PDF

Overview

This lesson plan introduces King Arthur through Geoffrey of Monmouth’s History of the Kings of Britain, focusing on how Arthur symbolizes a Celtic-British vision of a united realm and the emergence of monarchy in Britain. Students will place Arthur in a historical context, distinguish British from English identities, and discuss how Christianity shapes leadership and national identity in the Early Middle Ages.

Key Concepts

  • Arthur as a symbolic founder of a united Britain, not just a legend
  • Geoffrey of Monmouth as a compiler who shapes a coherent Arthurian narrative
  • The distinction between British and English identities in the narrative
  • The monarchy and Christianity as foundational to British identity

Warm-Up Activity

Have students read lines 5–19 of Tennyson’s The Coming of Arthur (from Idylls of the King) to discuss: What state was England in before Arthur? Why does Arthur matter to the British imagination?

Guiding Questions for Discussion & Writing

  1. Merlin’s role: What purpose does Merlin serve in this history?
  2. Stonehenge: What is its significance in the Arthurian story?
  3. Pendragon name: How does the name Pendragon arise and why does it matter?
  4. Subduing the realm: How is Arthur able to bring the realm under one rule?
  5. Christian king: How is Arthur portrayed as a defender of Christianity? What virtues does he embody?
  6. Leadership ideal: Compare Merlin, Uther, Arthur, and other rulers. What makes an ideal leader in Geoffrey of Monmouth?
  7. Christianity’s place: How has Christianity shaped the culture and politics of Britain by the time this history is written?

Teacher’s Tips (for Context and Framing)

  • Explain that many Arthurian elements (knighthood, the Holy Grail, Lancelot, Gawain) belong to later medieval imagination; this chapter presents an Early Middle Ages seed of the legend.
  • Clarify the distinction between British and English: Arthur is British, born from resisting Anglo-Saxon invasions; the English identity develops later after the Norman conquest (1066).
  • When addressing Question 5, connect to earlier discussions of monarchy and Christianity, including Theodosius, Augustine, and other medieval ideas about two cities and Christian kingship.
  • Note that a later unit will cover the Norman impact and the emergence of the English as a distinct political culture; this chapter is about origins and seeds of identity.

Assessment/Activities

  • Short essay: How does Geoffrey of Monmouth use Arthur to imagine a united Britain? What elements are used to legitimize kingship and Christian leadership?
  • Debate: Is Arthur more a historical figure or a national myth? Use textual evidence from the chapter to support your position.
  • Creative brief: Write a modern school motto or pledge inspired by Arthurian values (as depicted in Geoffrey’s narrative) that reflects unity, duty, and faith.

Learning Outcomes

  • Students will identify Arthur’s role in the Celtic vision of Britain and contrast it with later medieval Arthurian legends.
  • Students will articulate how Geoffrey of Monmouth links monarchy and Christianity to national identity.
  • Students will analyze how historical narrative can shape cultural memory and identity over time.
