The Babylonian Empire and the Assyrian Empire were two of the most powerful civilizations in ancient Mesopotamia, each with its own extent and influence. To answer the question directly: no, the Babylonian Empire was generally not bigger than the Assyrian Empire in terms of land area.
The Assyrian Empire, at its peak around the 7th century BCE, spanned a vast territory that included parts of modern-day Iraq, Syria, Turkey, and Iran. It was known for its military prowess and administrative efficiency, allowing it to control a substantial area that extended across the fertile lands of the Near East.
In contrast, the Babylonian Empire, especially during its height under Nebuchadnezzar II from 605-562 BCE, focused more on cultural and economic achievements rather than vast territorial expansion. While it held significant influence and controlled key trade routes, its territorial extent was less than that of Assyria.
To summarize, while both empires had a profound impact on history and culture, the Assyrian Empire was larger in scope compared to the Babylonian Empire during their respective peaks.
