Book of Invasions

The people of Ireland in medieval times never believed that the Gaelic speaking people were native to their land. They believed that Ireland was invaded and settled by successive Celtic tribes over different periods. Their history is based largely upon the pseudo-historical Lebor Gabala, translated into English as the "Book of Invasions", and Cath Maige Tuired, or the "Second Battle of Maige Tuired".

On this page we will recount the mythical Book of Invasions, as well as the real invasions of Ireland. We have also included sections on the Fomorians and Firbolgs who appear in the Book of Invasions.
