They also practiced early forms of trade, art, and religion.
Significance: Influenced civilizations through their advancements in writing, art, and religious practices.

The Classic Period (250 CE to 900 CE) marks the height of cultural, political, and architectural development in the region. This era saw the rise of some of the most famous and influential civilizations, including the Maya, Teotihuacan, and Zapotecs, who created sophisticated city-states, monumental architecture, advanced writing systems, and complex political organizations.

Teotihuacan Civilization (200 CE – 600 CE):
Location: Mexico City.
Key Developments: Teotihuacan was one of the largest cities. The city's monumental architecture, including the Pyramids of the Sun and the Moon, as well as its grid-based urban planning, made it a powerful economic, political, and religious center in Mesoamerica.
Significance: The influence of Teotihuacan reached across Mesoamerica, and its decline around 600 CE had consequences for the region's political and cultural landscape.

Zapotecs ( 200 CE - 900 CE )
Location: Oaxaca Valley, in the current state of Oaxaca, Mexico.
Characteristics: The Zapotecs built the city of Monte Albán, one of the first major urban centers in Mesoamerica. They stood out for their advancements in writing, architecture, and astronomy.
Contributions: They created one of the earliest writing systems in Mesoamerica and were experts in urban planning, as well as the construction of pyramids and plazas.

Maya Civilization (250 CE – 900 CE):
Location: Present-day southern Mexico, Guatemala, Belize, Honduras, and El Salvador.
Key Developments: The Maya civilization is known for its advanced achievements in hieroglyphics, mathematics (including the concept of zero), and astronomy (developing complex calendar systems). They built massive city-states like Tikal, Palenque, and Copán, with pyramids, temples, and palaces.
Significance: Contributed to science, art, and architecture.

The Postclassic Period (900 CE - 1521 CE) in Mesoamerican history marks the time after the decline of the great Classic Period civilizations, such as the Maya and Teotihuacan. This era was characterized by increased militarism, population shifts, political fragmentation, and the rise of new, powerful empires. It culminated with the arrival of the Spanish in the early 16th century.

Toltec Civilization (900 CE – 1150 CE):
Location: Central Mexico (Tula).
Key Developments: The Toltecs were known for their architectural and artistic achievements, including the Atlantean warrior statues at Tula. They influenced the Aztecs, who considered the Toltecs their cultural ancestors.
Significance: The Toltecs played a key role in the development of Mesoamerican culture during the Postclassic period, passing down military, religious, and artistic traditions.

Aztec Civilization (1325 CE – 1521 CE):
Location: Central Mexico (Tenochtitlán).
Key Developments: The Aztecs built a vast empire through military conquest and alliances. Their capital, Tenochtitlán, was in Lake Texcoco. The Aztecs are also known for their religious practices, including human sacrifice, and their complex social and political structures.
Significance: The Aztec Empire was one of the last great civilizations of Mesoamerica before the Spanish conquest.

Inca Civilization (1438 CE – 1533 CE):
Location: Andean region, stretching from Ecuador to Chile.
Key Developments: The Inca built the largest empire in pre-Columbian America, with advanced agricultural terraces, road systems, and monumental cities like Machu Picchu. They developed a system of centralized administration.
Significance: The Inca were the dominant power in the Andes before the Spanish conquest in 1533. Their engineering achievements and empire-building techniques were unparalleled.
