This document summarizes William Butler Yeats' poem "The Rose Tree" and its themes. It notes that Yeats was an Irish poet from a Protestant family whose lover Maud Gonne supported the British Army. The poem uses symbols like a rose tree and bitter sea to depict a conversation where two people discuss how political efforts have failed and the world has lost importance unless watered by nationalism, with the garden serving as a metaphor for the world. It ultimately argues the poem aims to advocate for Irish independence through depicting the Irish movement.
