Answer:
To study history is to study change: historians are experts in examining and interpreting human identities and transformations of societies and civilizations over time. They use a range of methods and analytical tools to answer questions about the past and to reconstruct the diversity of past human experience: how profoundly people have differed in their ideas, institutions, and cultural practices; how widely their experiences have varied by time and place, and the ways they have struggled while inhabiting a shared world. Historians use a wide range of sources to weave individual lives and collective actions into narratives that bring critical perspectives on both our past and our present. Studying history helps us understand and grapple with complex questions and dilemmas by examining how the past has shaped (and continues to shape) global, national, and local relationships between societies and people.
