A Concise History of Ireland covers the manners, customs, and institutions of the Ancient Irish up to the Industrial Progress of the year 1905 when the text was written. The book consists of 1000 numbered paragraphs and is written in a rather dense and detailed style. It helps to already have some notions of Irish history before starting this book.
Even though the book is somewhat dated, there is a lot of information contained in it. It can be a bit overwhelming trying to keep straight all of the battles, rebellions, and historical figures mentioned. Ireland is definitely rich in history, especially in its past as a British colony and with the historical conflicts between Catholics and Protestants, landlords and peasants, Celtic and Anglo-Norman cultures, etc.
I found this book to be somewhat of a dense read. If you are interested in a highly detailed account of Irish history, you might enjoy this book.
