AMSCO 6.14 Continuity and Change Period 6

Overview

AMSCO Topic 6.14, Continuity and Change in Period 6, wraps up Unit 6 by asking the big question of the whole period: how much did industrialization actually change the United States from 1865 to 1898? Unlike the other chapters in the unit, this one is mostly a skills chapter. It shows you how to build a complex continuity-and-change argument about industrialization, how to handle contextualization questions on the AP exam, and how to write an essay introduction that works as both a blueprint and a piece of historical framing. Think of it as the chapter that teaches you how to use everything you learned in Topics 6.1 through 6.13.

Continuity and Change in Industrialization, 1865-1898

The chapter's central example is the prompt "Explain the extent to which large-scale industries changed markets in the United States from 1865 to 1898." You could argue that larger, more efficient manufacturers like Carnegie Steel were actually a continuation of long-term trends toward bigger, more efficient production, not a total break with the past.

That's a defensible thesis, but the AP exam rewards complexity. AMSCO shows three ways to push the argument further:

• Corroborate the argument with evidence from other industries. Rockefeller's Standard Oil also improved efficiency and bought up competitors until it dominated the oil industry, so the pattern wasn't unique to steel.
• Qualify the argument by admitting real changes. Carnegie used vertical integration, controlling every stage of production from raw materials to finished steel, which was genuinely new.
• Modify the argument by noting exceptions. Some markets stayed dominated by regional businesses, like local railroads and breweries, so consolidation never reached everywhere.

Corroborate, qualify, modify. That trio is AMSCO's recipe for the complexity point on a long essay. You take a solid claim and then show you understand the evidence that supports it, complicates it, and limits it.

Other angles a question might take

The exam could focus a continuity-and-change question on any single factor of industrialization, including:

• Markets (national vs. regional businesses)
• Technological innovation
• Government policies
• Migration
• Urban development

Whatever the angle, the move is the same: identify what genuinely changed, what continued from earlier eras, and how far the change actually went. For the underlying content, review the rise of industrial capitalism in AMSCO 6.6 and labor in the Gilded Age in AMSCO 6.7.

Think as a Historian: Contextualization

Contextualization means placing a specific person, event, object, or place into the broader historical picture around it. AMSCO breaks the skill into two directions, and exam questions can run either way:

• Identify a context. The question gives you something specific, and you describe the bigger picture it belongs to.
• Explain specifics. The question gives you the big picture, and you supply concrete examples connected to it.

Example 1: Barbed wire (specific to context)

If a question names barbed wire, you could identify several valid contexts:

• The rise of the cattle-ranching industry in some western states
• The pushing of Native Americans off their lands
• The closing of the American frontier
• The establishment of the cattle frontier

Any of these works because each is a broader development that barbed wire was part of. The western expansion background lives in AMSCO 6.2 on westward economic development.

Example 2: The labor movement (context to specifics)

If a question names the broad context of the labor movement and asks for specifics, you could mention:

• Names of specific labor leaders or business owners
• A specific strike
• One aspect of industrial warfare, such as blacklists

Contextualization items can show up anywhere on the AP exam, in multiple choice, short answers, the DBQ, and the LEQ. AMSCO's advice is blunt: the easiest way to get comfortable with this skill is to practice it.

Write as a Historian: Writing the Introduction

Once you've analyzed the task, gathered and organized evidence, and developed a thesis, the hardest remaining job in a long essay is the introduction. AMSCO says a good introduction does two things at once.

The introduction as blueprint

Your introduction should convey the framework or limits of the topic plus a clear, debatable, defensible claim, stated in one or more sentences in the same location (ideally the introduction itself). It should also suggest your organizational pattern and reasoning process, whether that's causation, continuity and change, or comparison. Without saying it outright, the intro tells the reader: here's what I'm going to argue, here's the reasoning process I'll use, and here's the order my ideas will come in.

The introduction as historical perspective

A good introduction also demonstrates contextualization by relating the prompt's topic to broader events, developments, or processes that occur before, during, or after the time frame of the question. The intro is a smart place to state this historical perspective, but you'll need to develop it further in the body.

AMSCO's sample introduction

The chapter models this with an intro arguing that the rise of industrial capitalism between 1865 and 1898 marked a dramatic break with earlier economic values. It contextualizes by reaching back before the period: the Puritans' beliefs about work, the individualism represented by Benjamin Franklin, and Henry Clay's pragmatic use of government were left behind as the country developed new ways to think about the economy. It then frames the shift even more broadly, as part of a larger cultural move away from individualism reflected in politics and the arts. Notice that's a blueprint (the essay will trace a break with three older traditions) and a perspective (the change connects to culture beyond economics).

Putting Unit 6 Together: What Changed, What Continued

Topic 6.14 only works if you can pull evidence from across the unit. Here's the period in one pass:

• Industrial capitalism rose thanks to technological advances, large-scale production methods, and new markets. Massive technological change, expanding international communication networks, and pro-growth government policies fueled rapid economic development and business consolidation.
• Perspectives on the economy and labor diversified during a time of financial panics and downturns.
• Agriculture consolidated too. New systems of production and transportation, plus periods of instability, spurred a variety of responses from farmers.
• Migration transformed the country. International and internal migration swelled urban populations and built a new urban culture, while migrants moving west in search of land and opportunity frequently provoked competition and violent conflict. Review AMSCO 6.8 on immigration and migration for the details.
• The Gilded Age produced new cultural and intellectual movements that both buttressed and challenged the social order, along with political debates over citizenship, corruption, and the proper relationship between business and government.

Any of these threads can anchor a continuity-and-change argument. The strongest essays pick one, make a claim about the extent of change, then corroborate, qualify, and modify.
