More than 3,000 years ago a group of powerful and intricately connected Mediterranean kingdoms collapsed over the course of just a few decades. The palaces of Mycenaean Greece were destroyed, entire cities in Hittite Turkey were abandoned, and whole empires disintegrated. Some civilisations disappeared completely. But what caused the so-called Bronze Age collapse - climate change, trade breakdown, internal rebellion, or a mysterious group of invaders known as the ‘Sea Peoples'? Some historians have called the aftermath a 'dark age', but was it really as gloomy as that, and might this period of wealth, pressure, and decline offer us any lessons today?
