Key insights

History is structured by dividing time into distinct ages based on significant events.

• The study of history helps us understand past civilizations and societies.
• Historians use units like years and centuries, often written in Roman numerals, to organize time.
• The calendar is referenced from the birth of Jesus Christ, with 'Before Christ' (BC) and 'Anno Domini' (AD) designations.
• Five major historical ages are recognized: Prehistory, Ancient, Medieval, Modern, and Contemporary.

Each historical age is defined by a pivotal event that marked a significant shift in human civilization.

• Prehistory began with the emergence of humans.
• The invention of writing marks the beginning of the Ancient Age.
• The fall of the Roman Empire signifies the start of the Middle Ages.

Historical understanding relies on various sources, categorized as written and non-written.

• Written sources include documents, laws, newspapers, letters, and literary works.
• Non-written sources encompass oral traditions (songs, interviews), graphic materials (photographs, maps, art), and material objects (tools, pottery, buildings).
• Archives and museums are key repositories for preserving historical sources.
