cultural nationalism in irish literature

[chellis]

Hi,

I'm interested in investigating cultural nationalism in Irish literature between 1798 and 1921, particularly centering on Yeats. Where do I start?! Can you reconmend a handful of politically themed Yeats poems and popular ballads of the era and any useful essays on the topic?

Thanks

Yeats poems on 1916 would be good ones.
