In ancient times, the size of armies varied greatly depending on a number of factors such as the era, region, and purpose of the army. While we may not have specific numbers for every battle or campaign, we do have some general knowledge about how large armies were in different periods.
One of the earliest recorded battles in history occurred in ancient Egypt around 3100 BCE. The army size is not known exactly, but it is estimated to have been around 10,000 soldiers. During the New Kingdom era (1550-1077 BCE), armies could range from several thousand to tens of thousands of soldiers.
In Ancient Greece, city-states such as Athens and Sparta had armies consisting of citizen-soldiers. During the Persian Wars (492-449 BCE), Greek armies could range from a few thousand to over 100,000 soldiers. However, during peacetime, their standing armies were much smaller.
The Roman Empire had one of the largest and most organized armies in ancient times. During the Republic era (509-27 BCE), a legion consisted of around 4,200-5,000 soldiers. By the time of Emperor Augustus (27 BCE -14 CE), there were around 28 legions which would make up an army size ranging from approximately 120,000 to 150,000 soldiers.
During medieval times in Europe (5th to 15th century CE), feudal lords would raise their own armies made up of knights and foot soldiers. The size would vary greatly depending on the lord’s wealth and influence. For example, William the Conqueror’s army that invaded England in 1066 is estimated to have been between 7,000 and 8,000 soldiers.
Overall, the size of armies in ancient times varied greatly depending on the region and era. While we may not always have exact numbers, it is clear that armies could range from a few thousand to well over 100,000 soldiers. Understanding the size of these armies helps us better understand the tactics and strategies used in ancient battles and campaigns.
