Sequent occupance is the concept that successive societies each leave their cultural imprint on a place, so the cultural landscape you see today is a layered record of every group that has lived there, from street names and architecture to religious sites.
Sequent occupance is the idea that places are like layer cakes. Every society that occupies a location adds its own layer to the cultural landscape, and those layers stack up over time instead of erasing each other. Walk through Mexico City and you can see Aztec ruins, Spanish colonial cathedrals, and modern skyscrapers within a few blocks. That's sequent occupance made visible.
In AP Human Geography, this concept lives in Topic 3.3 (Cultural Patterns) and connects directly to EK PSO-3.D.1, which says regional patterns of language, religion, and ethnicity contribute to a sense of place and shape the global cultural landscape. Sequent occupance explains why a single place can have multiple languages on its signs, several religious buildings from different faiths, and architecture from three different centuries. Each occupying group transformed the space, and the next group built on top of (not instead of) what came before.
Sequent occupance supports learning objective AP Human Geography 3.3.A, which asks you to explain patterns and landscapes of language, religion, and ethnicity. It's the time-lapse version of the cultural landscape concept. If the cultural landscape is a snapshot of human imprints on a place, sequent occupance is the whole photo album. It explains how places get their layered character through historical settlement, migration, and colonization. This matters for Unit 3's bigger themes too. Those accumulated layers can build a strong sense of place (a centripetal force) or create tension between groups who claim different layers of the same landscape (a centrifugal force, per EK PSO-3.D.2). When the exam asks you to interpret a photo of a landscape with mixed cultural elements, sequent occupance is often the concept doing the explaining.

Cultural Landscape (Unit 3)
The cultural landscape is what sequent occupance produces. Every layer of occupance leaves visible evidence (buildings, place names, religious sites), and the landscape you observe today is the sum of all those layers. You can't fully explain a cultural landscape without asking who lived there before.
Cultural Diffusion (Unit 3)
Diffusion is how new cultural traits arrive; sequent occupance is how they pile up. When a new group migrates into a place or a colonizer takes over, relocation diffusion delivers a fresh set of traits that becomes the next layer in the stack.
Ethnic Enclave (Unit 3)
Ethnic enclaves are sequent occupance happening in fast-forward at the neighborhood scale. A neighborhood that was Italian in 1920, Puerto Rican in 1970, and Dominican today often keeps traces of each wave, like an old Italian church now holding Spanish-language services.
Cultural Assimilation (Unit 3)
Assimilation can blur or erase earlier layers as groups adopt the dominant culture, while resistance to assimilation keeps older imprints visible. Whether layers survive or fade depends on how much each group assimilates into the next.
Sequent occupance most often shows up in multiple-choice questions paired with a photo or description of a landscape showing imprints from multiple eras or cultures, like a mosque converted to a cathedral or colonial architecture next to indigenous structures. Your job is to recognize the layering and pick sequent occupance over lookalike answers like cultural diffusion or assimilation. No released FRQ has used the term verbatim, but FRQs regularly ask you to explain how the cultural landscape reflects the groups who shaped it, and sequent occupance gives you the vocabulary to do that with precision. If you can name a specific layered place (Istanbul, Mexico City, New Orleans) and identify two or more cultural layers in it, you're exam-ready.
The cultural landscape is the visible result of human activity on a place, viewed as it exists right now. Sequent occupance is the process that built it over time, with each successive society adding its own layer. Think of the cultural landscape as the finished lasagna and sequent occupance as the recipe that stacked the layers. On an MCQ, if the question emphasizes successive groups over time, the answer is sequent occupance; if it emphasizes the visible human imprint itself, it's cultural landscape.
Sequent occupance means each society that occupies a place leaves its cultural imprint, creating a layered cultural landscape over time.
It lives in Topic 3.3 and supports AP Human Geography 3.3.A by explaining how language, religion, and ethnicity patterns become visible in the landscape.
The key word is 'successive.' Sequent occupance is about multiple groups over time, not just one culture's imprint.
Classic examples include Mexico City (Aztec, Spanish colonial, modern layers) and Istanbul (Roman, Byzantine, Ottoman, modern Turkish layers).
Per EK PSO-3.D.1 and 3.D.2, these accumulated layers contribute to sense of place and can act as centripetal or centrifugal forces depending on how groups relate to them.
On the exam, photos showing mixed-era or mixed-culture landscapes are your cue to think sequent occupance.
Sequent occupance is the concept that successive societies each leave their cultural imprint on a place, so the cultural landscape becomes a layered record of everyone who lived there. It's tested in Unit 3, Topic 3.3 (Cultural Patterns).
The cultural landscape is the visible human imprint on a place as it exists now; sequent occupance is the time-based process where successive societies stacked those imprints. Landscape is the result, sequent occupance is the layering process.
No. The whole point is that earlier imprints usually survive in some form, like Aztec ruins under Mexico City or Roman walls in Istanbul. Erasure is closer to assimilation or cultural replacement; sequent occupance emphasizes accumulation.
Mexico City works well. You can point to Aztec (Tenochtitlan) ruins, Spanish colonial cathedrals and plazas, and modern global architecture all in the same city, which gives you three distinct cultural layers to name in an answer.
No. Diffusion is how a cultural trait spreads from one place to another, while sequent occupance is what happens after groups arrive and occupy a place, layering their imprints over previous occupants'. Diffusion delivers the layers; sequent occupance stacks them.
