“Understanding how power and human nature shape world politics”
⭐ 1. What is Classical Realism?
Classical Realism is one of the oldest theories in International Relations.
It says:
👉 World politics is driven by human nature, which is selfish, competitive, and power-seeking.
👉 Because humans behave this way, states also behave this way.
In simple words:
States try to gain power because humans like power.
War and conflict happen because humans and states want to protect themselves or dominate others.
⭐ 2. Main Ideas of Classical Realism
✔ 1. Human Nature is Selfish
Classical realists believe humans have basic desires for:
- Power
- Security
- Control
- Survival
Since states are made of humans, states also act in selfish ways.
✔ 2. International System is Anarchic
Anarchy means:
- There is no world government
- No authority above states
- No one to enforce rules
So states cannot trust each other fully.
✔ 3. Survival is the Most Important Goal
Every state wants to protect its people and territory.
To survive, states:
- Build armies
- Form alliances
- Increase power
✔ 4. Power is the Main Currency in World Politics
Power = military strength + economic capability + political influence.
States compete for power to stay safe.
✔ 5. War is Sometimes Unavoidable
Because states want power and do not trust each other, conflicts and wars happen.

(in very easy English)
1️⃣ Politics is based on human nature.
2️⃣ States act in terms of national interest.
3️⃣ National interest is mainly about power.
