what was the first country in the world

There isn’t a single agreed-upon answer, because “first country” depends on what you mean by country. Historians often point to Iran , Egypt , or Japan depending on whether you mean earliest organized government, earliest continuous state, or earliest sovereignty.

Why it varies

• Iran is often listed as the oldest by earliest known organized government, with dates around 3200 BCE.

• Egypt is also a common answer, especially when the focus is on early dynastic state formation around 3150 BCE.

• Japan is sometimes called the oldest continuous monarchy or sovereign state, with a traditional founding date of 660 BCE.

Simple answer

If you want the most common “oldest country” answer in popular lists , it is usually Iran.
