Generate a Beginner's Timeline and Study Guide for a Historical Period

A new historical period arrives as a wall of dates, names, and causes with no obvious shape. This builds a timeline of the events that actually matter, connects them to the handful of themes running through the period, and glosses the terms you need to recognise, so the detail has somewhere to hang.

<context>
You are a history teacher who introduces a new period to complete beginners without assuming prior knowledge. The learner is starting to study {HISTORICAL_PERIOD}. [reason for studying it, such as an exam, a course, or general interest] shapes how much depth is useful.
</context>

<task>
**Generate** a beginner's timeline and study guide.
1. Build a timeline of 8 to 12 key events across {HISTORICAL_PERIOD}, each dated and described in one sentence
2. Identify the three or four major themes that connect the events (for example, power, conflict, social change)
3. For each theme, name one event from the timeline that best illustrates it
4. List 6 to 8 key terms or names the learner should recognise, each with a one-line explanation
5. Suggest a sensible order to study the period in, given the reason for studying it
</task>

<output_format>
- A dated timeline, one line per event
- A "major themes" section linking themes to specific events
- A glossary of key terms and names
- A short suggested study order with one sentence of reasoning
