Recently, I began delving into ancient history with the goal of having a clearer understanding of our history, so far, I've studied the ancient Near East's history and the one thing that gets me scratching my head the most is the identity of the Sea Peoples who caused the Late Bronze Age collapse. There are several theories on who they were and linking some of their tribes to certain regions, for example, the Sherden being linked to Sardinia and the Shekelesh being linked to Sicily.

But I want to know the truth, were they ethnically Greek or a loose confederation of tribes coming from the Mediterranean, as hypothetised by John Chadwick?

Thanks for answering :)
