For how many years was the western civilization powerful?

Western civilization has seen periods of significant power and influence over many centuries, particularly from the rise of the Roman Empire around 27 BC to the present day. Key phases include the Middle Ages, the Renaissance, the Age of Enlightenment, and the Industrial Revolution, with notable dominance from the 16th to the 20th centuries. While it's challenging to pinpoint an exact number of years, one could argue that Western civilization has been a dominant force for over 2,000 years, particularly in terms of cultural, political, and economic influence globally.
