Knocknagow by Charles Kickham was published in 1879 and became one of the most popular novels in Ireland. Its influence derived from its political importance, rather than its literary merits. It attacks the landlord system in Ireland and, indirectly, the English rule which supported the system.
For many years Knocknagow, or The Homes of Tipperary, was the book (along with a prayerbook) most likely to be found in every Irish home. Yeats described it as "The most honest of Irish novels" and Con Houlihan as "The greatest Irish novel".
