Why is it difficult for historians to find info about enslaved people?

Historians often face challenges in finding information about enslaved people due to the limited and biased nature of historical records. Many enslaved individuals were not considered legal persons and therefore lacked formal documentation, such as birth certificates or personal narratives. Additionally, records that do exist, often created by slave owners or society at large, may reflect the perspectives and biases of those in power, leading to a skewed understanding of enslaved people's lives and experiences. This scarcity and bias in the historical record make it difficult to fully reconstruct their stories and contributions.
