Why were peasants forced to fight?

Peasants were often forced to fight due to the feudal system, where lords needed soldiers to defend their lands and assert control over territories. In many cases, they had no choice but to serve in the military as part of their obligations to their lords, who provided protection and land in return. Additionally, during times of war or crisis, governments would conscript peasants to bolster their armies, further compelling them to participate in conflicts despite their lack of resources or training.
