Halloween Folklore Lesson for Students: Tracing Samhain
The Library of Congress guide summarizes Halloween's roots in a single line, describing its origins as "an ancient, pre-Christian Celtic festival of the dead" (Library of Congress). This Halloween folklore lesson for students does not try to settle that whole story. It walks through one specific, checkable piece of it: whether Christian feast days placed on November 1 and 2 were meant to intentionally replace the Gaelic festival of Samhain. By the end, students will be able to separate a source's statement from the evidence that actually backs it up.
The same guide asserts that November feast days "were intended to substitute for Samhain and ultimately to replace it" (LOC). Wikipedia's Samhain entry presents a different level of support for the same period: it notes that churches in Gaelic Ireland and Anglo-Saxon Northumbria held an all-saints feast by roughly 800, without addressing whether the timing was chosen to erase Samhain (Wikipedia). One source states intent outright. The other supplies dates and stays quiet on intent. That gap is the whole reason to look closer instead of repeating either source's framing.
This lesson works for grades 6 through 8 using two preselected excerpts, and for grades 9 through 12 locating an additional source independently, though that grade split is this lesson's own instructional recommendation rather than a rule drawn from any single source. Teachers and tutors can run the core activity as modeled on the PBS NewsHour Classroom lateral-reading lesson, built for grades 6 through 12 in roughly 45 minutes. Students leave with a citation-log template, an evidence table, an extension covering three more fragments, and assessment criteria built around their own conclusions rather than fill-in-the-blank sentences.
Why "Halloween comes from Samhain" is four separate claims

The umbrella claim breaks into at least four testable pieces: what early sources actually say about Samhain itself, whether church feast days were intended to replace it, what continuity or blending the evidence shows between the two, and when related customs reached North America.
This lesson works through the replacement question in full depth and treats the other three as a shorter extension for a separate session. Wikipedia's Samhain entry supplies the evidence anchoring that split: a medieval Irish narrative describing a weeklong Samhain observance, a dated claim about churches marking November 1 by around 800, and a claim that most North American Halloween customs arrived with 19th-century Irish and Scottish immigrants (Wikipedia). All three come from the same encyclopedia synthesis, which means a thorough student check would trace Wikipedia's own footnotes back to the sources it's drawing from, rather than stop at the summary.
Splitting the claim first stops students from simply accepting or rejecting one finished narrative. It forces the question: which piece does this particular source actually support?
Halloween folklore source analysis: testing the "replacement" claim

Start with a search question: do available sources show that church authorities placed feast days on November 1 and 2 specifically to replace Samhain, or only that the two came to occupy the same time of year?
The 45-minute core activity uses exactly two sources, read in full by students:
- The Library of Congress's Halloween guide, an institutional educational summary that states the replacement directly: feast days "were intended to substitute for Samhain and ultimately to replace it" (LOC).
- Wikipedia's Samhain entry, an encyclopedia synthesis useful for orientation and dates but not a final citation. It states churches in Ireland and Northumbria held an all-saints feast by roughly 800, and that the Frankish Empire formally adopted November 1 in 835, without addressing whether the timing was meant to erase Samhain (Wikipedia).
Students working at the high school level should treat Wikipedia's synthesis as a starting point and check its footnotes for the underlying historical sources behind the 800 and 835 dates, rather than cite the encyclopedia entry as the last word.
Two optional pieces extend the lesson beyond these two sources, and each has a different classroom role. A 1982 audio lecture and companion essay by folklorist Jack Santino sits directly on the same Library of Congress guide page, below its historical summary (LOC). The page describes it as addressing "the origins of Halloween in Celtic and Catholic contact" but doesn't state, on the page itself, whether Santino argues for intentional replacement or gradual blending. That gap makes it a teacher-led listening extension rather than a third citation-log entry students summarize on their own.
The second optional piece moves into primary-source territory. Wikipedia references Serglige Con Culainn, a medieval Irish narrative describing a weeklong Samhain observance (Wikipedia). Handle it as an optional primary-literary-source exercise, not required reading for the core activity: it's a story text, not an administrative or eyewitness record, so it confirms that medieval storytellers invoked Samhain in narrative form without proving how the festival was practiced or whether it survived unbroken into modern Halloween.
Evidence table for the core replacement question
Source What it is What it states What it leaves open Library of Congress guide institutional summary feast days "were intended to substitute for Samhain and ultimately to replace it" no primary document or dated proof of intent is cited alongside the claim Wikipedia, Samhain entry encyclopedia synthesis churches in Ireland and Northumbria held an all-saints feast by roughly 800; the Frankish Empire adopted November 1 in 835 doesn't state whether the timing was meant to erase Samhain, and its own sources for these dates aren't traced here
Citation-log template
Every entry needs five fields:
- Source (author or institution):
- Date of publication (separate from the date of the historical event being described):
- Source type:
- Passage used (quote or paraphrase):
- What it doesn't establish:
A completed sample entry for the Library of Congress source looks like this:
- Source: Library of Congress, "Introduction: Halloween & Día de Muertos Resources"
- Date of publication: undated guide page
- Source type: institutional educational summary
- Passage used: feast days "were intended to substitute for Samhain and ultimately to replace it"
- What it doesn't establish: no primary document or dated proof of intent is cited alongside the claim
Now the student's turn. Using the same five fields, log the Wikipedia entry's account of the 800 and 835 dates. Write one sentence stating what it directly confirms, and one sentence stating what remains unresolved between it and the Library of Congress account. Use original wording, backed by a quote or paraphrase, rather than borrowing a sentence from this lesson.
Extension work: the other three fragments

Treat this as separate work, not part of the same 45-minute session. A second class period or a homework block works well as a suggested format for the extension, though teachers can adjust based on class length.
Fragment 1, early Samhain descriptions (grades 6 through 8). Give students two preselected excerpts with metadata already filled in: the Library of Congress's description of Samhain as a "pre-Christian Celtic festival of the dead" (LOC), and Wikipedia's more cautious note that Samhain "was not recorded in detail until the early modern era" (Wikipedia). Ask students to identify which sentence is a summary and which is a hedge, then explain the difference in one sentence each.
Fragment 3, continuity and blending. The Library of Congress guide also asserts that "elements of Christian and pre-Christian belief mingled, creating the popular festival of Halloween, or All Hallows Eve, the festival we still observe today" (LOC). Have students compare this blending claim to the replacement claim they already tested, keeping in mind that this is what the guide states occurred, not an independently documented account of the process itself. Write one sentence explaining how the two explanations differ.
Fragment 4, North American arrival (grades 9 through 12). Test the claim, made only in Wikipedia's Samhain entry, that most North American Halloween traditions arrived through 19th-century Irish and Scottish immigration (Wikipedia). Locate one additional source and apply the Stanford History Education Group's "Three Questions" from the PBS NewsHour Classroom lesson: who is behind the information, what is the evidence, and what do other sources say?
The PBS lesson defines a "zombie claim" as misinformation that recirculates repeatedly over time (PBS NewsHour Classroom). It works as a lens for spotting unsourced repetition online, not as a verdict on Samhain itself.
Running the lesson and grading student conclusions
For the core activity, budget 45 minutes: restate the search question (5 minutes), read the two sources and complete the citation log (15 minutes), fill out the evidence table including the "what it leaves open" column (15 minutes), then write a short conclusion (10 minutes). Budget the extension work separately, at roughly 30 to 40 minutes, as a suggested timeframe rather than a fixed figure.
The assessment criteria ask for three things in the student's own words, each backed by a quote or paraphrase:
- one statement a source makes directly
- one statement that is interpretation rather than fact
- one open question the evidence doesn't resolve
Don't require fixed sentence starters. Require evidence instead. A student who writes "Wikipedia confirms the 800 feast date but doesn't say why churches chose it" has met the bar, even without a template sentence to fill in.
What to do next

Whether the November feast days were meant to replace Samhain stays unresolved on the evidence gathered here. The guide states intent directly, while Wikipedia's entry supplies overlapping dates without addressing intent at all (LOC; Wikipedia). Answering the question more confidently would require stronger primary or scholarly sources than the two used in the core activity.
Pick one concrete next step: trace one of Wikipedia's own footnotes for the 800 or 835 date, or locate an independent source for one of the extension fragments. Either way, record what it confirms and what it leaves unresolved in the same citation-log format used here, and check with the teacher on whether the assignment needs a formal source list or annotated bibliography before turning in a final conclusion.
