In the last few decades, the world has become more connected than ever before. The end of the Cold War, the spread of the internet and the growth of global trade have linked distant countries and shaped the world you are growing up in.
Why this matters The connected world affects daily life, from the phone in your pocket to the food on your table. Understanding how it came about helps you make sense of the news, technology and the shared challenges people everywhere now face together.
The end of the Cold War
After 1945, the world was divided for decades between two blocs: the United States and its allies, and the Soviet Union and its allies. This tense rivalry was called the Cold War.
- The Berlin Wall, which divided the German city of Berlin, fell in 1989.
- The Soviet Union broke apart in 1991, ending the Cold War.
- Many countries in Eastern Europe became free to choose their own governments.
New technology and the internet
New technology transformed how people live, work and communicate.
- The World Wide Web was invented by Tim Berners-Lee around 1989 to 1991.
- Mobile phones and the internet let people share information across the world in seconds.
- Ideas, news and cultures now spread faster than ever before.
Globalisation and shared challenges
Globalisation means the growing connection of the world's economies and cultures. It brings benefits and challenges.
- Goods, money, people and ideas move across borders more easily than at any time in the past.
- The clothes you wear and the food you eat may be produced in many different countries around the world.
- Shared challenges include climate change, disease and looking after the environment for future generations.
- Solving these problems often needs countries to cooperate and work together rather than act alone.
Common exam mistake: describing globalisation as only about technology and the internet. Strong answers also cover economic globalisation (the movement of trade, goods and money) and the shared global challenges it creates, such as climate change.
Exam technique: link the three parts of this topic together — explain how the end of the Cold War, new technology and globalisation are connected twentieth-century trends, not separate unrelated stories, and support each point with a specific date (Berlin Wall, 1989; World Wide Web, 1989 to 1991).
A single connected world can share both its knowledge and its problems in an instant.
