Unit 1 Overview: Political Systems, Regimes, and Governments

Unit 1 of the AP Comparative Politics course introduces students to the way comparative political scientists think to draw analysis and conclusions about global politics. There are big ideas that students have to keep in mind when studying Comparative politics, and the first one is that politics is all aboutย powerย andย authority. ๐Ÿซ…

In analyzing the six core countries of the AP exam keep in mind these questions: Who has the power and who is affected by it? How did they get this power? The political history of each nation will provide you with the answers to those questions. ๐Ÿ˜Ž

This unit will also provide you with the tools to incorporateย quantitativeย andย qualitativeย data so you can generate meaningful conclusions to identify and explains trends and patterns in other nations - basically to do what political scientists do!ย 

(Remember: Quantitative data is expressed in numerical form and can be analyzed statistically. Qualitative data contains non-numerical representations such as words, images and text.)ย 

Before we get into unit 1, let's take a quick second to look at the course as a whole. The course is divided into 5๏ธโƒฃ five units covering:ย 

  • How government gains power ๐Ÿ’ช and legitimacy
  • Institutions (stable, long-lasting organizations that help turn political ideas into actual policy. Think of legislatures and political parties!)
  • Culture and participation ๐Ÿ—ณ๏ธ (social factors are extremely important in understanding political systems!)
  • Elections and Citizen Organizations ๐Ÿ‘ฅ
  • Political and economic ๐Ÿ’น change

Core Course Countries

The course will ask you to demonstrate what you have learned about each of these topics through six 6๏ธโƒฃ countries, called the Core Course Countries. These nations were chosen by the College Board because they present distinct features that can explain the different ramifications of politics across the world

  1. UK ๐Ÿ‡ฌ๐Ÿ‡ง: When you use the term UK or United Kingdom we are referring to the combination of Scotland ๓ ง๓ ข๓ ณ๓ ฃ๓ ด๓ ฟ๐Ÿด๓ ง๓ ข๓ ณ๓ ฃ๓ ด๓ ฟ, Great Britain ๐Ÿ‡ฌ๐Ÿ‡ง, and Northern Ireland ๐Ÿ‡ฎ๐Ÿ‡ช. Key Characteristics of the UK: Democratic ๐Ÿ™‹regime, as well as a parliamentary system.
  1. Russia ๐Ÿ‡ท๐Ÿ‡บ: Russia came into existence again after the Soviet Union broke up in 1991. Russia is used as an example of an authoritarian regime, post-communist nation that exhibits a semi-presidential system.ย

  1. Iran ๐Ÿ‡ฎ๐Ÿ‡ท as a course country is quite interesting because it is an authoritarian regime, but it is also an example of a theocratic government. Unlike the first two course countries, the UK and Russia, Iran cannot be identified as a semi-presidential, presidential, or parliamentary system, but more on that inย Unit 2 Political Institutionsย

  1. Mexico ๐Ÿ‡ฒ๐Ÿ‡ฝ: This country, much like the UK, is an example of a democratic regime, however unlike the UK, Mexico is an example of a presidential system.ย ย

  1. China ๐Ÿ‡จ๐Ÿ‡ณ: This country is an authoritarian regime, similar to Russia and Iran. Much like Iran, the course does not categorize China as a presidential, semi-presidential, or parliamentary system, but once again we will talk about that inย Unit 2 Political Institutions.ย

  1. Nigeria ๐Ÿ‡ณ๐Ÿ‡ฌ:ย This country, much like the UK, is an example of a democratic regime, however unlike the UK, Nigeria is similar to Mexico in that it is an example of a presidential system.ย ย

In addition, you also need to know about Supranational Organizations. These are organizations like the EU ๐Ÿ‡ช๐Ÿ‡บ that encourage states to pool their sovereignty together in order to receive economic, political, and social benefit, but more on that later.
