United States Territorial Acquisitions (1607-1853) Matching Activity - Identify the correct letter, date, title, and description for each U.S. territorial expansion.

Explanation:
We need to match each letter on the map (A–H) with the correct historical event—specifically, the year, title, and description of a U.S. territorial acquisition between 1607 and 1853.

Let’s go step by step using known U.S. territorial expansions and the map regions:

First, identify what each region likely represents based on shape and location:

- A: Northeast — Original 13 Colonies (east coast, from Maine to Georgia)
- B: Midwest/Ohio Valley — Northwest Territory, later states like Ohio, Indiana, Illinois; but more precisely, this area was part of the Northwest Ordinance lands, but not a single purchase. However, for matching purposes, we’ll see which acquisition fits best.
- C: Florida — clearly the Florida Peninsula
- D: Midwest/Great Lakes region — possibly part of Louisiana Purchase or later acquisitions.
- E: Texas — distinct shape, south of Oklahoma, west of Louisiana.
- F: Southwest — includes Arizona, New Mexico, maybe parts of Utah/Nevada → likely Mexican Cession.
- G: Pacific Northwest — Oregon Country (modern WA, OR, ID)
- H: California — coastal, south of Oregon, west of Nevada/AZ.

Now match descriptions and dates:

17. “This land was bought from France for $15 million.” → Louisiana Purchase (1803)
→ Covers central U.S., roughly from Mississippi River to Rockies — that’s D (the big central area).

18. “This land was bought from Mexico for $10 million.” → Gadsden Purchase (1853)
→ Small strip in southern AZ/NM — likely part of F, but since F is larger (Mexican Cession), Gadsden is a smaller addition *to* that. But in many maps, Gadsden is shown as the southernmost tip of the Southwest region — still F is the main Mexican Cession, so Gadsden may be a sub-part. However, the question treats them separately, and only one letter per blank. Let’s hold and check others.

19. “This land was gained from an agreement with England after America won the Revolutionary War.” → Original 13 Colonies (1783 Treaty of Paris)
→ That’s the eastern seaboard → A

20. “This land was gained from Spain with the Adams–Onís Treaty.” → Florida Annexation (1819)
→ Florida peninsula → C

21. “This land was gained through an agreement with England and resulted in the United States reaching the Pacific Ocean.” → Oregon Territory (1846)
→ Pacific Northwest → G

22. “This land was gained after the U.S.-Mexican War and the Treaty of Guadalupe Hidalgo.” → Mexican Cession (1848)
→ Covers CA, NV, UT, AZ, NM, CO, NM, TX? Wait—Texas was annexed earlier. Mexican Cession is ~1848, includes CA, AZ, NM, NV, UT, CO, NM, and parts of WY, OK, KS — that’s F (Southwest large block)

23. “This land along the Atlantic Coast was gained through British colonization.” → Original 13 Colonies again? But #19 already used that. Wait — description says “gained through British colonization”, not treaty. That refers to the original colonies *before* independence — but the date would be 1607 (Jamestown) onward. The *title* “Original 13 Colonies” is listed as #10. So #23 matches A, but #19 also points to A? Conflict.

Let’s list all items with known facts:

Key acquisitions:

- 1607: Jamestown founded — start of English colonization → leads to Original 13 Colonies. So #3 = 1607 → title: Original 13 Colonies (#10) → region A
- 1783: Treaty of Paris ends Revolutionary War → U.S. recognized, gets territory east of Mississippi (Original 13 + some western claims) — but the *land* was already occupied; the recognition came in 1783. Description #19 says “gained from an agreement with England after America won the Revolutionary War” → that’s 1783, but the *territory* is still the Original 13 + NW Territory. However, the Original 13 Colonies title is tied to the founding era, while the *formal recognition* is 1783. In many textbooks:
- 1607 = start of colonization
- 1783 = formal sovereignty over the 13 states

But the matching list has:
- #3: ____ 1607
- #10: Original 13 Colonies
So likely: 3 → 10 (1607 + Original 13 Colonies) → region A

Then #19 (1783?) — but 1783 is not in the year list! Wait, years given are:
1. 1845
2. 1803
3. 1607
4. 1853
5. 1846
6. 1848
7. 1783
8. 1819
9. Oregon Territory
10. Original 13 Colonies
11. Texas Annexation
12. Florida Annexation
13. Gadsden Purchase
14. Treaty of Paris
15. Louisiana Purchase
16. Mexican Cession

Ah! So the left column (1–8) are years, right column (9–16) are titles. Then 17–24 are descriptions to match to letters A–H.

So we must:
- Match each year (1–8) to a title (9–16) — but actually, the instruction says: “Match the correct letter with the correct Date, Title, and Description”. And the blanks are numbered 1–8 (years) and 17–24 (descriptions). Likely, each letter A–H corresponds to one acquisition, and we fill in:
For each letter (A–H), we need to pick:
- One year (1–8),
- One title (9–16),
- One description (17–24)

But the format shows blanks like:
1. ____ 1845
→ means: which letter goes with year 1845?

Similarly, 17. ____ This land was bought from France...

So actually:
- Blanks 1–8: enter the letter (A–H) that matches that year.
- Blanks 9–16: enter the letter that matches that title.
- Blanks 17–24: enter the letter that matches that description.

But the worksheet shows:
1. ____ 1845
2. ____ 1803
...
9. ____ Oregon Territory
10. ____ Original 13 Colonies
...
17. ____ This land was bought from France...

So yes: each blank expects a single letter (A–H).

Let’s build a table of acquisitions:

| Year | Event | Title (from 9–16) | Description (17–24) | Region (Letter) |
|------|-------|-------------------|------------------------|-----------------|
| 1607 | Jamestown founded → start of English colonies | Original 13 Colonies (#10) | #23: “gained through British colonization” | A |
| 1783 | Treaty of Paris ends Revolutionary War → U.S. gains sovereignty over 13 states & territory to Mississippi | Treaty of Paris (#14) | #19: “gained from agreement with England after Revolutionary War” | A? But same region. Hmm — conflict. Actually, the *land* of the 13 colonies was settled starting 1607, but formally recognized in 1783. However, in such maps, A is always the original 13 colonies, matched with 1607 and #10 and #23. Then 1783/Treaty of Paris is often linked to the *international recognition*, but the territory didn’t expand — so maybe #7 (1783) matches A too? But each letter used once.

Wait — look at the map: 8 regions A–H, and 8 years (1–8), 8 titles (9–16), 8 descriptions (17–24). So it’s a 1-to-1 mapping: each letter corresponds to exactly one year, one title, one description.

So we need to assign A–H uniquely.

Let’s list standard U.S. territorial acquisitions with years:

1. 1607 – Jamestown; beginning of English colonization → Original 13 Colonies (title #10); description #23 (“British colonization”) → region A

2. 1783 – Treaty of Paris; U.S. recognized, gets territory up to Mississippi — but no *new* land beyond colonies; however, some maps include the Northwest Territory claim. But more commonly, Treaty of Paris is paired with 1783 and description #19. Which region? The original colonies plus claims → still A? Can’t duplicate.

Alternative: Maybe B is the Northwest Territory, acquired via Treaty of Paris 1783. The Treaty of Paris gave U.S. control of land north of Ohio River to Mississippi — that’s the Northwest Territory, which became OH, IN, IL, MI, WI, MN. That’s region B (midwest east of Mississippi, north of Kentucky/TN). Yes! So:
- 1783 → Treaty of Paris (#14) → description #19 → region B

Then:
- 1803 → Louisiana Purchase (#15) → bought from France $15M → description #17 → region D (central, from MS River to Rockies)

- 1819 → Adams-Onís Treaty → Florida (#12) → description #20 → region C

- 1845 → Texas Annexation (#11) → Texas became state in 1845; it had been independent republic since 1836 → description #24: “gained independence in 1836 and was a Republic for 9 years before annexation” → yes! 1836 + 9 = 1845. So 1845 → Texas Annexation → #24 → region E

- 1846 → Oregon Treaty with Britain → Oregon Territory (#9) → description #21: “agreement with England and resulted in U.S. reaching Pacific Ocean” → region G

- 1848 → Treaty of Guadalupe Hidalgo → Mexican Cession (#16) → description #22 → region F (SW: CA, AZ, NM, etc.)

- 1853 → Gadsden Purchase (#13) → bought from Mexico $10M → description #18 → small strip south of Mexican Cession, still part of F? But we need unique region. However, on many maps, Gadsden is shown as part of the same Southwest block, but since F is already used for Mexican Cession, and Gadsden is a later addition, perhaps the map lumps them, but the problem gives 8 distinct regions, so likely:
- H = California? But CA is part of Mexican Cession.
Wait, look at map letters:
- A: East coast (13 colonies)
- B: Great Lakes/Midwest (Ohio Valley)
- C: Florida
- D: Louisiana Purchase core (MO, AR, IA, etc.)
- E: Texas
- F: Southwest (NM, AZ, UT, NV, CO)
- G: Oregon Country (WA, OR, ID)
- H: California specifically? But CA is west of F. In the map, H is the far west coast, below G and west of F — that’s California.

But Mexican Cession includes California. So why separate H? Possibly:
- F = New Mexico/Arizona portion
- H = California

But historically, all were acquired together in 1848. Unless… the California Gold Rush era, but no.

Alternative: Let's count required unique regions:

Acquisitions:
1. Original 13 Colonies — A
2. Northwest Territory (via 1783) — B
3. Louisiana Purchase — D
4. Florida — C
5. Texas — E
6. Oregon — G
7. Mexican Cession — F
8. Gadsden Purchase — H (southern AZ/NM strip, often shown as lower part of SW, but if map has H as a separate southern piece, maybe H)

Yes, many worksheets draw Gadsden as a small southern chunk labeled H.

Also, description #18: “bought from Mexico for $10 million” → Gadsden Purchase (1853) → letter H

Then description #17: “bought from France $15M” → Louisiana Purchase (1803) → D

Now assign all:

- 1. 1845 → Texas Annexation → letter E
- 2. 1803 → Louisiana Purchase → D
- 3. 1607 → Original 13 Colonies → A
- 4. 1853 → Gadsden Purchase → H
- 5. 1846 → Oregon Territory → G
- 6. 1848 → Mexican Cession → F
- 7. 1783 → Treaty of Paris → B (Northwest Territory claim)
- 8. 1819 → Florida Annexation → C

Titles:
- 9. Oregon Territory → G
- 10. Original 13 Colonies → A
- 11. Texas Annexation → E
- 12. Florida Annexation → C
- 13. Gadsden Purchase → H
- 14. Treaty of Paris → B
- 15. Louisiana Purchase → D
- 16. Mexican Cession → F

Descriptions:
- 17. bought from France $15M → Louisiana Purchase → D
- 18. bought from Mexico $10M → Gadsden Purchase → H
- 19. gained from England after Rev War → Treaty of Paris 1783 → B
- 20. gained from Spain, Adams-Onís → Florida → C
- 21. agreement with England, reach Pacific → Oregon → G
- 22. after U.S.-Mexican War, Guadalupe Hidalgo → Mexican Cession → F
- 23. Atlantic Coast, British colonization → Original 13 Colonies → A
- 24. independent 1836, republic 9 years, annexed → Texas → E
