When was Andorra created?

Andorra was not created, as such. Its history is long and complex, involving a series of alliances, treaties, and political manoeuvring that eventually resulted in the formation of the modern state. While some have tried to pinpoint its origin at specific moments in history, such as 1278 when its co-princes were first established, scholars generally recognise that modern Andorra is the product of a historical evolution rather than a single origin.
