The Etruscan Civilization flourished in ancient Italy from the 8th to the 3rd century BCE, primarily in the region known as Etruria, which is now part of modern Tuscany. The Etruscans were known for their advanced culture, including impressive architecture, art, and a unique language. They played a significant role in the development of early Roman society, influencing aspects such as religion, governance, and urban planning. Etruscan society was organized into city-states, each ruled by a king or a council. They were skilled in metalworking and trade, establishing connections with other cultures, including the Greeks and Phoenicians. The civilization began to decline in the 4th century BCE, largely due to the expansion of the Roman Republic.
