Bahrain
In short
Bahrain is an island nation located in West Asia within the Persian Gulf. It consists of a small archipelago of natural and artificial islands situated between Qatar and Saudi Arabia.
In plain words
It is a small country made up of many islands in the sea. Most of the land is one main island, and people can drive to Saudi Arabia using a long bridge called the King Fahd Causeway.
A simple example
A traveller could fly into Manama and then take a short drive across the causeway to reach the mainland of Saudi Arabia.
Why it matters
Its location in the Persian Gulf makes it a key hub for trade and finance in the Middle East. It also has a large population of expatriates who live and work there.
Easy to mix up
Do not confuse it with the country of Qatar, which is its neighbour across the water.
